Abstract
Camelina (Camelina sativa L.) is an annual, self-pollinating, allohexaploid and with diploidization inheritance belonging to the Brassicaceae family, showing significant similarities to the model plant, Arabidopsis thaliana.
As an important oil crop, Camelina exhibits robust tolerance to various environmental stresses. WRKY transcription factors serve as crucial gene regulators involved in regulating biological processes and stress responses in plants. Characterized by the presence of a conserved functional domain comprising 60 amino acids (WRKYGQK motif), WRKY gene family members play key roles in numerous developmental and physiological processes, including embryogenesis, seed coat development, trichome development, anthocyanin biosynthesis, and as well as hormone signaling. Moreover, many WRKY genes are crucial players in mediating camelina responses to different stresses such as H2O2, UV radiation, drought, cold, heat, and salinity. Despite their importance, our knowledge regarding the WRKY gene family roles in Camelina remains limited. In this study, we conducted a comprehensive genome-wide in silico analysis to identify and characterize the WRKY genes in Camelina genome, aiming to pinpoint candidate WRKY genes associated with drought stress responses.
