The pectinolytic enzyme pectin methylesterase (PME) hydrolyses pectin in methanol and polygalacturonic acid. In the expressed sequence tag library of Botrytis cinerea T4, we identified a 1,041 bp Bcpme1 cDNA potentially encoding a 346-amino acid protein of 37 kDa showing 46.8% identity with Aspergillus sp. PMEs. Bcpme1 is a single copy gene and is similarly expressed in glucose and pectin containing media. To evaluate the role of Bcpme1 in Botrytis cinerea virulence, a mutant in Bcpme1 was… CONTINUE READING
