Identification and Characterization of the CCoAOMT Gene Family in Apple, Chinese White Pear, and Peach

Lignin is one of the main components plant cell walls, which provides mechanical support for plants and also contributes to resisting against pathogenic fungi. In fruit industry, lignin content can affect quality fruit. The biosynthesis involves a variety enzymes, caffeoyl-CoA 3-O-methyltransferase ( CCoAOMT ) class methyltransferases that plays an essential role in biosynthesis. Studies have been conducted on gene family several species, including arabidopsis Arabidopsis thaliana ), black poplar Populus nigra cotton Gossypium hirsutum ). Still, there relatively little research this Rosaceae. study, we used bioinformatics identify characterize apple Malus domestica chinese white pear Pyrus bretschneideri peach Prunus persica total, 35 genes were identified three Rosaceae species: 8 from pear, 12 apple, 15 peach. By using structure analysis collinearity analysis, found conserved motifs pairs with collinearity. phylogenetic tree, was mainly divided into two groups. had different expression patterns during growth development stage fruit, finding consistent pattern accumulation. This study will be beneficial further genes.
