Transcriptome Analysis of Nitrogen-Deficiency-Responsive Genes in Two Potato Cultivars

The potato is the third largest food crop, and nitrogen fertilizer important for increasing yields; however, shallow root system of potatoes causes utilization rate to be low, which results in waste environmental pollution, meaning that high efficiency breeding highly significant potatoes. In potatoes, genes with a nitrogen-deficient response should first identified, RNA-seq an efficient method identifying nitrogen-deficiency-response genes. this study, two cultivars, Dongnong 322 (DN322) 314 (DN314), were utilized, application rates (N0 N1) set both cultivars. Through determination physiological indicators, we identified DN314 more sensitive fertilizer, while DN322 relatively insensitive fertilizer. Samples taken at seedling tuber formation stage. At stage, had 573 150 differentially expressed (DEGs), they 59 1905 DEGs, respectively. A total three related low-nitrogen obtained via combined analysis (DEGs) weighted correlation network (WGCNA), stage one gene providing theoretical guidance
