Understanding the differential nitrogen sensing mechanism in rice genotypes through expression analysis of high and low affinity ammonium transporter genes.

Molecular biology reports - 1 Mar 2012

Gaur Vikram Singh, Singh U S, Gupta Atul K, Kumar Anil

Abstract excerpt

Two rice genotypes, Kalanamak 3119 (KN3119) and Pusa Basmati 1(PB1) differing in their optimum nitrogen requirements (30 and 120 kg/ha, respectively) were undertaken to study the expression of both high and low affinity ammonium transporter genes responsible for ammonium uptake. Exposing the roots of the seedlings of both the genotypes to increasing (NH(4))(2)SO(4) concentrations revealed that all the three...
