In this study, the CsCIGR gene was cloned from Camellia sinensis cultivar ‘Longjing 43’ by RTPCR method based on tea genome database. Sequence analysis showed that the open reading frame length of CsCIGR gene was 1 677 bp, encoding 588 amino acids. Evolutionary analysis indicated that CsCIGR belongs to the PAT1 subfamily of the GRAS family. Multiple sequence alignments indicate that the CsCIGR protein of tea plants has a high degree of similarity to the amino acid sequences of GRAS proteins from other plants. The physicochemical properties of amino acids showed that CsCIGR transcription factor was a hydrophilic proteins. Subcellular localization prediction indicates that CsCIGR may be located in the nucleus. Promoter prediction analysis showed that the promoter region of CsCIGR contained stress response element (STRE), drought response element (MYC), anaerobic inducer (ARE) and other cisacting elements related to stress response. The results of qRTPCR showed that the CsCIGR gene responded to high temperature (38 ℃), low temperature (4 ℃), drought (200 g·L^-1 PEG) and high salinity(200 mmol·L^-1 NaCl). The expression levels of CsCIGR were significantly induced by high salinity, low temperature, and high temperature stresses. It is speculated that CsCIGR gene plays an important role in the response of C. sinensis to stresses. The results of this study provide important theoretical basis for screening genes of C. sinensis resistance breeding.
