EFFECTS OF INTERCROPPING OF FLUE-CURED TOBACCO WITH AMERICAN PEPPERMINT ON PROTEOMICS OF FLUE-CURED TOBACCO

Following intercropping the flue-cured tobacco plant with American peppermint the changes in tobacco leaf proteins were investigated. Further, the effect of intercropping tobacco with peppermint on the tobacco leaf proteome was preliminarily explored. The results showed that the expression of anti-biotic stress-related proteins such as chitinase and beta-1,3-glucanase decreased in the intercropped tobacco leaves. While the expressions of anti-abiotic stress-related and glycolytic enzymes such as ribulose-1,5-bisphosphate carboxylase/oxygenase activase, fructose-bisphosphate aldolase, and phosphoglycerate kinase increased. The results demonstrated that the intercropping of flue-cured tobacco with American peppermint was beneficial to the resistance of tobacco against abiotic stress, but not biotic stress.
