Transition metals are essential minerals required for normal growth and development of plants which are taken in correct proportions from the soil and distributed throughout the plant. The concentrations of transition metals in roots, shoots and grains were analyzed in Oryza sativa indica cultivars viz., Sona Masuri (BPT 5204), Swarna (MTU 7029) and Vijetha (MTU1001). In roots the concentration of iron was highest in Sona masuri variety, followed by manganese and zinc. In shoots and grains, iron was highest followed by zinc suggesting specific transport mechanisms in all the parts. A total of 55 genes for transition metal ion transport were identified using insilico tools of which 18 involved in zinc/iron transport, 13 for copper, 7 for manganese, 3 for cobalt, 4 for cadmium and 10 transport metal ions belonging to Nramp family. Research carried out on these metal transporters mainly provides insights into the field of rice metal biology.
