摘要

Water use efficiency (WUE) and production are closely related to the redox state in plants, through which plants complete conversion of photosynthetic products and their life circle. WUE is an important and integrative physiology trait for stabling and improving crop yield, but the research about WUE were also many controversies, such as high WUE genotypes had more potential to adapt to drought stress. Through measuring gas exchange parameters and stomatal characteristics in different soybean (Glycine max) genotypes at the flowering, two same stomatal limitation genotypes with different WUE were screened for further transcriptomics and quantitative real-time PCR (qRT-PCR). High WUE variety HN44 had better stomatal conductance (C), high photosynthetic rate (Pn) and chlorophyll content (CCI). Pn was extremely significant positive correlation with C and transpiration rate (E), Pn was significant positively correlated with WUE and instant WUE (WUEi). 192 differentially expressed transcription factors (TFs) genes among 3435 genes encoded TFs were predicted by classification and enrichment of Go and KEGG, differentially expressed genes highly focused on photosynthesis functions, and mainly involved in the plant hormone signal transmission and mitogen activated protein kinase (MAPK) signal pathway. Among them, the top 6 high differently expressed relative TFs genes were mined and verified by qRT-PCR, other five genes were up-regulated in HN44 except for GmABI5-Like 1, and GmTIFY5A, GmERF1B, GmbHLH63, GmABI5-Like 1 were involved in same pathway-plant hormone signal transduction.
