Identification and comparative analysis of microRNAs associated with low-N tolerance in rice genotypes.

ABSTRACT:

Background

Nitrogen [N] is a critical limiting nutrient for plants and has to be exogenously supplied to many crops, to achieve high yield with significant economic and environmental costs, specifically for rice. Development of low-input nitrogen sustainable crop is necessary for sustainable agriculture. Identification of regulatory elements associated with low-N tolerance is imperative for formulating innovative approaches for developing low-N tolerant crop plants, using gene manipulation. MicroRNAs (miRNAs) are known to play crucial roles in the modulation of gene expression in plants under various environmental conditions.

Methodology/principal findings

MiRNAs associated with low-N tolerance have not been identified so far. In this study, we investigated microarray-based
