Abstract
Recent important discoveries in several laboratories have identified SGT1 as an essential component of R gene-mediated disease resistance in plants. The precise molecular function of SGT1 remains unknown, although sequence analysis and structural predictions reveal that SGT1 has features of co-chaperones that associate with HSP90 in animals. This review will describe the role of SGT1 in R gene-mediated plant defence and discuss how SGT1 may regulate this process.
