Integration of the metabolome and transcriptome reveals the resistance mechanism to low nitrogen in wild soybean seedling roots

Wild soybean is the progenitor of cultivated soybean that has excellent low-nitrogen (N) tolerance. This study revealed the mechanism of resistance to low N in wild soybean seedling roots by analyzing the differences in the physiology, metabolome and transcriptome. Under low-N stress, low-N-tolerant wild soybean seedling roots underwent less growth inhibition, producing longer roots that had a higher carbon (C)/N ratio and C, NO3−, Fe2+, Zn2+,...
