摘要： COBRA-Like (COBL) genes encode a glycosylphosphatidylinositol (GPI) anchoring protein unique to plants. In current study, 87 COBRA genes were identified in 6 Rosaceae species, including Pyrus bretschneideri (16 genes), Malus domestica (22 genes), Fragaria vesca (13 genes), Prunus mume (11 genes), Rubus occidentalis (13 genes) and Prunus avium (12 genes). We revealed the evolution of the COBRA gene in six Rosaceae species by phylogeny, gene structure, conservative sequence, hydrophobicity analysis, gene replication events and sliding window analysis. In addition, based on the analysis of expression patterns in pear fruit combined with bioinformatics, we identified PbCOBL12 and PbCOBL13 as potential genes regulating secondary cell wall (SCW) formation during pear stone cell development. This study aimed to understand the evolutionary relationship of the COBRA gene in Rosaceae species, clarify the potential function of COBRA in pear fruit development, and provide essential theoretical basis and gene resources for improving pear fruit quality through genetical modification mechanism.
