The structure and activity of nodulation-suppressing CLE peptide hormones of legumes 
April H. Hastwell, Peter M. Gresshoff and Brett J. Ferguson

CLE peptides are critical regulators of plant development, and include members that control legume nodule numbers in symbiosis with nitrogen-fixing rhizobia bacteria. These peptides are essential for the host plant to maintain a balance between acquiring nitrogen and expending energy forming and maintaining nodules. The structure and function of all known nodulation-suppressing CLE peptides is the focus of this review.

The variability in the xylem architecture of grapevine petiole and its contribution to hydraulic differences 
Uri Hochberg, Asfaw Degu, Tanya Gendler, Aaron Fait and Shimon Rachmilevitch

Grapevine (Vitis vinifera) is known for its cultivar variability in response to deficit irrigation. A 3 year study, comparing Shiraz and Cabernet Sauvignon petioles anatomy, showed that Shiraz had larger vessels diameter that resulted in higher hydraulic conductivity and transpiration rates. These traits lead to lower water potentials and vulnerability to cavitation. Our results provide a link between xylem anatomy and plant performances.

Sufficient leaf transpiration and nonstructural carbohydrates are beneficial for high-temperature tolerance in three rice (Oryza sativa) cultivars and two nitrogen treatments 

Extreme high temperature can threaten rice (Oryza sativa L.) production by decreasing its seed setting percentage; however, sufficient nitrogen can alleviate this detrimental effect. Heat-tolerant cultivars show high leaf transpiration and nonstructural carbohydrates, and sufficient nitrogen can improve them. This suggests that sufficient leaf transpiration and nonstructural carbohydrates are beneficial for high-temperature tolerance in three rice cultivars and two N treatments.

Plant hydraulic conductance adapts to shoot number but limits shoot vigour in grapevines 
Markus Keller, Laura S. Deyermond and Bhaskar R. Bondada

This study sought to provide a biophysical basis for the common observation that shoot vigour in grapevines declines as the number of shoots per plant increases. We found that the plant’s capacity to supply water to its canopy adapts to the shoot number; however, limited adaptation, rather than competition with fruit growth, may constrain shoot growth and fruit growth. These findings may be used to optimise cultural practices that balance shoot and fruit growth for maximum quality.

Intraspecific variation in leaf growth of wheat (Triticum aestivum) under Australian Grain Free Air CO2 Enrichment (AGFACE): is it regulated through carbon and/or nitrogen supply? 
Chamindathee L. Thilakarathne, Sabine Tausz-Posch, Karen Cane, Robert M. Norton, Glenn J. Fitzgerald, Michael Tausz and Saman Seneweera

Increased plant growth and yield response to elevated [CO2] is closely associated with leaf area expansion. The main aim of this study was to investigate the mechanism of leaf area expansion and its genetic plasticity. Our results suggest that carbon supplies to growing leaves are cultivar dependent, and well correlated with leaf area expansion and whole-plant growth.

Hydrogen peroxide promotes programmed cell death and salicylic acid accumulation during the induced production of sesquiterpenes in cultured cell suspensions of Aquilaria sinensis 
Juan Liu, Yanhong Xu, Zheng Zhang and Jianhe Wei

We investigated the formation of agarwood, a substance believed to have interesting medicinal properties and that is produced only by certain plants when they are responding to an injury or infection. We evaluated the effects of hydrogen peroxide on cells of the plant Aquilaria sinensis; as we expected, the plant cells responded to this damaging chemical with specific changes in gene expression and the production of compounds known to be linked with toxicity and programmed cell death. Our results indicate that exposure to a reactive oxygen species, such as hydrogen peroxide, produces multiple cellular responses that culminate in an effective defensive reaction on the part of the plant (i.e. production of agarwood).

On the evaluation of methods for the recovery of plant root systems from X-ray computed tomography images 
Stefan Mairhofer, Craig Sturrock, Darren M. Wells, Malcolm J. Bennett, Sacha J. Mooney and Tony P. Pridmore

The evaluation of root system recovery methods for X-ray microcomputed tomography images is a challenging task. In this work, we aim to raise awareness of the evaluation problem and to propose experimental approaches that allow the performance of root extraction methods to be assessed. This should help users to better understand the strengths and limitations of each method and should allow a better comparison.

Linking osmotic adjustment and stomatal characteristics with salinity stress tolerance in contrasting barley accessions 
Min Zhu, Meixue Zhou, Lana Shabala and Sergey Shabala

Soil salinisation is a global issue that affects plant growth and limits agricultural production, and a comprehensive understanding of the mechanism of salt tolerance is essential for breeding salt-tolerant genotypes. Our results indicate that higher stomatal density and a predominant use of inorganic osmolytes are critical for the osmotic adjustment when barley exposed to salinity stress. These findings offer breeders new phenotyping methods for screening salt-tolerant genotypes, and provide a new insight into mechanisms of salt tolerance in this species.

Water relations of an invasive halophyte (Spartina patens): osmoregulation and ionic effects on xylem hydraulics 
Valentino Casolo, Martina Tomasella, Valentina De Col, Enrico Braidot, Tadeja Savi and Andrea Nardini

Invasive plants pose serious risks for conservation of coastal habitats. Spartina patens revealed physiological mechanisms based on salt uptake and accumulation, and ability to control the capacity of the plant to transport water, thus allowing colonisation of both dunes and marshes. Studies are needed to investigate the eventual occurrence of similar mechanisms in native species outcompeted by alien ones.

Image-based estimation of oat panicle development using local texture patterns 
Roger Boyle, Fiona Corke and Catherine Howarth

High-throughput phenotyping facilities provide opportunities for plant development observation and monitoring on new scales, but also present new problems in automatic image analysis. This paper presents a solution to one such problem by automating the detection of flowering in oats. This demonstrates the applicability of state-of-the-art computer vision algorithms to phenotyping, which may well be of value in similar atlas-based measurement.

How different pruning severities alter shoot structure: a modelling approach in young ‘Nonpareil’ almond trees 
Claudia Negrón, Loreto Contador, Bruce D. Lampinen, Samuel G. Metcalf, Yann Guédon, Evelyne Costes and Theodore M. DeJong

Pruning clearly influences subsequent growth and structure of trees; however, systematic studies on shoot structural responses to pruning severity have been difficult due to shoot structural complexity. This research used a statistical modelling approach to characterise shoot structural responses to pruning severity in ‘Nonpareil’ almond trees. Shoot responses to pruning were relatively consistent and predictable among similar shoot types within pruning treatments while pruning severity increased shoot structural complexity.

Metabolomics deciphers quantitative resistance mechanisms in diploid potato clones against late blight 
Kalenahalli N. Yogendra, Ajjamada C. Kushalappa, Felipe Sarmiento, Ernesto Rodriguez and Teresa Mosquera

Potato production is threatened worldwide by late blight disease, which destroys crops and lays a heavy financial burden on producers. Diploid potatoes with high disease resistance were analysed for the first time to identify the resistance related metabolites and associated genes responsible for impeding the pathogen. Phenylpropanoids, flavonoids, fatty acids and alkaloids induced reinforcement of secondary cell walls deterring pathogen advancement, and the genes involved can be used in breeding following validation.

Seasonal changes in the photosynthetic response to CO2 and temperature in apple (Malus domestica cv. ‘Red Gala’) leaves during a growing season with a high temperature event 
Dennis H. Greer

Extreme summer temperatures are increasingly frequent and are known to cause a loss in crop productivity. The aim was to test the photosynthetic performance of economically important Malus domestica (apple) trees under these conditions and discovered that extreme heat compromised the photosynthetic process but recovery occurred when the temperatures subsided. These results provide a basis for comprehending the impact of climate change.

Auxin-modulated root growth inhibition in Arabidopsis thaliana seedlings with ammonium as the sole nitrogen source 
Huaiyu Yang, Jenny von der Fecht-Bartenbach, Ji?í Friml, Jan U. Lohmann, Benjamin Neuhäuser and Uwe Ludewig

Ammonium and NO3 are the major nitrogen sources of plants. Although NH4+ is preferred, plant growth is suppressed at higher concentrations. Here, the transcriptomes of seedlings grown on (NH4)2SO4, KNO3 or NH4NO3 were compared. A major difference in auxin-regulated genes was observed and the importance of auxin was confirmed using mutants in the auxin pathway.

Heterotrimeric G-proteins involved in the MeJA regulated ion flux and stomatal closure in Arabidopsis thaliana 
Suli Yan, Shuitian Luo, Shanshan Dong, Ting Zhang, Jingru Sun, Ningning Wang, Hongjun Yao and Yingbai Shen

Heterotrimeric G-proteins are important elements of the transmembrane signal transmission components. Researchers have indicated that MeJA induced stomatal closure in many species. However, whether heterotrimeric G-proteins involved in the MeJA induced stomatal signal cascade has not yet been evaluated. In this study, heterotrimeric G-proteins were found to regulate the transmembrane H+, Ca2+, K+ flux and then control stomatal closure in Arabidopsis thaliana guard cells response to MeJA. This result provides new insight into the signal cascade of MeJA-induced stomatal closure.

Ionic and photosynthetic homeostasis in quinoa challenged by salinity and drought – mechanisms of tolerance 
Fatemeh Razzaghi, Sven-Erik Jacobsen, Christian Richardt Jensen and Mathias Neumann Andersen

Global food production is limited by salinity and drought. Quinoa is a solution, producing seed even at seawater salinities. Unlike other crops, quinoa increased uptake of potassium at high salt concentrations, maintaining photosynthesis and improving water use efficiency. The saturated electrical conductivity resulting in 50% yield was estimated to be 25 dS m–1, higher than any other known crop.

Shoot branching in response to nodal roots is mimicked by application of exogenous cytokinin in Trifolium repens 
Roderick G. Thomas and Michael J. M. Hay

Regulation of axillary bud outgrowth in Trifolium repens is dominated by supply of a xylem-transported stimulatory signal from nodal roots. The present study shows this stimulus could be cytokinin-based. It suggests that, in contrast to its much reduced role in erect-stemmed species, xylem-transported cytokinin plays a key role in the outgrowth of axillary buds in prostrate nodally-rooting species.

Resilience of a semi-deciduous shrub, Cistus salvifolius, to severe summer drought and heat stress 
Olga M. Grant, Łukasz Tronina, José I. García-Plazaola, Raquel Esteban, João Santos Pereira and M. Manuela Chaves

Climate change is expected to exacerbate summer drought in Mediterranean environments. We analysed the response of a rockrose species to a heat wave superimposed on severe drought, discovering that a combination of physiological and biochemical adjustments allowed survival, with recovery following autumn rains. The shrub’s capacity to withstand substantial seasonal variability may also buffer the impact of significant inter-annual variation in water availability, indicating potential resilience to climate change in the understorey of Mediterranean oak woodlands.

Surface reconstruction of wheat leaf morphology from three-dimensional scanned data 
Daryl M. Kempthorne, Ian W. Turner, John A. Belward, Scott W. McCue, Mark Barry, Joseph Young, Gary J. Dorr, Jim Hanan and Jerzy A. Zabkiewicz

Realistic virtual models of leaf surfaces are important for several applications in plant sciences, such as simulating agrichemical spray droplet motion on the leaf surface. Although there are effective approaches for reconstructing leaf surface from 3D scanned data, complications arise when dealing with wheat (Triticum aestivum) leaves, which tend to twist and bend. We present an algorithm that overcomes this topological difficulty, allowing significantly more leaf varieties to be modelled in this way.

Blobs and curves: object-based colocalisation for plant cells 
Carl J. Nelson, Patrick Duckney, Timothy J. Hawkins, Michael J. Deeks, P. Philippe Laissue, Patrick J. Hussey and Boguslaw Obara

Quantifying the colocalisation of labels is a major application of fluorescent microscopy in plant biology. Pixel-based quantification of colocalisation, such as Pearson’s correlation coefficient, gives limited information for further analysis. We show how applying bioimage informatics tools to a commonplace experiment allows further quantifiable results to be extracted. We use our object-based colocalisation technique to extract distance information, show temporal changes and demonstrate the advantages and pitfalls of using bioimage informatics for plant science.

Seed coating reduces respiration losses and affects sugar metabolism during germination and early seedling growth in cereals 
Linda Gorim and Folkard Asch

We investigated how and why cereal seedlings performed better when grown from hydro-absorber coated seeds. We analysed the proportion of reserves mobilised for growth and respiration and sucrose mobilisation and found that mobilisation efficiency was higher resulting in higher biomass when cereals were coated and in each cereal, sucrose was mobilised differently. Further investigations into oxygen availability while imbibition is occurring have to be done.

Water use efficiency in Sangiovese grapes (Vitis vinifera L.) subjected to water stress before veraison: different levels of assessment lead to different conclusions 
Maria Clara Merli, Matteo Gatti, Marco Galbignani, Fabio Bernizzoni, Eugenio Magnanini and Stefano Poni

How grapevines (Vitis vinifera L.) use irrigation under drought needs to be determined. Previous work shows contradictory results regarding the method used. Single-leaf and whole-canopy methods for assessing water use efficiency (WUE) were compared in V. vinifera cv. Sangiovese subjected to progressive water deficit before veraison. Single-leaf WUE assessment was poorly correlated with yield and grape composition, whereas whole-canopy assessment was more reliable. Guidelines were that not less than 70% of daily water use should be supplied to Sangiovese vines before veraison.

Importance of natural cloud regimes to ecophysiology in the alpine species, Caltha leptosepala and Arnica parryi, Snowy Range Mountains, southeast Wyoming, USA 
Adriana Sanchez, Nicole M. Hughes and William K. Smith

Natural cloud regimes across the globe are expected to change with continued global warming. Yet, little is known about the impacts on plants, except for a few studies showing potentially strong effects on photosynthetic carbon gain and transpirational water loss. We found that these changes to the natural cloud regime had substantial impacts on photosynthesis, transpiration and water use efficiency.

Does age matter under winter photoinhibitory conditions? A case study in stems and leaves of European mistletoe (Viscum album) 
Fátima Míguez, Beatriz Fernández-Marín, Antonio Hernández, José Maria Becerril and José Ignacio García-Plazaola

European mistletoe (Viscum album) is an evergreen hemiparasitic plant characterised by a continuous photosynthetic surface composed of leaves and stems. We have taken advantage of these traits and used this species as a perfect model plant to study the interactive effect of age and winter on photosynthetic regulation. Winter, as in other temperate evergreens, induces a downregulation of photosynthesis, which in stems is compensated by an ageing-dependent stimulatory effect. Overall, this case study supports the theory of negative senescence.

High night temperature induces contrasting responses for spikelet fertility, spikelet tissue temperature, flowering characteristics and grain quality in rice 
Onoriode Coast, Richard H. Ellis, Alistair J. Murdoch, Cherryl Quiñones and Krishna S. V. Jagadish

High night temperature (HNT) can significantly reduce rice yield and quality. Flowering dynamics, spikelet tissue temperature determines seed-set among diverse rice genotypes exposed to early and/or late night temperature stress. Documented for the first time is a critical night temperature threshold of 27°C beyond which reduction in spikelet fertility is induced. The different sensitivities to HNT of cultivars for spikelet fertility and quality will complement plant breeding efforts targeted towards enhancing resilience of rice cultivars to warmer climates.

Raju Pushpavalli, Mainassara Zaman-Allah, Neil C. Turner, Rekha Baddam, Mandali V. Rao and Vincent Vadez

Ten chickpea genotypes contrasting in yield under terminal stress in the field were exposed to a controlled drought treatment in the glasshouse during reproduction. The ranking for relative seed yield (yield water stress/yield well watered) in the glasshouse conditions differed from the field. High seed yield under drought was linked to higher flower, pod and seed number, especially under mild water stress, while seed size was hardly affected by the drought treatment

The total area of the leaves on a plant is important in horticulture, but manually measuring it is tedious and destructive. Getting a computer to recognise and count leaves is difficult, so we have used statistical methods to relate leaf area to the variations in colour in an image. This has potential to be a big help for scientists developing and testing new crop cultivars.

pp. 1-8

Phosphorus is essential for plant growth but little is known about its acquisition in pasture grasses. We isolated a phosphate transporter gene from perennial ryegrass together with genes associated with mycorrhizal fungal colonisation and studied how these were affected by varying phosphate supply. This research will help understand phosphorus uptake in pasture grasses and how the relationship with symbiotic mycorrhizal fungi supports this.

Plants grown under flooding conditions display a large variation in aeration strategies in order to maintain suitable levels of oxygen to survive. We investigated these responses in three lowland grassland species, focusing on radial oxygen loss from roots, with different arrangement of aerenchyma. We found that hypoxia response as the oxygenation of roots depends on species and we discuss the physiological implications of the different responses.

Arbuscular mycorrhizal colonization elicits mycorrhizal-induced resistance (MIR), an enhanced pathogen defence response. To investigate the role of the oxylipin biosynthetic pathway in this phenomenon, we silenced lipoxygenases in normally AM colonized common bean roots and observed MIR impairment against a foliar pathogen. These findings provide novel insights into the onset of MIR, and will eventually be of great benefit to agriculture.

pp. 31-41

In rice (Oryza sativa L.), tiller angle – defined as the angle between the main culm and its side tillers – is one of the important factors involved in light use efficiency. Our analysis of a low stem starch mutant revealed suppression of starch synthesis in rice stems splays tiller angle due to gravitropic insensitivity but does not necessarily impact dry matter production. These findings provided new insights for rice breeding to improve plant architecture.

pp. 42-51

In the tropics, climate warming and intensified extreme weather events may lead to elevated peak temperatures transgressing the limit of thermal tolerance in plant leaves, causing permanent tissue damage. We demonstrate experimentally that light absorbed by leaves in excess of photosynthetic utilisation ameliorates thermal tolerance. Our results contradict the widespread notion that exposure of leaves to high light in combination with heat aggravates leaf damage.

The mechanisms for growth of Aspalathus linearis (Rooibos tea) in the nutrient-poor soils of the Core Cape subregion, and its response to combined addition of N and P, are not known. When addition of N induced low availability of P, the species increased partitioning of resources towards acquisition of P and also enhanced growth. Our findings show that plant growth is colimited by multiple resources.

Plants are generally assumed to become more sclerophyllous as precipitation declines – but not in West Africa where leaf mass per unit area actually declines with decreasing rainfall. Foliar potassium concentrations increase dramatically with increasing aridity, also differentiating ecotonal forest and savanna species. This suggests an important but as yet unidentified role for K as a modulator of tropical vegetation structure and function.

Potential advantages of highly mycotrophic foraging for the establishment of early successional pioneer plants on sand

Ingo Höpfner , Martina Friede , Stephan Unger and Wolfram Beyschlag
pp. 95-104

Nutrient uptake through symbiotic mycorrhizal fungi can be considered as an alternative to nutrient acquisition via roots. A comparison of both strategies in sand pioneer plants revealed that in ‘mycorrhiza strategists’ the enlargement of the absorptive surface area was clearly promoted and led to enhanced soil phosphorus depletion compared with ‘root strategists’. Thus, mycorrhizal fungi may be an important factor for the establishment of some plant species in nutrient poor sandy habitats.

Apart from water, nitrogen is also an important limiting factor in grape growing. The effects of nitrogen deficiency were investigated with 2-year-old Vitis vinifera cv. Shiraz plants grown in pots and exposed to various N supplies under well watered conditions. Primary axis elongation, leaf emergences on the primary and the secondary axes and lamina area expansion were significantly inhibited by nitrogen deficiency from flowering in an intensity-dependent manner.
