                    The genetic control underlying natural variation in lignin content and composition in trees is not fully understood. We performed a systems genetic analysis to uncover the genetic regulation of lignin biosynthesis in a natural ‘SwAsp’ population of aspen (
                    Populus tremula
                    ) trees.
                  
                
                
                  We analyzed gene expression by RNA sequencing (RNA‐seq) in differentiating xylem tissues, and lignin content and composition using Pyrolysis‐GC‐MS in mature wood of 268 trees from 99 genotypes.
                
                
                  
                    Abundant variation was observed for lignin content and composition, and genome‐wide association study identified proteins in the pentose phosphate pathway and arabinogalactan protein glycosylation among the top‐ranked genes that are associated with these traits. Variation in gene expression and the associated genetic polymorphism was revealed through the identification of 312 705 local and 292 003 distant expression quantitative trait loci (eQTL). A co‐expression network analysis suggested modularization of lignin biosynthesis and novel functions for the lignin‐biosynthetic CINNAMYL ALCOHOL DEHYDROGENASE 2 and CAFFEOYL‐CoA O‐METHYLTRANSFERASE 3.
                    PHENYLALANINE AMMONIA LYASE 3

                    HOMEOBOX PROTEIN 5
                    (HB5), and the role of HB5 in stimulating lignification was demonstrated in transgenic trees.
