Modelling the effect of plant water use traits on yield and stay-green expression in sorghum 
Jana Kholová, Tharanya Murugesan, Siva Sakhti, Srikanth Malayee, Rekha Baddam, Graeme L. Hammer, Greg McLean, Santosh Deshpande, C. Thomas Hash, Peter Q. Craufurd and Vincent Vadez

Post-rainy sorghum production, the source of livelihood in developing countries, is being decimated by drought. Water use traits linked to stay-green expression were modelled and are predicted to have positive effect on sorghum production in target groups of environments in India. Trait-based breeding approach could enhance the production in target environments world-wide.

Do wide crowns in arid woodland trees reflect hydraulic limitation and reduction of self-shading? 
Martín Escoto-Rodríguez, José M. Facelli and Jennifer R. Watling

In arid lands many trees develop broad crowns that affect many ecological interactions, but how that form is acquired is unresolved. We measured crown shape and carbon isotope ratios. We found that upper branches suffered more water stress than laterally spreading branches, and that lower branches were affected by self-shading. When lower and upper branches are stressed, lateral spreading at middle crown become the best alternative for growth. These results advance our understanding of crown development in trees.

Early detection of Psa infection in kiwifruit by means of infrared thermography at leaf and orchard scale 
Wouter H. Maes, Peter E. H. Minchin, William P. Snelgar and Kathy Steppe

Pseudomonas syringae pv. actinidiae (Psa) the causal agent of bacterial canker of kiwifruit, has become a worldwide threat for the kiwifruit industry. In this work, we show that Psa can be detected at early stages of infection both at leaf and canopy scale using infrared thermography. At leaf scale, this method will be able to assist fundamental research of infection mechanisms; at canopy scale, the method could be used to identify regions of Psa-infection to be pruned out to prevent further devastating spread of the disease.

Genomics-assisted breeding for drought tolerance in chickpea 
Mahendar Thudi, Pooran M. Gaur, Lakshmanan Krishnamurthy, Reyazul R. Mir, Himabindu Kudapa, Asnake Fikre, Paul Kimurto, Shailesh Tripathi, Khela R. Soren, Richard Mulwa, Chellapilla Bharadwaj, Subhojit Datta, Sushil K. Chaturvedi and Rajeev K. Varshney

For enhancing precision and efficiency in chickpea breeding especially for drought tolerance, large-scale genomic resources have been developed. These resources together with genetics and physiological approaches facilitated dissecting complex phenomenon of drought tolerance. Marker-assisted backcrossing has generated several lines with enhanced yield under rained conditions. Such advances have made it possible to deploy genomics-assisted breeding for drought tolerance in chickpea.

Balancing crop yield and water productivity tradeoffs in herbaceous and woody crops 
Elías Fereres, Francisco Orgaz, Victoria Gonzalez-Dugo, Luca Testi and Francisco J. Villalobos

Trade-offs between crop yield and water productivity (WP; yield divided by water use) are important in water-limited situations. Genetic improvement for WP generally has yield trade-offs, whereas management measures devised to improve WP tend to enhance yield as well. In contrast to the behaviour of the major herbaceous crops, WP increases in woody crops in response to water stress, facilitating the application of deficit irrigation strategies.

Genetic variability and identification of quantitative trait loci affecting plant growth and chlorophyll fluorescence parameters in the model legume Medicago truncatula under control and salt stress conditions 
Sarah Exbrayat, Georges Bertoni, Mohamad Reza Naghavie, Ali Peyghambari, Mounavar Badri and Frédéric Debelle

Salinity is one of the major stresses that limits crop production worldwide and affects most physiological activities in plants. An experiment was undertaken to determine genetic variability in Medicago truncatula, and to identify quantitative trait loci (QTLs). Nineteen QTLs were identified under 100 mm salt stress conditions. The results should be helpful information for further functional analysis of salt tolerance in M. truncatula.

Quantitative trait locus mapping of the transpiration ratio related to preflowering drought tolerance in sorghum (Sorghum bicolor) 
Mohankumar H. Kapanigowda, William A. Payne, William L. Rooney, John E. Mullet and Maria Balota

Improving the ratio of biomass produced to water transpired is one way to improve water productivity, which is necessary to increase production to feed 9.6 billion by 2050. The study aimed to understand the genetic basis of the transpiration ratio (A : E), and the genetic and physiological determinants of water use in sorghum. Favourable alleles for A : E traits related to preflowering drought tolerance along with stay-green may help develop more drought-tolerant sorghum cultivars.

Individual and combined effects of transient drought and heat stress on carbon assimilation and seed filling in chickpea 
Rashmi Awasthi, Neeru Kaushal, Vincent Vadez, Neil C. Turner, Jens Berger, Kadambot H. M. Siddique and Harsh Nayyar

Droughts are often accompanied by rising temperatures, severely affecting seed filling. The effects of these stresses, individually or combined, on biochemical processes related to seed filling was investigated in chickpea genotypes having contrasting sensitivity to heat and drought stress. Leaf photosynthetic function and sucrose metabolism in seeds were severely disrupted, especially by combined stress, resulting in reductions in seed weight and yield. A drought-tolerant genotype appeared to have partial cross-tolerance to heat stress.

Review on shape formation in epidermal pavement cells of the Arabidopsis leaf 
Eveline Jacques, Jean-Pierre Verbelen and Kris Vissenberg

Epidermal pavement cells appear with a fascinating irregular wavy shape in the Arabidopsis thaliana leaf. This review addresses the possible biomechanical benefits of this cell shape over other organisations as well as the biomechanical accomplishment of shape and refers to the cell wall and cytoskeletal involvement herein. A current model for pavement cell development integrating genetic and biochemical regulatory pathways is discussed, but remaining questions and pitfalls are put forward.

Crop yield components – photoassimilate supply- or utilisation limited-organ development? 
John W. Patrick and Kim Colyvas

Sucrose production, transport and utilisation are central processes determining crop yield. Their relative quantitative contributions (limitations) to yield are a core plank to direct strategies for crop improvement. Using published responses of a selection of crop species to elevated carbon dioxide concentrations, our analysis demonstrates that numbers in particular and, to a lesser extent potential sizes, of harvested organs are sucrose production/transport (i.e. supply) limited whereas filling these organs is sucrose utilisation limited. These conditions apply across a range of harvested organ types including storage stems and roots, fleshy fruits, grains and tubers.

Mucilage exudation facilitates root water uptake in dry soils 
Mutez A. Ahmed, Eva Kroener, Maire Holz, Mohsen Zarebanadkouki and Andrea Carminati

As roots take up water and the soil dries, water depletion is expected to occur near the root surface, ultimately limiting root water uptake. By exuding mucilage, a gel that can hold much water, roots keep the soil in their vicinity wet and can better extract water from dry soils. Mucilage exudation seems to be an optimal plant trait that favours the capture of water during drought.

When smaller is better: leaf hydraulic conductance and drought vulnerability correlate to leaf size and venation density across four Coffea arabica genotypes 
Andrea Nardini, Eele Õunapuu-Pikas and Tadeja Savi

Coffee productivity and survival are posed at risk by ongoing climate changes. Leaf hydraulic capacity and drought vulnerability are key functional traits influencing plant performance under drought stress conditions. Coffee genotypes with small leaves and high vein length per unit leaf area displayed higher leaf hydraulic efficiency, gas exchange rates and resistance to drought-induced hydraulic dysfunction, with respect to large-leaf cultivars.

Genotype-dependent influence of night-time vapour pressure deficit on night-time transpiration and daytime gas exchange in wheat 
Rémy Schoppach, Elodie Claverie and Walid Sadok

The amount of water lost by crops during the night through transpiration can represent a substantial fraction of the daytime water loss, but no efforts have been made to identify possible drought tolerance strategies resulting from such responses. Here we report substantial cultivar-dependent night-time transpirational water losses in wheat, which are dependent on nocturnal evaporative conditions and are strongly related to daytime water loss. These findings open new possibilities for breeding drought-tolerant cultivars based on night-time water use.

Root traits and cellular level tolerance hold the key in maintaining higher spikelet fertility of rice under water limited conditions 
Bheemanahalli R. Raju, Beerasandra R. Narayanaswamy, Malagondanahalli V. Mohankumar, Kambalimath K. Sumanth, Mavinahalli P. Rajanna, Basavaiah Mohanraju, Makarla Udayakumar and Madavalam S. Sheshshayee

Saving and sustaining productivity of rice under water limited is essential to feed the growing population. Better water acquisition coupled with higher cellular level tolerance maintained significantly higher spikelet fertility and thus emphasised the relevance of combining these for improving field level tolerance of rice to water limitation. Such lines can be exploited in breeding to develop superior trait pyramided cultivars. Aerobic cultivation of rice saves water but reduced spikelet fertility causes significant yield loss. We demonstrated that superior roots traits when combined with higher cellular level tolerance maintained higher spikelet fertility and yield. The identified trait donor genotypes can be exploited to develop trait pyramided aerobic cultivation worthy cultivars.

Bark and woody tissue photosynthesis: a means to avoid hypoxia or anoxia in developing stem tissues 
Christiane Wittmann and Hardy Pfanz

In plants, specialised systems for O2 delivery as in animals are lacking. Plant cells are thus frequently challenged with limited oxygen supply. Under illumination, bark and woody tissue photosynthesis rapidly increased plant internal oxygen concentrations and thereby counteracted localised oxygen deficiency (hypoxia). Beneath its role in plant carbon economy, bark and woody tissue photosynthesis may also be important for preventing low-oxygen limitations of respiration in these dense and metabolically active tissues.

Responses of rice to Fe2+ in aerated and stagnant conditions: growth, root porosity and radial oxygen loss barrier 
Jenjira Mongon, Dennis Konnerup, Timothy D. Colmer and Benjavan Rerkasem

Lowland rice grows in flooded soils which often have low redox potential and high soluble iron (Fe2+), so the effects of Fe2+ concentrations on growth, root porosity and barrier to radial oxygen loss induction were assessed in aerobic and in stagnant conditions. High Fe2+ (0.72 mM) resulted in increased porosity and barrier induction in roots of rice in aerated conditions, whereas in stagnant conditions these root aeration traits were already induced even without addition of high Fe2+. Barrier induction and root aeration would contribute to Fe2+ tolerance in rice.

Alterations in stem sugar content and metabolism in sorghum genotypes subjected to drought stress 
Hilal A. Qazi, Pinnamaneni Srinivasa Rao, Akanksha Kashikar, Penna Suprasanna and Sujata Bhargava

Sorghum plants store sugar in their stems, besides yielding grain, making it an attractive crop for food and biofuel production. The role of stem sugar accumulation in helping plants cope with drought has been investigated. Stems serve as independent sinks for photoassimilates in addition to the panicle in some genotypes; in others, the stored stem sugars appear to be mobilised to the panicle to augment grain yields in drought-stressed plants.

Genomics for drought resistance – getting down to earth 
Abraham Blum

This Perspective paper inquires why, after 20 years of extensive research into the genomics of drought resistance, there are hardly any transgenic genetically modified drought-resistant crop cultivar on the market to date. An important reason is that often, the drought stress simulations and testing methods used in genomics are at fault. Guidelines for relevant drought stress physiological methods in genomics are suggested.

Partial root zone drying exerts different physiological responses on field-grown grapevine (Vitis vinifera cv. Monastrell) in comparison to regulated deficit irrigation 
Pascual Romero, Juan Gabriel Pérez-Pérez, Francisco M. del Amor, Adrián Martinez-Cutillas, Ian C. Dodd and Pablo Botía

High irrigation volumes applied to the wet part of the root system are critical to successfully implement partial root zone drying irrigation (PRI) to improve vine performance compared to regulated deficit irrigation under semiarid conditions. Physiological responses induced by PRI were due to both the placement of irrigation and the volume of water. Thresholds and optima of soil water content in wet and dry root zones were established.

Soil water-holding capacity mediates hydraulic and hormonal signals of near-isohydric and near-anisohydric Vitis cultivars in potted grapevines 
Sara Tramontini, Johanna Döring, Marco Vitali, Alessandra Ferrandino, Manfred Stoll and Claudio Lovisolo

The ecophysiological behaviour of grapevine cultivars in response to drought is influenced by the soil conditions and by the plant genotype. These two components interact through a complex of hydraulic and hormonal signal exchanges occurring between roots and leaves. Our work highlights the differences in these signals observed in a near-isohydric and a near-anisohydric grapevine cultivars on two soil substrates with different textures, causing different dynamics of water deprivation during an imposed increasing water stress.

Physiological basis of salt stress tolerance in rice expressing the antiapoptotic gene SfIAP 
Thi My Linh Hoang, Brett Williams, Harjeet Khanna, James Dale and Sagadevan G. Mundree

Salinity is a growing problem worldwide that causes a significant reduction in crop yields. We have addressed this problem by manipulating the programmed cell death pathways in rice, resulting in enhanced salt stress tolerance. The implication is that farmers could grow rice containing such a trait in environments where salinisation of the soil exists, thereby addressing food security needs.

Retrotransposons (RTs) are major components of most eukaryotic genomes. Molecular markers play an essential role in all aspects of genetics and genomics, and RTs represent a powerful tool compared with other molecular and morphological markers. Here, we review the utility of some PCR retrotransposon-based molecular markers, including inter-primer binding sequence (IPBS), sequence-specific amplified polymorphism (SSAP), retrotransposon-based insertion polymorphism (RBIP), inter retrotransposon amplified polymorphism (IRAP) and retrotransposon-microsatellite amplified polymorphism (REMAP).

K+ nutrition plays a critical role in plants under salinity. We have characterised a potassium transporter, SsHKT1;1, from the euhalophyte Suaeda salsa L. and provide molecular and physiological evidence that it plays pivotal role in salt tolerance in halophytes such as S. salsa. These results will pave the way for improving the salt tolerance of crops by genetic engineering.

Cytosolic alkalisation and nitric oxide production in UVB-induced stomatal closure in Arabidopsis thaliana

Xiao-Min Ge , Yan Zhu and Jun-Min He
pp. 803-811

Although stomatal movement is regulated by UVB radiation, the underlying mechanism is unclear. The data presented here show that both cytosolic alkalisation and NO participate in UVB-induced stomatal closure, and indicate that NO generation is elicited following cytosolic alkalisation and regulates cytosolic alkalisation via feedback. These findings help us gain further insights into UVB signalling, and the interaction of cytosolic alkalisation and NO production during multiple stimuli-triggered signalling in plants.

Water uptake and redistribution during drought in a semiarid shrub species 
blank image
Iván Prieto , Francisco I. Pugnaire and Ronald J. Ryel
pp. 812-819

In arid systems, plants die during long drought periods and their performance may depend on their use of episodic rain events. Water from these events is often rapidly lost to evaporation but plants may draw it to deep soil layers, storing it to prevent evaporation and to allow for an efficient use. This mechanism supports longer plant survival and may be of great relevance in dry environments.

Keith J. Bloomfield , Graham D. Farquhar and Jon Lloyd
pp. 820-832

Tropical forests play a vital role in the global carbon cycle and there is growing evidence that here, phosphorus (rather than nitrogen) may be the key nutrient limiting photosynthetic rates. In a greenhouse study of Australian tropical tree species, we found that phosphorus limitation reduced photosynthetic capacity and altered nitrogen use. The results underline the importance of phosphorus effects for future studies of tropical forest productivity.

Leaf shape influences spatial variation in photosynthetic function in Lomatia tinctoria 
blank image
Andrea Leigh , Ross Hill and Marilyn C. Ball
pp. 833-842

It is not yet known why leaf shape varies so widely among different plant species, but plant biologists suspect one reason might relate to different adaptations for optimal water delivery to and within leaves. This study showed that in response to extreme short-term water stress, photosynthetic function was more spatially uniform in broad-shaped leaves, despite the lower density of water conducting veins to support photosynthesis, relative to narrow-shaped leaves. These findings suggest that the spatial arrangement of veins alone is partially responsible for different stress responses in contrasting leaf shapes.

We tested whether growth of Agave angustifolia is reduced at high night temperatures as has been reported for many other succulents from habitats with pronounced day-night temperature variations. The persistence of appreciable rates of water-conserving dark CO2 fixation even at high day and night temperatures demonstrates the potential of this Agave, and perhaps others like it, for biomass production in seasonally-dry landscapes.

The dynamics of recently assimilated carbon are a key driver of the carbon budget of terrestrial ecosystems and of their response to global change. Our study shows that belowground transfer of photosynthates is related to plant physiological controls, which, unlike environmental controls, are still poorly characterised. Our study contributes to improve the understanding of the dynamics of carbon allocation and isotopic signatures in terrestrial ecosystems.

pp. 860-873

Selection of crops under saline conditions has been notoriously difficult. Simplified platforms and stress scenarios are used too often to evaluate the salt tolerance and to extrapolate to real field conditions. We evaluated growth platforms and stress scenarios and conclude that a combined salinity + drought stress scenario and a reliable growth platform are of utmost importance in screening for salt tolerance.

Accurate quantification of crop water use is needed for efficient irrigation management in dry growing regions.

This technology has potential use in irrigation management and research settings.

pp. 884-891

Fruiting in many tree species is known to impact productivity in subsequent years. In this research we tested whether almond fruit competes with leaves for nitrogen and hypothesised how this would impact leaf carbon assimilation rates through the season. The results showed that almond cannot supply sufficient nitrogen simultaneously to fully satisfy the demands of leaves and fruits born in the same spur (principal bearing structure of almond trees).
