PCMT1 and infection: In the present study, the regulated genes, including cytochrome P450 (IFM89_017692), coclaurine N-methyltransferase (IFM89_033035), S-norcoclaurine synthase (IFM89_032242, IFM89_032109, and IFM89_012604), cytoplasmic tRNA 2-thiolation protein (IFM89_004268), and Protein-l-isoaspartate (d-aspartate) O-methyltransferase (IFM89_005471) were identification significantly downregulated by root rot pathogen infection in C. chinensis.
