Genome-wide identification and expression analysis of soybean bHLH transcription factor and its molecular mechanism on grain protein synthesis.

ABSTRACT:

Introduction

Soybean seeds have a protein content of about 40% and are widely used due to their unique nutritional value. Research has found that drought and nitrogen fertilizer environments are conducive to the formation and accumulation of grain protein. Nitrogen is an essential element for soybean growth and development, and is converted into grain protein through a series of pathways such as the soybean root nodule system. The earliest report on the regulation of nodulation by bHLH transcription factors in leguminous plants was in 2011, but the network regulatory mechanism of their involvement in soybean protein synthesis is still unclear.

Methods

This study we use BLASTP and HMMER to identified 296 soybean GmbHLH genes through whole-genome identification and systematic
