The long period of seed dormancy is one of the most important reasons leading to the low fertility of dove tree (Davidia involucrata Baill., Davidia hereinafter). During the fruit development process of Davidia, the endocarps will become particularly compact and hard, which was considered as a critical reason for the long seed dormancy of Davidia. However, the biological significance and regulatory mechanism of this process remain unclear. In this study, we identified a CCoAOMT gene, a key member of the lignin biosynthesis pathway, from Davidia...
