Abstract

CaTin1 was expressed relatively early in the TMV-inoculated leaves of hot pepper which is resistant to TMV-P0 infection. Interestingly, there was another homologous gene (CaTin1-2) located in front of CaTin1 in a head-to-head fashion and they shared a single promoter. The expression profile of the CaTin1-2 was very similar to CaTin1 in all the treatments except the slower induction time compared to CaTin1 upon TMV-P0 inoculation. The promoter analysis of CaTin1 and CaTin1-2 revealed bidirectionality both in cis-elements and activity. The CaTin1-2 promoter had two TATA-boxes, four GCC-boxes, the root responsive element, and a W1-box. The ethylene-inducible promoter activity depended on GCC-boxes and TMV-inducible activity of the CaTin1-2 promoter reached its highest activity when this promoter had a W1-box.
