Transcriptomics combined with physiological analysis and metabolomics revealed the response of potato tuber formation to nitrogen.

ABSTRACT: The absorption of the essential element nitrogen by plants affects various aspects of plant physiological activity, including gene expression, metabolite content and growth. However, the molecular mechanism underlying the potato tuberization response to nitrogen remains unclear. Potato plants were subjected to pot experiments under nitrogen deficiency, normal nitrogen levels and nitrogen sufficiency. A comprehensive analysis of the physiological responses, transcriptomic profiles, and metabolic pathways of potato stolons subjected to nitrogen stress was conducted. Transcriptomic analysis revealed 2756 differentially expressed genes (DEGs) associated with nitrogen stress. Metabolomic analysis identified a total of 600 differentially accumulated metabolites (DAMs). Further correlation analys
