Abstract: Abstract: Plant lignin is an essential factor of affecting pulp quality. Pinaceae plants is an important pulp material which means the overall understanding of patterns and controlling factors of lignin synthesis related genes is key for improving the modeling of lignin synthesis. According the current research results, the lignin structure, the lignin synthesis pathway and the related enzymes gene of lignin synthesis in Pinaceae are summarized. Some related genes of lignin synthesis in Pinus taeda, P. massoniana, P. radiata, Picea abie and so on have been researched. The lignin syntheses genes of Pinaceae researches were mainly concentrated in common genes, such as phenylalanine ammonolyase(PAL), 4-coumarate: coenzyme A ligase(4CL), cinnamic 4-hydroxygenase(C4H), coumarate 3-hydroxylase(C3H), caffeoyl coenzyme A-O-methyltransferase(CCoAOMT), cinnamoyl CoA reductase(CCR)and cinnamyl alcohol dehydrogenase(CAD), however, some genes that lack current research, including shikimate hydroxycinnamoyl transferase(HCT), ferulate 5-hydroxylase(F5H), O-methyltransferase(OMT), and caffeic acid O-methyltransferase(COMT). Moreover, some genes were not involved in the study. Lignin synthesis is the essential process of exploring pulp quality of Pinaceae. A better understanding of existing problems of the research on lignin synthesis could contribute to further research on the mechanism of lignin synthesis and help to select high quality pulp genotype in Pinaceae plants.
