A transcriptional regulatory module controls lipid accumulation in soybean

Soybean (Glycine max) is one of the most important oilseed crops. However, regulatory mechanism that governs process oil accumulation in soybean remains poorly understood. In this study, GmZF392, a tandem CCCH zinc finger (TZF) protein which was identified our previous RNA-seq analysis seed-preferred transcription factors, found to function as positive regulator lipid production. GmZF392 promotes seed both transgenic Arabidopsis and stable plants by binding bipartite cis-element, containing TG- TA-rich sequences, promoter regions, activating expression genes biosynthesis pathway. physically interacts with GmZF351, previously transcriptional biosynthesis, synergistically promote downstream gene expression. Both GmZF351 are further upregulated GmNFYA, another factor involved directly (in former case) indirectly latter case). Promoter sequence diversity showed may have been selected at origin Glycine genus mildly during domestication from wild soybeans cultivated soybeans.
