Heat shock proteins (Hsps) represent a group of specific proteins which are synthesized primarily in response to heat shock in almost all biological systems. Members of Hsp100 family have been directly implicated in induction of thermotolerance in microbial and animal cells. Yeast cells harbouring defective hsp104 gene do not show thermotolerance under conditions in which the normal cells do. Several plant species have been shown to synthesize Hsps in the range of 100 kDa. Rice Hsp104 (OsHsp104) is rapidly and predominantly accumulated in heat-shocked cells. Western blotting analysis show that anti rice Hsp104 antibodies (generated against purified Hsp104 protein from cultivated rice Oryza sativa L.) cross-react with the same-sized high temperature inducible protein in 15 different wild rices. It was further found that anti rice Hsp104 antibodies also cross-react with a major high temperature regulated protein ofEscherichia coli. We have previously shown that a 110 kDa stress regulated protein in rice (OsHsp110) is immunologically related to yeast Hsp104 protein. In this paper, we present a comparative account of characteristics of the OsHsp104 and OsHsp110 proteins.
