Abstract Understanding how wheat ( Triticum aestivum L.) plants under high temperature (HT) regulate lipid composition is critical to developing climate‐resilient varieties. We measured 165 glycerolipids and sterol derivatives optimum day night temperatures in leaves using electrospray ionization‐tandem mass spectrometry. Levels of polar fatty acyl chain unsaturation were lower both heat‐tolerant genotype Ventnor susceptible Karl 92 HT, compared with temperature. The was predominantly...

Understanding the adaptive changes in wheat pollen lipidome under high temperature (HT) stress is critical to improving seed set and developing HT tolerant varieties. We measured 89 lipid species optimum day and/or night temperatures using electrospray ionization-tandem mass spectrometry plants. The had a distinct composition compared with that of leaves. Unlike leaves, 34:3 36:6 dominated extraplastidic phospholipids conditions. most HT-responsive lipids were phospholipids,...
Drought stress has been identified as the major environmental factor limiting soybean [Glycine max (L.) Merr.] yield worldwide. Current breeding efforts in largely focus on identifying genotypes with high seed and drought tolerance. Water use efficiency (WUE) that results greater per unit rainfall is an important parameter determining crop yields many production systems, often related Even though roots are plant organs perceive respond to stress, their utility improving WUE under different...
Identifying lipids that experience coordinated metabolism during heat stress would provide information regarding lipid dynamics under conditions and assist in developing heat-tolerant wheat varieties. We hypothesized co-occurring lipids, which are up-regulated or down-regulated together through time stress, represent groups can be explained by metabolism. Wheat plants (Triticum aestivum L.) were subjected to 12 days of high day and/or night temperature followed a 4-day recovery period....
Wheat (Triticum aestivum L.) is the most important crop in world terms of area harvested and second food developing after rice.To meet increased demand exploding population by 2050, wheat production needs to increase 60%.However, yields are currently limited several environmental stresses, high temperature stress a major one among them.This review focuses on impact plants traits associated with tolerance which would help formulate management strategies for yield improvement under breeding...
Heat-induced changes in lipidome and their influence on stress adaptation are not well-defined plants. We investigated if lipid metabolic contribute to differences heat responses a heat-tolerant soybean genotype DS25-1 heat-susceptible DT97-4290. Both genotypes were grown at optimal temperatures (OT; 30/20 °C) for 15 days. Subsequently, half of the plants exposed (38/28 11 days, rest kept OT.

The objectives of this research were to evaluate a germplasm collection 49 genotypes root traits, determine whether traits related with plant height, shoot dry weight, chlorophyll index, seed size, identify can hardpan. Plants maintained under growth conditions greenhouse. Single plants grown mesocosms,...
Soybean is the primary oilseed crop in United States, with significant industrial value. Understanding molecular mechanisms of heat stress tolerance soybean plants critical for developing stress-resistant cultivars. Current knowledge about role fatty acid desaturases (FADs) modulating membrane fluidity under abiotic prompted this investigation into impact mutations FAD genes on seed germination from heat-stressed plants. In plants, exposure to during anthesis known significantly reduce...
