ABSTRACT
A small-subunit peroxisomal catalase gene, cgcat1, was cloned from Colletotrichum gloeosporioides f. sp. malvae, a hemibiotrophic pathogen of round-leaved mallow (Malva pusilla). When compared to the expression of an actin gene of the fungus, a much lower level of expression of cgcat1 was detected in the biotrophic phase than in the subsequent necrotrophic phase of infection. In culture, cgcat1was expressed at higher levels when exposed to hydrogen peroxide. Changes in cgcat1 expression during infection may have related to an attempt to prevent damage from hydrogen peroxide from degenerating host cells, and/or resulted from changes in fungal nutrition and development during invasion of the host.
