主　　题：BpAP1 Lignin biosynthesis RNA-seq Wood fiber cell walls 

摘      要：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 *** biosynthesis has become one of the hotspots in molecular forest biology *** AP1 transcription factor plays important roles in plant fower ***,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;C4 H/CYP73A,POD were down-regulated and HCT,CCoAOMT,REF1 and CAD were *** walls of the suppressed transgenic birch were significantly thinner than the wild type of birch,and Bp AP1-repressed birch contained less *** addition to regulation of foral development,BpAP1 might play a role in regulating the expression of genes in lignin biosynthesis of *** study could provide a new insight into the function of AP1 genes in woody species.
