Identification and expression pattern of aluminium-responsive genes in roots of rice genotype with reference to Al-sensitivity.

ABSTRACT: Aluminium (Al) is the third most abundant element in the Earth's crust. Globally, acidic soil occupies 30-40% of ice-free land areas; Al toxicity is a major threat to crops. The first symptom of Al toxicity is the inhibition of root growth followed by poor root hair development, swollen root apices, necrosis of leaves and reduced yield. Although Rice (Oryza sativa) is an Al toxicity tolerant crop, it shows considerable variations among rice genotypes to Al exposure. Therefore, it is pertinent to understand Al toxicity and underlying mechanisms for Al tolerance in Rice. In the present study, 63 rice genotypes screened under Al stress showed significant variations of root growth. Expression stability of endogenous control genes (ECGs) revealed sulphite reductase (SR) as the most stable ECG t
