Abstract:Potyviruses are the most important viral pathogens of crops worldwide. Under a contract with Gene Shears Pty Limited, we are using ribozyme genes to protect melon plants against two potyviruses: WMV2 and ZYMV. Different polyribozyme genes were designed, built and introduced into melons plants. Transgenic melon plants containing a resistance gene were obtained and their progeny was challenged by the appropriate virus. Most of the genes tested conferred some degree of resistance to the viruses in glasshouse tria… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
