Evaluation of growth, yield, relative performance and heat susceptibility of eight wheat (Triticum aestivum L.) genotypes grown under heat stress
Eight spring wheat cultivars were evaluated under three heat stress conditions (early, late and very late) in order to identify suitable cultivars to develop heattolerant genotypes resistant to future global warming. Results from the study indicate that stress did not negatively affect flag leaf area in ‘Prodip’ and ‘Sufi’, flag leaf dry matter partitioning in ‘Prodip’, ‘BARI Gom-26’ and ‘S...
متن کاملHeat-responsive microRNAs regulate the transcription factors and heat shock proteins in modulating thermo-stability of starch biosynthesis enzymes in wheat (Triticum aestivum L.) under the heat stress
Heat-responsive miRNAs regulate the expression of the transcription factors (HSFs) and majority of the heat stress-associated genes (HSPs). Here we report identification of few heats responsive miRNAs in wheat (Triticum aestivum L.)through de novo sequencing on Illumina Hiseq 2000. Validation of identified miRNAs in endospermic tissues of thermotolerant (HD2985) and thermosusceptible (NIAW-34-3...
متن کاملCharacterization of differentially expressed stress-associated proteins in starch granule development under heat stress in wheat (Triticum aestivum L.).
Abiotic stress causes abrupt increase in the expression of stress-associated proteins, which provide tolerance by modulating the defense mechanism of plants. Small heat shock proteins (sHSPs) and anti-oxidant enzymes are important for environmental stress tolerance of the plants. In this study, two full-length cDNAs encoding small heat shock protein (sHSP) and superoxide dismutase (SOD), design...
متن کاملPhysiological assessment of drought tolerance in wheat (Triticum aestivum L.) varieties under moisture stress conditions
Drought is one of the major limiting factors in wheat production in Pakistan. Five commercial wheat varieties; Chakwal-97, Inqilab-91, Margalla-99, NR-234 and Wafaq2001 were grown in pots in glasshouse. Plants were subjected to three consecutive drought cycles at tillering, pre-anthesis and milky growth stages by withholding water till leaf rolling started. Measurements of physiological respons...
متن کاملIdentification of Heat Stress Traits in Wheat (triticum Aestivum L.) in the Way of Tagging Major Gene(s) for Heat Stress Tolerant
A field experiment was conducted with four wheat varieties Raj4134, HD2733, NW 1014 and K9006 for characterization of heat stress tolerance traits under heat stress condition. Heat stress was induced by delayed sowing of 35 days from normal date of sowing so that grain filling stage of wheat could experience severe heat stress. Data related to plant height, chlorophyll content, starch content a...
