Abstract

The first draft of the Chlamydomonas nuclear genome was searched for genes potentially encoding members of the five major chaperone families, Hsp100/Clp, Hsp90, Hsp70, Hsp60, the small heat shock proteins, and the Hsp70 and Cpn60 co-chaperones GrpE and Cpn10/20, respectively. This search yielded 34 potential (co-)chaperone genes, among them those 8 that have been reported earlier inChlamydomonas. These 34 genes encode all the (co-)chaperones that have been expected for the different compartments and organelles from genome searches in Arabidopsis, where 74 genes have been described to encode basically the same set of (co-)chaperones. Genome data from Arabidopsis and Chlamydomonas on the five major chaperone families are compared and discussed, with particular emphasis on chloroplast chaperones.
