title: Pathogen-inducible CaUGT1 is involved in resistance response against TMV infection by controlling salicylic acid accumulation.
abstract: Capsicum annuum L. Bugang exhibits a hypersensitive response against Tobacco mosaic virus (TMV) P(0) infection. The C. annuumUDP-glucosyltransferase 1 (CaUGT1) gene was upregulated during resistance response to TMV and by salicylic acid, ethephon, methyl viologen, and sodium nitroprusside treatment. When the gene was downregulated by virus-induced gene silencing, a delayed HR was observed. In addition, free and total SA concentrations in the CaUGT1-downregulated hot pepper were decreased by 52% and 48% compared to that of the control plants, respectively. This suggested that the CaUGT1 gene was involved in resistance response against TMV infection by controlling the accumulation of SA.
