Genome-Wide Identification of the Heterotrimeric G-Protein Gene Family and Its Transcriptional Response to Salt Stress in Foxtail Millet

Abstract

Simple Summary G proteins are ubiquitous in plants and play an important role in many biological functions such as plant growth and development, stress response and so on. However, their specific function in foxtail millet (Setaria italica L.) is not clear. In this study, 12 G-protein gene family members were identified in foxtail millet and divided into four categories, and their whole-genome characteristics were analyzed. Transcriptome analysis showed that these members showed different expression patterns under salt-stress treatment at different times. This study increased the understanding of the G-protein gene family and provided valuable genetic resources for foxtail millet breeding.
