Comparison of induced peroxidase activity in cotton plants resistant and susceptible to Verticillium dahliae. In: Proceedings of the Beltwide Cotton Conferences, January 3-6, 2006, San Antonio, Texas. 2006 CDROM. Interpretive Summary: Peroxidases participate in many reactions and regulate multiple processes in the plant. Among these, chitin-binding peroxidases play a key role. We have investigated peroxidase activity in seven Upland cotton cultivars, and we found that a two-fold increase occurred in the resistant cotton variety AN-BAYAUT 2 after inoculation with Verticillium dahliae. The peroxidase activity in the resistant variety was due to biosynthesis of chitin binding peroxidase isozymes. The susceptible cotton line C-4727 also showed an increase in peroxidase activity, but most of these peroxidase isozymes did not bind to chitin.
