Abstract: The Arabidopsis GELP genes were used as queries and 86 GELP gene members, which can be divided into 8 subgroups, were obtained from the tea plant. The amino acids of the encoding proteins were 171~753, the theoretical isoelectric points were 4.35~9.48, and the molecular weights were 18.594 19~84.550 54 kDa. Gene structure analysis showed that most members have 3~13 exons. Several cis-elements were identified in the promoter regions of the CsGELP genes that are important in regulating growth, development, light responses and the response to several stresses. Most members contain the MYB and MYC elements, which are in volved in responses to salt and cold-stresses. Transcriptome analysis showed that the expressions of CsGELP79, CsGELP64, CsGELP86, and CsGELP4 were enhanced in cold, PEG, NaCl, and MeJA treaments, respectively, indicating that CsGELP79 strongly responded to Cold stress, CsGELP64 strongly responded to drought stress, CsGELP86 strongly responded to high salt stress, and CsGELP4 strongly responded to disease and insect resistance. In addition, CsGELP1, CsGELP12, CsGELP14, CsGELP15, CsGELP18, CsGELP32, CsGELP55 were all down-regulated under various treatments, suggesting that these genes play a negative regulatory role in stress responses.
