Application of substance for adjusting CdCOMT2 expression level in adjusting S/G ratio of lignin

The invention discloses application of a substance for adjusting the expression level of CdCOMT2 in adjusting the S/G ratio of lignin. The first aspect of the application relates to a biological material, including isolated nucleic acid molecules and the like. According to the embodiment of the invention, the expression of the Camellia Gaozhouensis CdCOMT2 gene can regulate and control the synthesis of an S lignin monomer, when the gene is over-expressed in wild type arabidopsis thaliana, the content of G-lignin in tissues such as pericarp and stem of arabidopsis thaliana has no obvious difference, the content of S-lignin is obviously increased, the proportion of S/G lignin is obviously increased, and the content of S-lignin is obviously increased. The method lays a theoretical foundation for molecular research and breeding of camellia oleifera in the aspect of peel lignin regulation and control, and has important application value. 本申请公开了调节CdCOMT2表达水平的物质在调节木质素S/G比中的应用。本申请的第一方面涉及一种生物材料，包括分离的核酸分子等。本申请实施例中发现高州油
