Multidrug and Toxic Compound Extrusion (MATEs) is one of the characteristic transporter families, which plays a key role in the detoxication of endogenous secondary metabolites and exogenous agents in both animal and plant cells. In this study, we identified a total of 67 MATE genes (CcMATEs) from the pigeonpea genome, on which we performed bioinformatics analysis and we group them by phylogenetic analysis. Finally, eight represented CcMATE genes were selected for further qRT-PCR analysis of tissue specificity and response to metal stress in pigeonpea. The results showed that both CcMATE34 and 45 genes were significantly up-regulated and the CcMATE4 gene was only up-regulated in the roots under the stress of Al, Mn and Zn. We speculated that the function of CcMATE34 and 45 might be related to the transport of alkaloids and harmful substances and the function of CcMATE4 might be related to the delivery of flavonoids.
