Integrative analysis of transcriptome and metabolism reveals functional roles of redox homeostasis in low light and salt combined stress in Leymus chinensis.

ABSTRACT: Salt stress is one of the major limiting factors of Leymus chinensis (named sheepgrass) growth, which accelerates inhibitive effects that are particularly concomitant with low light regimes (LL-Salt). However, little is known about physiological and molecular mechanisms under such LL-Salt in sheepgrass. This study aims to uncover the key reprogrammed metabolic pathways induced by LL-Salt through an integrated analysis of transcriptome and metabolism. Results suggested that the growth of sheepgrass seedlings was dramatically inhibited with a ranging of 8 to 20% reduction in F_v/F_m in LL-Salt combined treatments. Catalase activities were increased by 40% in LL but significantly decreased in salt stress, ranging from 15 to 46%. Both transcriptome and metabolism analysis r
