PLoS ONE 11(8):Įditor: Haitao Shi, Hainan University, CHINA (2016) Genome-Wide Identification, Expression Diversication of Dehydrin Gene Family and Characterization of CaDHN3 in Pepper ( Capsicum annuum L.). This study lays the foundation for further studies into the regulation of their expression under various conditions.Ĭitation: Jing H, Li C, Ma F, Ma J-H, Khan A, Wang X, et al. So the CaDHN3 might act as a positive role in resisting abiotic stresses. Furthermore, the CaDHN3 (YSK2)-silenced pepper plants showed obvious lower resistance to abiotic stresses (cold, salt and mannitol) than the control plants (TRV2:00). The gene expression profiles analysis suggested that most of the CaDHN genes were induced by various stresses (low temperature, salt and mannitol) and signaling molecules (ABA, SA and MeJA). Quantitative real-time PCR (qRT-PCR) results showed that the seven DHN genes were expressed in all tissues and might be involved in the growth and development of pepper. In this study, seven CaDHNs in the pepper genome were identified, which could be divided into two classes: YnSKn- and SKn-type, based on their highly conserved domains. Although DHNs have been identified and characterized in many plants, there is little known about Capsicum annuum L., one of the economically important vegetable crops. Dehydrins (DHNs) play a crucial role in enhancing abiotic stress tolerance in plants.
