In this study, 46 MATE proteins were identified in the rice genome through homology searches and domain prediction. The rice MATE family was classified into four subfamilies based on phylogenetic analysis. Tandem repeats and fragment replication contributed to the expansion of the MATE gene family in rice. Most MATE genes were found to be constitutively expressed in different tissues, with differential expression patterns observed in response to salt and drought stress. This study provides comprehensive information on the MATE gene family in rice and aids in understanding the functional divergence of MATE genes.
Multidrug and toxic compound extrusion (MATE) proteins are involved in many physiological functions of plant growth and development. Although an increasing number of MATE proteins have been identified, the understanding of MATE proteins is still very limited in rice. In this study, 46 MATE proteins were identified from the rice (Oryza sativa) genome by homology searches and domain prediction. The rice MATE family was divided into four subfamilies based on the phylogenetic tree. Tandem repeats and fragment replication contribute to the expansion of the rice MATE gene family. Gene structure and cis-regulatory elements reveal the potential functions of MATE genes. Analysis of gene expression showed that most of MATE genes were constitutively expressed and the expression patterns of genes in different tissues were analyzed using RNA-seq. Furthermore, qRT-PCR-based analysis showed differential expression patterns in response to salt and drought stress. The analysis results of this study provide comprehensive information on the MATE gene family in rice and will aid in understanding the functional divergence of MATE genes.
