Gene Os05g0128400,namely OsMTP1 and OZT1, is a rice metal tolerance protein and a vacuolar zinc transporter.[1][2]
Contents
Annotated Information
Function
Rice (Oryza sativa L. ‘Nipponbare’) cDNA subtractive suppression hybridization (SSH) libraries constructed using cadmium (Cd)-treated seedling roots were screened to isolate Cd-responsive genes. A cDNA clone, encoding the rice homolog of Metal Tolerance Protein (OsMTP1), was induced by Cd treatment. Plant MTPs belong to cation diffusion facilitator (CDF) protein family, which are widespread in bacteria, fungi, plants, and animals.OsMTP1 fused to green fluorescent protein was localized in onion epidermal cell plasma membranes, consistent with an OsMTP1 function in heavy metal transporting. OsMTP1 dsRNAi mediated by transgenic assay in rice seedlings resulted in heavy metal sensitivity and changed the heavy metal accumulation in different organs of mature rice under low-concentration heavy metal stress. [1] The CDF family is a ubiquitous family that has been identified in prokaryotes, eukaryotes, and archaea. Members of this family are important heavy metal transporters that transport metal ions out of the cytoplasm. In this research, a full length cDNA named Oryza sativa Zn Transporter 1 (OZT1) that closely related to rat ZnT-2 (Zn Transporter 2) gene was isolated from rice. The OZT1 encoding a CDF family protein shares 28.2 % ~ 84.3 % of identities and 49.3 % ~ 90.9 % of similarities with other zinc transporters such as RnZnT-2, HsZnT-8, RnZnT-8 and AtMTP1.[2]
Expression
OsMTP1 heterologous expression in yeast mutants showed that OsMTP1 was able to complement the mutant strains’ hypersensitivity to Ni, Cd, and Zn, but not other metals including Co and Mn. OsMTP1 expression increased tolerance to Zn, Cd, and Ni in wild-type yeast BY4741 during the exponential growth phase. [1] OZT1 was constitutively expressed in various rice tissues. The OZT1 expression was significantly induced both in the seedlings of japonica rice Nipponbare and indica rice IR26 in response to Zn2+ and Cd2+ treatments. Besides, OZT1 expression was also increased when exposed to other excess metals, such as Cu2+, Fe2+ and Mg2+. Subcellular localization analysis indicated that OZT1 localized to vacuole. Heterologous expression of OZT1 in yeast increased tolerance to Zn2+ and Cd2+ stress but not the Mg2+ stress.[2]
Evolution
OsMTP1 is a bivalent cation transporter localized in the cell membrane, which is necessary for efficient translocation of Zn, Cd and other heavy metals, and maintain ion homeostasis in plant.[1] OZT1 is a CDF family vacuolar zinc transporter conferring tolerance to Zn2+ and Cd2+ stress, which is important to transporting and homeostasis of Zn, Cd or other heavy metals in plants.[2]
