Genome-wide analysis of the AP2/ERF transcription factor superfamily in perennial ryegrass.

ABSTRACT:

Background

Perennial ryegrass (Lolium perenne L.) is a widely cultivated turfgrass and forage species. AP2/ERF transcription factors play indispensable roles in plant growth and development, particularly in responses to biotic and abiotic stresses. However, comprehensive knowledge of this family in perennial ryegrass remains underexplored.

Results

In this study, a total of 172 LpAP2/ERF genes were identified in the perennial ryegrass genome and renamed according to their chromosomal distribution. Phylogenetic and synteny analyses were performed using rice to investigate the evolution of the AP2/ERF genes in perennial ryegrass. These 172 LpAP2/ERF genes were categorized into four distinct subfamilies: the AP2 subfamily (25), the ERF subfamily (84), the DREB subfamily (59), an
