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:

Advances in Drought Resistance of Rice
TL;DR: Recent developments in integrated approaches, such as genetics, breeding and resource management to increase rice yield and reduce water demand for rice production are discussed.

The Physiology and Proteomics of Drought Tolerance in Maize: Early Stomatal Closure as a Cause of Lower Tolerance to Short-Term Dehydration?
M. Benesova,D. Holá,Lukáš Fischer,Petr Jedelský,František Hnilička,N. Wilhelmová,O. Rothová,M. Kočová,Dagmar Procházková,Jana Honnerová,Lenka Fridrichová,Helena Hniličková +11 more
TL;DR: It is proposed that the hypersensitive early stomatal closure in the sensitive genotype leads to the inhibition of photosynthesis and, subsequently, to a less efficient synthesis of the protective/detoxification proteins that are associated with drought tolerance.

Effect of drought on yield variability of key crops in Czech Republic
Petr Hlavinka,Miroslav Trnka,Daniela Semerádová,Martin Dubrovský,Martin Dubrovský,Zdeněk Žalud,Martin Možný +6 more
TL;DR: The study proved that a severe drought spell during the sensitive period of vegetative season does have a quantifiable negative effect, even within more humid regions and drought is one of the key causes of interannual yield variability.

Increasing influence of heat stress on French maize yields from the 1960s to the 2030s
Ed Hawkins,Thomas E. Fricker,Andrew J. Challinor,Christopher A. T. Ferro,Chun Kit Ho,Tom M. Osborne +5 more
TL;DR: It is concluded that, to offset the projected increased daily maximum temperatures over France, improved technology will need to increase base level yields by 12% to be confident about maintaining current levels of yield for the period 2016–2035; the current rate of yield technology increase is not sufficient to meet this target.
Journal ArticleDOI
Aquaporin-mediated increase in root hydraulic conductance is involved in silicon-induced improved root water uptake under osmotic stress in Sorghum bicolor L.
TL;DR: It is demonstrated that silicon-enhanced root hydraulic conductance through up-regualtion of aquaporin gene expression resulted in improved root water uptake under osmotic stress in sorghum.

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.

The analysis of adaptation in a plant-breeding programme
K.W. Finlay,G.N. Wilkinson +1 more
TL;DR: Varieties from particular geographic regions of the world showed a similarity in type of adaptation, which provides a useful basis for plant introduction and breeding.
