ABSTRACT=SnRKs play vital roles in plant growth and stress responses. However, little is known about the SnRK functions in wheat. In this study, 149 TaSnRKs were identified and were divided into three subfamilies. A combination of public transcriptome data and qRT-PCR analysis revealed the distinct expression patterns of TaSnRKs under various abiotic and biotic stresses. TaSnRK2.4-B, a member of SnRK2s, has different expression patterns under PEG, NaCl treatment, and the high concentrations of ABA application. Yeast-two-hybrid assay indicated that TaSnRK2.4-B could interact with TaSCS, and play roles in ABA-dependent pathway. Moreover, TaSnRK2.4-B might be a negative regulator in wheat against pathogen infection. The present results provide useful information for understanding the functions of TaSnRKs family and provide clues for the future genetic improvement in wheat stress resistance.
