Increasing nitrogen supply stimulates phosphorus acquisition mechanisms in the fynbos species Aspalathus linearis 
Pravin M. Maistry, A. Muthama Muasya, Alex J. Valentine and Samson B. M. Chimphango

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.

Light-stimulated heat tolerance in leaves of two neotropical tree species, Ficus insipida and Calophyllum longifolium 
G. Heinrich Krause, Klaus Winter, Barbara Krause and Aurelio Virgo

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.

Photoperiodic variations induce shifts in the leaf metabolic profile of Chrysanthemum morifolium 
Katrine Heinsvig Kjaer, Morten Rahr Clausen, Ulrik Kræmer Sundekilde, Bent Ole Petersen, Hanne Christine Bertram and Carl-Otto Ottosen

Diurnal patterns in leaf primary metabolites are complex, and vary in relation to light intensity and photoperiodic variation. We demonstrate a coupling between diurnal patterns in leaf metabolites and leaf expansion, and that diurnal patterns of some metabolites are not affected by photoperiodic variation. The results enlighten the plasticity of primary metabolism and leaf expansion in an ever-changing environment.

Phenotyping novel stay-green traits to capture genetic variation in senescence dynamics 
John T. Christopher, Mathieu Veyradier, Andrew K. Borrell, Greg Harvey, Susan Fletcher and Karine Chenu

Stay-green crops retain green leaves longer after anthesis which can improve yield, particularly under water-limitation. We describe a new method to monitor and analyse the dynamics of canopy greenness with improved detection and interpretation of genotypic variation in stay-green. It is anticipated that selection for the identified novel stay-green traits will enhance genetic progress toward high-yielding cultivars.

Automated estimation of leaf area development in sweet pepper plants from image analysis 
Graham W. Horgan, Yu Song, Chris A. Glasbey, Gerie W. A. M. van der Heijden, Gerrit Polder, J. Anja Dieleman, Marco C. A. M. Bink and Fred A. van Eeuwijk

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.

Response of floret fertility and individual grain weight of wheat to high temperature stress: sensitive stages and thresholds for temperature and duration 
P. V. Vara Prasad and Maduraimuthu Djanaguiraman

High temperature (HT) stress causes significant yield losses in wheat. The two periods most sensitive to short episodes of HT stress were identified as gamete development and fertilisation. Short episodes (5 days) of mean temperatures >24°C decreased floret fertility. Increasing duration (from 2 to 30 days) of HT stress (mean temperature of 30°C) linearly decreased floret fertility and individual grain weight.

Seedling mortality during biphasic drought in sandy Mediterranean soils 
Stephen M. Benigno, Kingsley W. Dixon and Jason C. Stevens

Increasing drought events may further exacerbate the currently high seedling mortality patterns observed in restoration programs. This paper demonstrates a catastrophic decrease in physiological resilience of three Mediterranean tree species during the seedling establishment phase to successive droughts. An understanding of plant functional requirements through critical development stages will enable restoration practitioners to overcome high failure rates and improve biodiversity outcomes generally.

Rhizobium-induced elevation in xylem cytokinin delivery in pigeonpea induces changes in shoot development and leaf physiology 
Jean W. H. Yong, D. Stuart Letham, S. Chin Wong and Graham D. Farquhar

Pigeon pea, inoculated with Rhizobium strain IC3342, offers a novel system to study the role of xylem cytokinin in shoot development. With a 3-fold elevation in xylem cytokinin delivery to the shoot, various aspects of leaf physiology and shoot development were altered especially lateral bud outgrowth. Overall, xylem sap cytokinin appears to act as a pleiotropic regulator of plant development.

Two potato (Solanum tuberosum) varieties differ in drought tolerance due to differences in root growth at depth 
Jaime Puértolas, Carlos Ballester, E. David Elphinstone and Ian C. Dodd

Since potato crops often require supplemental irrigation, selecting drought-tolerant varieties might help save water. We tested the importance of root biomass growth by comparing the physiology of two varieties with contrasting drought tolerance. When root growth was constrained, there were no genotypic differences in shoot physiological responses as the soil dried. Under field conditions, the drought-tolerant variety had greater root growth and maintained yield with less irrigation by better accessing moist soil layers deeper in the profile.

Post–flood nitrogen and basal phosphorus management affects survival, metabolic changes and anti-oxidant enzyme activities of submerged rice (Oryza sativa) 
Priyanka Gautam, Banwari Lal, Rajagounder Raja, Mirza Jaynul Baig, Deepika Haldar, Liza Rath, Mohammad Shahid, Rahul Tripathi, Sangita Mohanty, Pratap Bhattacharyya and Amaresh Kumar Nayak

Post-flood nitrogen and basal phosphorus application were evaluated on submergence tolerance of rice under clear and turbid water with submergence tolerant and susceptible cultivars. Urea spray and basal phosphorus improved survival, chlorophyll, non-structural carbohydrates and reduced shoot elongation and ethylene even in turbid water. Nutrient management options can provide opportunities for better survival and establishment of submerged rice, helping farmers to cope with the existing problems in flood-prone areas.

Functional characterisation of a WRKY transcription factor of wheat and its expression analysis during leaf rust pathogenesis 
Dhananjay Kumar, Anjali Kapoor, Dharmendra Singh, Lopamudra Satapathy, Ashwini Kumar Singh, Manish Kumar, Kumble Vinod Prabhu and Kunal Mukhopadhyay

The WRKY TFs has been a subject of intense research; however, their functional analysis in crops like wheat is still lacking. The molecular structure of a WRKY gene JX028549 was revealed and its spatio-temporal expression showed upregulation in response to the leaf rust pathogenesis. The results contribute towards understanding the structure and function of a wheat WRKY TF that can be used as a candidate gene to improve biotic stress tolerance.

Vigour reduction in girdled peach trees is related to lower midday stem water potentials 
Sergio Tombesi, Kevin R. Day, R. Scott Johnson, Rebecca Phene and Theodore M. DeJong

Trunk girdling (horticultural practice used to increase fruit size) reduces vegetative shoot growth although there appears to be higher availability of carbohydrates above the girdle in girdled trees. This research indicates that early spring scaffold girdling decreased stem water potential above the girdle suggesting that early spring girdling not only influences phloem flow (that is interrupted by girdling) but also decreases xylem flow. The decreased stem water potentials appear to be directly related to reductions in vegetative shoot growth and explain why early spring girdling reduces shoot growth. It is hypothesized that early spring girdling affects xylem flow because the girdling process interrupts cambial activity and the production of new xylem however girdling may also influence root activity.

Genotypic differences in deep water extraction associated with drought tolerance in wheat 
Eric S. Ober, Peter Werner, Edward Flatman, William J. Angus, Peter Jack, Lucy Smith-Reeve and Chris Tapsell

Accessing sufficient soil moisture is vital to maintaining yield during droughts, but to produce improved varieties for such conditions breeders must be able to identify lines with deep root systems. We found that wheat varieties differed in the ability to mine water from deep soil layers, which was related to drought tolerance and without significant yield penalty. These findings and the methods employed should help validate new candidate lines to realise greater breeding progress for water limited conditions.

Drought tolerances of three stem-succulent halophyte species of an inland semiarid salt lake system 
Victoria A. Marchesini, Chuanhua Yin, Timothy D. Colmer and Erik J. Veneklaas

Tecticornia species are dominant in saline habitats differing in the frequency and intensity of drought and flooding. In controlled conditions, the comparative response of three species to drying soil was remarkably similar, despite their distribution at opposite ends of a water availability gradient. Combined osmotic and matrix components of soil water potential during drought stress in drying saline soils have important implications for the understanding of physiological tolerance mechanisms and habitat requirements of salt lake halophytes.

Brachypodium distachyon: a model species for aluminium tolerance in Poaceae 
Roberto Contreras, Ana M. Figueiras, Francisco J. Gallego and Cesar Benito

Aluminium (Al) toxicity is the main abiotic stress limiting plant productivity in acidic soils. Brachypodium distachyon (Bd) is a good model species for Al tolerance in Poaceae. The exudation of organic acids was involved in the Al tolerance of Brachypodium. An insertion was present in the promoter region of BdALMT1 (Al-activated malate transporter) gene of tolerant diploid and allotetraploid plants.

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.

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.

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.

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.

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.

Crop yield components – photoassimilate supply- or utilisation limited-organ development? 
blank image
John W. Patrick and Kim Colyvas
pp. 893-913

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.

Responses of rice to Fe2+ in aerated and stagnant conditions: growth, root porosity and radial oxygen loss barrier 
blank image
Jenjira Mongon , Dennis Konnerup , Timothy D. Colmer and Benjavan Rerkasem
pp. 922-929

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.

Saving and sustaining productivity of rice under water limited conditions 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
pp. 940-953

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.

pp. 954-962

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.

Genotype-dependent influence of night-time vapour pressure deficit on night-time transpiration and daytime gas exchange in wheat 
blank image
Rémy Schoppach , Elodie Claverie and Walid Sadok
pp. 963-971

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.

Coffee productivity and survival are posed at risk by ongoing climate changes.

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).
