In cotton, sesquiterpene phytoalexins are elicited in response to bacterial or fungal infection. A Gossypium arboreum cell suspension culture which produces the sesquiterpene phytoalexin gossypol showed a time-dependent 10-fold increase in a 1.9-kb mRNA in response to a challenge by a preparation
Verticillium wilt is a vascular disease of cotton. The causal fungus, Verticillium dahliae, secretes elicitors in culture. We have generated approximately 1,000 5'-terminal expressed sequence tags (ESTs) from a cultured mycelium of V. dahliae. A number of ESTs were found to encode proteins harboring
The cotton (+)-delta-cadinene synthase (CAD1), a sesquiterpene cyclase, catalyzes a branch-point step leading to biosynthesis of sesquiterpene phytoalexins, including gossypol. CAD1-A is a member of CAD1 gene family, and its promoter contains a W-box palindrome with two reversely oriented TGAC
