Abstract
Hot pepper (Capsicum annuum L. cv. Bugang) plants exhibit a hypersensitive response (HR) upon infection by Tobacco mosaic virus (TMV) pathotype P0. Previously, to elucidate molecular mechanism that underlies this resistance, hot pepper cv. Bugang leaves were inoculated with TMV-P0 and genes specifically up-regulated during the HR were isolated by microarray analysis. One of the clones, Capsicum annuum cytosolic pyruvate kinase 1 (CaPK c 1) gene was increased specifically in the incompatible interaction with TMV-P0. The expression of CaPK c 1 gene was also triggered not only by various hormones such as salicylic acid (SA), ethylene, and methyl jasmonate (MeJA), but also NaCl and wounding. These results suggest that CaPK c 1 responds to several defense-related abiotic stresses in addition to TMV infection.Keywords
