A novel TMV-induced hot pepper cell wall protein gene (CaTin2) is associated with virus-specific... Incompatible plant-pathogen interactions result in the rapid cell death response known as hypersensitive response (HR) and activation of host defense related genes. To understand the cellular mechanism controlling defense response better, a novel pathogenesis-related (PR) gene and putative cell wall protein gene, CaTin2, was isolated through differential screening of a hot pepper cDNA library and characterized. CaTin2 gene was locally and systemically induced in hot pepper plants upon TMV-P0 inoculation which induces HR. However, CaTin2 gene wasn't regulated by bacterial HR-specific signal pathway. The full-length cDNA for CaTin2, which is 864 nucleotides long, contained the open reading frame of 200 amino acids including cell wall targeting sequences of 26 amino acids. CaTin2 gene has no sequence similarity with other cell wall protein genes except the signal sequence and exists as only one copy in hot pepper genome. CaTin2 gene contains repeated helix-turn-helix motif consisting of 39 amino acids. CaTin2 mRNA accumulation was induced in response to various treatments such as ethylene, SA, MeJA, ABA, methyl viologen, NaCl and wounding at early time points. Subcelluar localization of CaTin2 was confirmed in the cell wall in hot pepper leaves by making CaTin2::smGFP fusion protein. The transgenic plants overexpressing CaTin2 cDNA were resistant to TMV and CMV inoculation. From these results, CaTin2 gene may encode a virus-related new cell wall protein member. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Plant Molecular Biology Springer Journals
