Identification, Classification, and Functional Analysis of Family Genes in the Desert Moss .

is a desert moss which shows tolerance to the desert environment and is emerging as a good plant material for identification of stress-related genes. transcription factor family plays important roles in plant responses to biotic and abiotic stresses. genes have been identified and extensively studied in many plants, while they are rarely studied in moss. In the present study, we identified 83 genes based on the comprehensive dehydrationrehydration transcriptomic atlas of . genes can be classified into five families, including 11 AP2s, 43 DREBs, 26 ERFs, 1 RAV, and 2 Soloists. RNA-seq data showed that 83 exhibited elevated transcript abundances during dehydration⁻rehydration process. We used RT-qPCR to validate the expression profiles of 12 representative and confirmed the expression trends using RNA-seq data. Eight out of 12 BaAP2/ERFs demonstrated transactivation activities. Seven BaAP2/ERFs enhanced salt and osmotic stress tolerances of yeast. This is the first study to provide detailed information on the identification, classification, and functional analysis of the in . This study will lay the foundation for the further functional analysis of these genes in plants, as well as provide greater insights into the molecular mechanisms of abiotic stress tolerance of .
