Transcriptional characterization and response to defense elicitors of mevalonate pathway genes in cotton (Gossypium arboreum L.).

ABSTRACT: The mevalonate (MVA) pathway is responsible for the biosynthesis of cytosolic terpenes including gossypol and its derivatives, which play an important role in the cotton plant's defense against pathogens and herbivores. In this study, we identified and cloned 17 potentially functional genes encoding enzymes that catalyze the six steps of the MVA pathway in Gossypium arboreum. Expression pattern analysis by qRT-PCR demonstrated that these genes had tissue-specific expression profiles and were most prevalently expressed in roots. Moreover, these genes were up-regulated in response to several elicitors, including methyl jasmonate and salicylic acid, as well as Verticillium dahliae infection and Helicoverpa armigera infestation. This indicates that the MVA pathway genes ar
