Consistent with this, a large number of genes (422 genes) belonging to the glycoside hydrolase (GH) family, including GH3 (29), GH16 (27) and GH18 (21) in the top three, were enriched in the genome of C. camelliae, and these gene clusters are concluded to be important pathogenetic factors of C. camelliae, which was identified to be responsible for the fungal infection and pathogenicity. The gene discussed is H3-4; the disease is fungal infectious disease.
