Activation of a diverse set of genes during the tobacco resistance response to TMV is independent of salicylic acid; induction of a subset is also ethylene independent

Summary Through differential screening of a cDNA library, we cloned six groups of genes that are expressed relatively early in the inoculated leaves of tobacco resisting infection by tobacco mosaic virus (TMV). Induction of all these genes was subsequently detected in the uninoculated leaves; thus,...
