Lignin is an integral part of secondary cell walls in plants and plays important roles in maintaining the strength of stems,enhancing transport ability of stems,and providing resistance to multiple stresses.Lignin biosynthesis has become one of the hotspots in molecular forest biol-ogy research.The AP1 transcription factor plays important roles in plant flower development.However,in this study,suppression of BpAP1 altered the transcription profiles of white birch and RNA-seq was used to find that suppression of BpAP1 changed the expression of lignin pathway-related genes;C4H/CYP73A,POD were down-regulated and HCT,CCoAOMT,REF1 and CAD were up-regulated.Cell walls of the suppressed transgenic birch were significantly thinner than the wild type of birch,and BpAP1-repressed birch con-tained less lignin.In addition to regulation of floral develop-ment,BpAP1 might play a role in regulating the expression of genes in lignin biosynthesis of birch.This study could provide a new insight into the function of AP1 genes in woody species.
