Differential metal selectivity and gene expression of two zinc transporters from rice.

Plant physiology - 1 Sept 2003

Ramesh Sunita A, Shin Ryoung, Eide David J, Schachtman Daniel P

Abstract excerpt

Zinc is an essential mineral for a wide variety of physiological and biochemical processes. To understand zinc transport in cereals, we identified putative zinc transporters in gene databases. Three full-length cDNAs were identified and characterized from rice (Oryza sativa). Two of the cDNAs partially complemented a yeast (Saccharomyces cerevisiae) mutant deficient in zinc uptake at low concentrations. The two...
