Differential expression of genes in roots of rice seedlings with contrasting response under low nitrogen

Gene expression study using rice microarray were conducted in root samples of two genotypes, Prasanna and Varadhan at seedling stage under hydroponics with supplemented nitrogen and without nitrogen. The roots displayed morphological differences in terms of root length and overall structure. Higher number of gene families for transporters, transcription factors and some nitrogen uptake transporters were up-regulated in the efficient genotype without nitrogen supplementation. The data overall presents up and downregulated genes, metabolic pathways operated in two genotypes with and without nitrogen supplementation. 14 days seedling in hydroponics, Two replication each, Prasanna and Varadhan IIRR released varieties.
