“…To this group belongs a subfamily of heatshock chaperones, 16 represented by HSP30 from Saccharomyces cerevisiae or similar proteins in other fungi (e.g., Cvhsp30/1 and Cvhsp30/2 from Coriolus versicolor). 17 Other presumptive opsins contain the conserved lysine residue, but retinal binding and photoreactivity have not been demonstrated; we shall refer to them as predictable photoactive opsins or PPOs here.…”

Opsins are membrane photoreceptors closely related to the heat-shock proteins of the HSP30 family. Their functions include light-driven ion pumping in archaea and light detection in algae and animals, using the apocarotenoid retinal as a light-absorbing prosthetic group. We describe a gene of Fusarium fujikuroi, carO, coding for a polypeptide resembling opsins and HSP30-like proteins and contiguous to the genes of the carotenoid pathway, carRA and carB. Transcription of carO is induced by light and is deregulated in carotenoid-overproducing mutants. The same regulation pattern is exhibited by carRA and carB; and common conserved DNA elements are found in the three promoters. Heat shock resulted in a modest induction of carO transcription, similar to the one exhibited by carB, confirming a common regulation. Targeted mutagenesis of carO produced no apparent phenotypic modification, including no change in the photoinduction of carotenoid biosynthesis.

Comprehensive analysis of the transcriptome of the P. chrysosporium is a useful approach to improve our understanding of its special and unique enzyme system and fungal evolution in molecular and industrial aspects. In order to unveil the functional diversity of this white-rot fungus in gene level and the expression patterns of its genes, in this study we carried out sequencing and annotation of 4,917 P. chrysosporium expressed sequence tags (ESTs). Through our bioinformatic ESTs analysis, we elucidated that 1,751 genes were derived from the present dataset of 4,917 ESTs, based on clustering and comparative genomic analyses of the ESTs. Of the 1,751 unique ESTs, 1,006 (57.5%) had homologues and orthologues in similarity searches. Our P. chrysosporium ESTs showed many genes for encoding 23 secreted proteins, many proteins for the degradation of cellulose and hemicelluloses, and heat shock proteins for stress resistance, which explain the reason why P. chrysosporium is very important and unique white-rot fungus in dealing with contaminated resources and in degrading lignin and in applying this organism to several industrial aspects.In addition, comparative analysis has shed the fresh light on the mystery about how its unique enzyme system and stress resistance have been evolved differently from its closest relatives.
