主 题：Drought stress inducible gene morphological indicator physiological indicator RNA sequencing wheat seedling
摘 要：Drought is the main abiotic stress that restricts wheat *** rapid development of sequencing technology and its widespread application to various fields have revealed the structural characteristics and regulation of related genes through gene expression ***,we studied responses of wheat plants under drought and rewatering conditions,using morphological and physiological ***,a transcriptome analysis was conducted on Jingmai 12,a drought-resistant wheat strain,to explore the mechanism underlying the response of drought-resistant wheat seedlings to drought stress at the transcriptome *** stress caused morphological and physiological changes in both drought-resistant and-sensitive varieties,but to a greater extent in the drought-sensitive *** re-watering,the drought-resistant wheat showed greater ability to recover than the drought-sensitive *** sequencing of Jingmai 12 revealed 97,422 genes,including 80,373 known genes and 17,049 newly predicted *** observed upregulation of genes was mostly involved in hormone and signal transduction,carbon metabolism,amino acid synthesis,small molecule production,transmembrane transport,ROS detoxification and defense,drought response protein,and protective enzyme *** genes were mostly involved in photosynthesis,lipid metabolism,signaling,and auxin *** rehydration,these genes and metabolic pathways returned to *** results suggest that all these changes are adaptations to drought *** morphological adaptation,physiological regulation,and the expression of drought-induced genes,normal growth of drought-resistant varieties under drought stress can be *** results increase our understanding of the transcriptomic changes taking place in drought-resistant wheat seedlings under drought stress,and provide a direction for future investigations.
