Hormone-Virus Interactions in Plants

Abstract

Symptoms of virus infection may be simplistically ascribed to a change in quantity of a particular plant hormone, and frequently virus-induced symptoms can be mimicked by application or removal of a plant hormone. In this review, we look critically at the information available concerning changes in the biosynthesis and metabolism of plant hormones following virus infection. In addition, we briefly review the effects of virus infection on endogenous jasmonates and salicylic acid. We also briefly assess the involvement of the classical plant hormones, jasmonic acid and salicylic acid in the induction of defense-related genes.
