摘要
Abstract
Jasmonic acid as a plant hormone, which is important on pathogenic microorganisms and insect defense response in high plant.COI1 ( COR-insensitive 1) as the receptor of JA signal, plays a key role in the signal transduction.Comparative genomic analysis was performed to investigate the original and evolutionary relationship among COI paralogs in plants.The main results are as follows: ( 1 ) 55 COI homologs were identified from 7 representative terrestrial species.Moreover, there were no COI homologs in aquatic algae.Phylogenetic analysis revealed 4 well-conserved subfamilies in plants.Lineage-specific expansion and functional differentiation exists among COI gene family.( 3) Exon-intron structure analysis revealed that the gene structures of COI gene family is diversity,which has a variable number and length of introns.(4)Gene data suggest that COI gene family is involved in plant growth and development, and play different roles in different tissues and stress response.We provide valuable information for investigating the COI protein family in plants.关键词
