Novel Mutations in CYP51B from Penicillium digitatum Involved in Prochloraz Resistance

Green mold caused by Penicillium digitatum is one of themost serious postharvest diseases of citrus fruit, and it isubiquitous in all citrus growing regions in the world. Sterol14α-demethylase (CYP51) is one of the key enzymes of sterolbiosynthesis in the biological kingdom and a prime targetof antifungal drugs. Mutations in CYP51s have been foundto be correlated with resistance to azole fungicides in manyfungal species. To investigate the mechanism of resistance toprochloraz (PRC) in P. digitatum, the PRC sensitivity wasdetermined in vitro in this study to assess the sensitivity of78 P. digitatum isolates collected in Hubei province. Theresults showed that 25 isolates were prochloraz-resistant(PRC-R), including six high-resistant (HR) strains, twelvemedium-resistant (MR) and seven low-resistant (LR) strains. A sequence analysis showed no consistent point mutationsof PdCYP51A in the PRC-R strains, but four substitutionsof CYP51B were found, Q309H in LR strains, Y136H andQ309H in HR strains, and G459S and F506I in MR strains,which corresponded to the four sensitivity levels. Based onthe sequence alignment analysis and homology modelingfollowed by the molecular docking of the PdCYP51B protein,the potential correlation between the mutations and PRC resistance is proposed.
