Genome-Wide Identification and Expression Analysis of the Copper Transporter (/) Gene Family in , a Typical Mangrove Plant.

The copper transporter (/) gene family plays a critical part in maintaining the balance of the metal, and many diverse species depend on to move copper (Cu) across the cell membrane. In , , , , , , and a genome-wide study of the COPT protein family was performed. To understand the major roles of the gene family in (), a genome-wide study identified four genes in the genome for the first time. The domain and 3D structural variation, phylogenetic tree, chromosomal distributions, gene structure, motif analysis, subcellular localization, cis-regulatory elements, synteny and duplication analysis, and expression profiles in leaves and Cu were all investigated in this research. Structural and sequence investigations show that most have three transmembrane domains (TMDs). According to phylogenetic research, these might be divided into two subgroups, just like . gene segmental duplications and positive selection pressure were discovered by universal analysis. According to gene structure and motif analysis, most genes showed consistent exon-intron and motif organization within the same group. In addition, we found five hormones and four stress- and seven light-responsive cis-elements in the promoters. The expression studies revealed that all four genes changed their expression levels in response to copper (CuCl) treatments. In summary, our study offers a thorough overview of the gene family's expression pattern and functional diversity, making it easier to characterize each gene's function in the future.
