Transcriptome and gene co-expression network analysis revealed a putative regulatory mechanism of low nitrogen response in rice seedlings.

ABSTRACT: In rice, nitrate (NO₃ ^-) and ammonium (NH₄ ⁺) are the main sources of inorganic nitrogen (N) for growth, which also serve as signaling molecules. Depending on the N status, plants modulate their physiological traits such as root system architecture (RSA) and transcriptome makeup, including N uptake and assimilation genes, to adapt to the amount of N available in the growth medium. In this study, time-course hydroponic experiment under low N (0.4 mM NH₄ ⁺) and sufficient N (1.6 mM NH₄ ⁺) was performed using low N tolerant introgression lines, KRIL8 and KRIL37, which carry a small region of the wild rice Oryza rufipogon genome in the Oryza sativa L. cv Koshihikari background.
