Abstract:

The members of laccase(LAC)family in peach[Prunus persica L.(Batsch)] were identified by bioinformatics technology,and their evolutionary relationship,gene structure,cis-elements in promoter region and expression pattern were analyzed. The results showed that a total of 48 laccase genes were identified in peach genome. Through the analysis of expression pattern in peach cotyledon callus,it was found that a key member with high expression,PpLAC21,decreased the content of lignin in peach callus silenced by this gene. It is speculated that this gene may be involved in lignin synthesis in peach callus.

Key words: peach, laccase, callus, virus-induced gene silencing
