Abstract Membrane transporters, such as aluminium-activated malate transporter (ALMTs) and multidrug and toxic compound extrusion (MATE), are encoded by key genes that confer plants resistance to aluminiumtoxicity. In this study, based on the full-length transcriptome data of Cunninghamia lanceolata, a total of 8 ALMT genes and 44 MATE genes were identified, which were classified into 3 and 4 subfamilies, respectively. Genes within the same subfamily shared similar conserved motifs and domains. Cis-acting element analysis revealed that the promoters of ALMT and MATE genes in C. lanceolata contained abundant hormone-responsive and stress-responsive elements. Further expression analysis indicated that some ALMT and MATE genes of C. lanceolata exhibited certain expression specificity in different tissues and organs. The expression levels of ClALMT3, ClALMT5, ClMATE15 and ClMATE34 were significantly induced by aluminium stress, suggesting their potential involvement in aluminiumtoxicity resistance of C. lanceolata. These results provide theoretical basis for further studies on the functions of ALMT and MATE genes in the aluminiumstress resistance process of C. lanceolata.
