Figure 4.

The putative botcinic acid biosynthetic genes (BcBOA) are separated into at least two clusters in the Botrytis cinerea wild‐type (WT) strain B05.10. Black arrows indicate genes that might be involved in botcinic acid biosynthesis in B. cinerea. Dark grey arrows in Sclerotinia sclerotiorum (strain 1980; Sclerotinia sclerotiorum Database, http://www.broadinstitute.org/annotation/genome/sclerotinia_sclerotiorum/MultiHome.html) indicate the genes that are the homologues of the B. cinerea BcBOA genes. Sclerotinia sclerotiorum genes that are probably not related to secondary metabolism and the botcinic acid cluster are indicated by light grey arrows. Grey boxes at the ends of the B. cinerea clusters indicate AT‐rich regions exhibiting AT contents from 70% to 90%.
