TLDR
Breeders are asked to blend together all knowledge on the traits sustaining yield under drought and to accumulate the most effective QTLs and/or transgenes into elite genotypes without detrimental effects on yield potential, which will lead to new cultivars with high yield potential and high yield stability, that will result in superior performance in dry environments.About:

Genetic Screening for Mutants with Altered Seminal Root Numbers in Hexaploid Wheat Using a High-Throughput Root Phenotyping Platform.
Oluwaseyi Shorinola,Oluwaseyi Shorinola,Ryan Kaye,Guy Golan,Zvi Peleg,Stefan Kepinski,Cristobal Uauy +6 more
TL;DR: The potential to use the sequenced wheat mutant population as a forward genetic resource to uncover novel variation in agronomic traits, such as seminal root architecture, is highlighted.

Water deficit‐induced changes in transcription factor expression in maize seedlings
Candace M. Seeve,Candace M. Seeve,In-Jeong Cho,Leonard B. Hearne,Gyan Srivastava,Trupti Joshi,Dante O. Smith,Robert E. Sharp,Melvin J. Oliver +8 more
TL;DR: TFs with stress-induced increased abundance in primary root tips that likely regulate root growth responses to water deficits, possibly as part of abscisic acid and/or auxin-dependent signaling pathways are revealed.

Patenting Drought Tolerance in Organisms
TL;DR: This review summarizes some of the recent published patents related to drought tolerance genes and their use.
Journal ArticleDOI
Physiological, Hormonal and Metabolic Responses of two Alfalfa Cultivars with Contrasting Responses to Drought.
TL;DR: The results showed an intra-specific response to drought at physiological and metabolic levels in the two alfalfa cultivars studied, suggesting that this cultivar-specific performance is linked to Asn accumulation and its consequent N-feedback nitrogenase inhibition.

Stability Parameters for Comparing Varieties
S. A. Eberhart,W. A. Russell +1 more
TL;DR: The model, Yij = μ1 + β1Ij + δij, defines stability parameters that may be used to describe the performance of a variety over a series of environments to see whether genetic differences could be detected.
Journal ArticleDOI
Understanding plant responses to drought — from genes to the whole plant
TL;DR: 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.
Journal ArticleDOI
Plant responses to drought, salinity and extreme temperatures: towards genetic engineering for stress tolerance
TL;DR: The present review summarizes the recent advances in elucidating stress-response mechanisms and their biotechnological applications and examines the following aspects: regulatory controls, metabolite engineering, ion transport, antioxidants and detoxification, late embryogenesis abundant (LEA) and heat-shock proteins.
