Genome-Wide Identification and Expression Analysis of the NRAMP Family Genes in Tea Plant (Camellia sinensis).

ABSTRACT: The natural resistant-associated macrophage protein (NRAMP) is a kind of integral membrane transporter which could function on a wide range of divalent metal ions in plants. Little is known about the NRAMP family in Camellia sinensis. In this study, 11 NRAMP genes were identified from the tea plant genome. Phylogenetic analysis showed that the 11 CsNRAMP proteins were split into two groups. The proteins of group 1 contained the conserved motif 6 (GQSSTxTG), while most proteins in group 2 (excepting CsNRAMP7 and CsNRAMP10) contained the conserved residues of motif 6 and motif 2 (GQFIMxGFLxLxxKKW). The number of amino acids in coding regions of 11 CsNRAMP genes ranged from 279-1373, and they contained 3-12 transmembrane domains. Quantitative RT-PCR analysis showed that G
