Activation of tomato PR and wound-related genes by a mutagenized tomato MAP kinase kinase through divergent pathways

Abstract
A mitogen-activated protein kinase kinase (MAPKK) gene, tMEK2, was isolated from tomato cv. Bonny Best. By mutagenesis, a permanently active variant, tMEK2MUT, was created. Both wild-type tMEK2and...
