چکیده	Stevia (Stevia rebaudiana Bertoni) is a natural sweetener plant that accumulates highly sweet steviol glycosides (SGs) especially in leaves. Stevia is native to humid areas and does not have a high tolerance to drought which is the most serious abiotic stress restricting its production worldwide. C2H2 zinc finger proteins (C2H2-ZFPs) are a group of well-known transcription factors that involves in various developmental, physiological and biochemical activities as well as in response to abiotic stresses. Here we analyzed C2H2-ZFP gene family in stevia and identified a total of 185 putative SrC2H2-ZF proteins from the genome sequence of S. rebaudiana. We further characterized the identified C2H2-ZF domains and their organization, additional domains and motifs and analyzed their physicochemical properties, localization and gene expression patterns. The cis-element analysis suggested multiple roles of SrC2H2-ZFPs in response to light, phytohormone, and abiotic stresses. In silico analysis revealed that the stevia C2H2-ZFP genes are interactively expressed in different tissues and developmental stages and some C2H2-ZFP genes are involved in response to drought stress. This study provides a background for future exploration of the functional, and regulatory aspects of the C2H2-ZFP gene family in S. rebaudiana.
