We have analysed daily patterns of leaf elongation rate (LER) in large data sets with 318 genotypes placed naturally fluctuating temperature and evaporative demand, examined the effect targeted alleles on these patterns. The method consisted, firstly, expressing per unit thermal time, so it became independent; secondly, a joint analysis diurnal fluctuations micrometeorological conditions several experiments, finally, comparison between groups possessing alleles. (1) Conditions for using time...
The slow-wilting soybean [Glycine max (L.) Merr.] genotype, PI 416937, exhibits a limiting leaf hydraulic conductance for transpiration rate (TR) under high vapour pressure deficit (VPD). This genotype has constant TR at VPD greater than 2 kPa, which may be responsible its drought tolerance as result of soil water conservation. However, the exact source limitation between symplastic and apoplastic flow in conditions are not known 416937. A comparison was made response to aquaporin (AQP)...
Efficient breeding of drought-tolerant wheat (Triticum spp.) genotypes requires identifying mechanisms underlying exceptional performances. Evidence indicates that the line RAC875 is water-use conservative, limiting its transpiration rate (TR) sensitivity to increasing vapour pressure deficit (VPD), thereby saving soil water moisture for later use. However, physiological basis response remains unknown. The involvement leaf and root developmental, anatomical hydraulic features in regulating...
Atmospheric vapor pressure deficit (VPD) is a key component of drought and has strong influence on yields. Whole-plant transpiration rate (TR) response to increasing VPD been linked tolerance in wheat, but because its challenging phenotyping, genetic basis remains unexplored. Further, the control other traits daytime TR such as leaf area, stomata densities – more recently nocturnal unknown. Considering presence wheat phenology genes that can interfere with tolerance, aim this investigation...
The beginning of the ‘Arab Spring’ in 2011, a regional revolution which started Tunisian city Sidi Bouzid late 2010, occurred part as result drought-triggered high wheat prices, past led to ‘bread riots’ across several Middle East and North Africa (MENA) nations. Here we present, for first time, an analysis possible amelioration yield loss greater stability bread supply resulting from incorporation putative drought-tolerant traits into cultivars grown Tunisia. To this end, used simulation...
The water deficit experienced by crops is a function of atmospheric demand (vapor pressure deficit) and soil supply over the whole crop cycle. We summarize typical transpiration response patterns to drying sensitivity plant hydraulic traits. explain using soil-plant framework. In both cases drying, stomatal closure triggered limitations in conductance. However, traits impacting differ between two processes act at different time scales. A low conductance triggers an earlier restriction during...
Simulation studies have demonstrated that the existence of a limitation on maximum transpiration rate (TR) at high air vapor pressure deficit (VPD) in water‐limited conditions could result significant yield increases. A genotype soybean [ Glycine max (L.) Merr.] (PI 416937) has been identified both with slow‐wilting phenotype field and limited TR above VPD breakpoint (BP) 2 kPa. Until now, there no full documentation any other restriction VPD. The objective this study was to extend...
In crop plants, accumulating evidence indicates non-marginal night-time transpiration (TRNight) that is responsive to environmental conditions, especially in semiarid areas. However, the agronomical advantages resulting from such phenomenon remain obscure. Recently, drought-tolerance strategies directly stemming daytime TR (TRDay) responses vapour pressure deficit VPD (VPDDay) were identified wheat (Triticum spp.), but existence of similar TRNight response (VPDNight) remains be investigated,...
Abstract Iron deficiency is an important soybean [ Glycine max (L.) Merr.] nutrient that easily identified by interveinal chlorosis of the leaves and reduced plant growth, both which lead to yield reductions. Research in iron often segmented into studies on soil characteristics, microbe interactions, specific phenotypes, or genetics efficiency. Joining these areas research a comprehensive literature review will advance our understanding physiology help bridge known (IDC) resistance loci with...
Abstract Increasing wheat yields is critical to meet the demands of a growing population and ensure socioeconomic stability. Rising photosynthesis being proposed as promising avenue increase yields, but evidence for this conflicting across studies. To test viability hypothesis, here we report systematic quantitative literature review examining association between historic yield increases due breeding that occurred over 129 years (1890–2019) globe light‐saturated ( A sat ) 273 commercial...
Abstract Recent evidence pointed to functional stomata on the abaxial side of barley leaf sheaths. However, extent which variation in sheath densities (SD SheathAb) drives canopy water use and whether it has a genetic basis remains unknown. To address this, we phenotyped, twice, mapping population consisting 156 genotypes (936 plants) for their adaxial blade SDs, whole-plant transpiration rate (TR) conductance (Gs). Across four SD traits, SheathAb exhibited highest repeatability (0.73) was...
Abstract Historically, wheat yields in drought‐prone Australian environments have been consistently increasing for over a century. There is currently an agreement that approximately half of increase attributable to breeding programmes, but their physiological basis remains poorly documented. In this investigation, we hypothesized limited whole‐plant transpiration rate ( TR ) under high atmospheric vapour pressure deficit VPD could result advantageous water conservation and crop yield south...
