The CaChiVI2 gene of Capsicum annuumL. confers resistance against heat stressand infection ofPhytophthora capsici.

Extreme environmental condition is a serious issue affecting crop growth and development, resulting in substantial reduction in crop yield and quality. However, chitin-binding proteins (CBP) family member CaChiVI2 plays a crucial role in eliminatingthe impact of adverse environmental conditions. For the first time it was discovered that CaChiVI2 (Capana08g001237) gene of pepper (Capsicum annuum L.) had arole in resistance to heat stress and physiological processes. The full-length open-reading frame (ORF) of CaChiVI2 (606-bp, encoding 201-amino acids), was cloned into TRV2:CaChiVI2 vector for silencing.
