Genome-wide identification and analysis of the FLA gene family in maize (Zea mays L.) and its expression in response to abiotic stresses.

ABSTRACT:

Background

Fasciclin-like arabinogalactan proteins (FLAs) are a class of plant-specific proteins that contribute to various aspects of plant growth, development, and adaptation. However, these proteins have not yet been identified or characterized in maize. This study conducted bioinformatics and expression analyses of the ZmFLA gene family.

Results

Based on the homologous comparison methods, 27 ZmFLAs were identified in maize. They were unevenly distributed across ten maize chromosomes, forming 14 pairs of fragment replication with no tandem duplication, revealing that segmental duplication might be the main driving force of the family expansion. Ka/ks analysis of duplicated genes indicating ZmFLAs may undergoing both positively selected and purification selection in evolut
