Robert Henry Symons 1934–2006

Abstract

Bob Symons died in Adelaide on 4 October 2006 after a long illness. He was distinguished through his contributions to our knowledge of the structure, function and replication of plant viruses, viroids and virusoids. His research culminated in the discovery of the hammerhead folding of the RNA chain and its role as a ribozyme in self-cleavage of the RNA in some of these plant pathogens. He was a leader in his field and was responsible for commercial applications of his research and the establishment in Adelaide of the first Australian company to produce and market molecular biologicals for research.
