Functional conservation and divergence in plant-specific GRF gene family revealed by sequences and expression analysis.

ABSTRACT: Unique to plants, growth regulatory factors (GRFs) play important roles in plant growth and reproduction. This study investigated the evolutionary and functional characteristics associated with plant growth. Using genome-wide analysis of 15 plant species, 173 members of the GRF family were identified and phylogenetically categorized into six groups. All members contained WRC and QLQ conserved domains, and the family's expansion largely depended on segmental duplication. The promoter region of the GRF gene family mainly contained four types of cis-acting elements (light-responsive elements, development-related elements, hormone-responsive elements, and environmental stress-related elements) that are mainly related to gene expression levels.
