We previously cloned the full-length coding sequence of the gene AhMYB44,which showed a stress-induced expression from peanut drought transcriptome sequencing datasets. In order to investigate the function of AhMYB44,a yeast two-hybrid system was deployed for identifying its interacting proteins. The results showed that the bait vector pGBKT7-AhMYB44 was not toxic and showed no self-activation activity. Sixteen coding sequences were identified by screening of cDNA libraries which were constructed from a drought and high-salt stress of peanut. We further conducted an in-silico analysis of their homologous proteins,such as plant transcriptional regulation,growth and development,signal transduction,biotic and abiotic stress responses. Out of that,the candidate gene(No.46)was annotated with the abiotic stress,and encoded for a calcium-dependent phospholipid binding protein(ANNEXIN). Therefore,we speculated that AhMYB44 maybe participate into regulation of peanut stress response process through intracellular calcium signal. This result might provide a reference for further research on the function and mechanism of AhMYB44.
