Abstract
Zinc (Zn) and iron (Fe) are essential micronutrients for plant growth and development, their deficiency or excess severely impaired physiological and biochemical reactions of plants. Therefore, a tightly controlled zinc and iron uptake and homeostasis network has been evolved in plants. The Zinc-regulated transporters, Iron-regulated transporter-like Proteins (ZIP) are capable of uptaking and transporting divalent metal ion and are suggested to play critical roles in balancing metal uptake and homeostasis, though a detailed analysis of ZIP gene family in Oryza sativa L. ssp indica is still lacking. Therefore, in order to identify and characterize ZIP gene family in Oryza sativa L. ssp indica we developed a BLAST based approach. By using this approach we were able to identify 21 putative ZIP transporter genes in indica genome. Phylogenetic analysis indicated that they form well-supported nine classes, which were further divided into subclasses. The distribution of OsIZIP genes was found to be random across chromosomes
