Drought tolerance involves mechanisms operating at different spatial and temporal scales, from rapid stomatal closure to maintenance of crop yield. We review how short-term mechanisms are controlled for stabilizing shoot water potential and how long-term processes have been constrained by evolution or breeding to fit into acclimation strategies for specific drought scenarios. These short- or long-term feedback processes participate in trade-offs between carbon accumulation and the risk of…

Crop adaptation to climate change as a consequence of long-term breeding

Looking forward, it is outlined how new approaches might complement conventional breeding to maintain and accelerate breeding progress, despite the challenges of climate change, as a prerequisite to sustainable future crop productivity.

Progress in understanding drought tolerance: from alleles to cropping systems

This special issue covers root dynamics, turgor management under desiccation, molecular responses to dehydration, impact of drought on plant development and seed abortion, and adjustment of traits to the most frequent patterns of drought.

The physiology of plant responses to drought

How engineering hormone signaling in specific cells and cellular domains can facilitate improved plant responses to drought is discussed and current knowledge and future questions central to the quest to produce high-yield, drought-resistant crops are explored.

Evolutionary Origins of Drought Tolerance in Spermatophytes

This work shows how this binary “drought tolerance/sensitivity” trait has evolved and discusses how incorporating this information into an evolutionary genomics framework could provide insights into the molecular mechanisms underlying extreme drought adaptations.

Genetic Analysis of Root-to-Shoot Signaling and Rootstock-Mediated Tolerance to Water Deficit in Tomato

Grafting commercial varieties onto selected rootstocks derived from S. pimpinellifolium provides a viable strategy to enhance drought tolerance in tomato by linkage of quantitative trait loci controlling these traits within four genomic regions.

Physiological adaptive traits are a potential allele reservoir for maize genetic progress under challenging conditions

Yield gains were linked to physiologically simple traits (plant phenology and architecture) which indirectly affected reproductive development and light interception in all studied environments, marked by significant genomic signatures of selection.

Detailed mechanisms and breeding approaches related to drought stress in cereals and specifically in sorghum are discussed.

Root-Related Genes in Crops and Their Application under Drought Stress Resistance—A Review

Crop growth and development are frequently affected by biotic and abiotic stresses. The adaptation of crops to stress is mostly achieved by regulating specific genes. The root system is the primary

Physiological Responses of Contrasting Maize (Zea mays L.) Hybrids to Repeated Drought

Overall, the recovery potential is underestimated in drought resistance under natural conditions, which includes periodic cycles of drought and rewatering, and should be considered in screening trials.

Drought and crop yield.

This review summarizes the effects of drought stress on crop plants and relates the dehydration-dependent yield penalty to the harvested organ and tissue and suggests ways to improve the ability to grow with less water.



Any trait or trait-related allele can confer drought tolerance: just design the right drought scenario.

Most traits associated with drought tolerance have a dual effect, positive in very severe scenarios and negative in milder scenarios, or the opposite trend, so spectacular results obtained in one drought scenario may have a limited interest for improving food security in other geographical areas with water scarcity.

Genome-Wide Analysis of Yield in Europe: Allelic Effects Vary with Drought and Heat Scenarios.

The approach showed a pattern of QTL effects expressed as functions of environmental variables and scenarios, allowing us to suggest hypotheses for mechanisms and candidate genes underlying each QTL, used for assessing the performance of genotypes and the contribution of genomic regions under current and future stress situations and to accelerate breeding for drought-prone environments.

Gene discovery in cereals through quantitative trait loci and expression analysis in water-use efficiency measured by carbon isotope discrimination.

Future efficient and effective breeding progress in cereals under targeted drought environments will come from the integrated knowledge of physiology and genomics.

Limited‐Transpiration Trait May Increase Maize Drought Tolerance in the US Corn Belt

Yield loss due to water deficit is ubiquitous in maize (Zea mays L.) production environments in the United States. The impact of water deficits on yield depends on the cropping system management and

Understanding plant responses to drought - from genes to the whole plant.

Attention is drawn to the perception and signalling processes (chemical and hydraulic) of water deficits, which are essential for a holistic understanding of plant resistance to stress, which is needed to improve crop management and breeding techniques.

Phenomics allows identification of genomic regions affecting maize stomatal conductance with conditional effects of water deficit and evaporative demand.

The combination of allelic effects, as affected by environmental conditions, accounted for the variability of stomatal conductance across a range of hybrids and environmental conditions and may contribute to genetic analysis and prediction ofStomatal control in diverse environments.
