Network Analysis of Metabolome and Transcriptome Revealed Regulation of Different Nitrogen Concentrations on Hybrid Poplar Cambium Development.

ABSTRACT: Secondary development is a key biological characteristic of woody plants and the basis of wood formation. Exogenous nitrogen can affect the secondary growth of poplar, and some regulatory mechanisms have been found in the secondary xylem. However, the effect of nitrogen on cambium has not been reported. Herein, we investigated the effects of different nitrogen concentrations on cambium development using combined transcriptome and metabolome analysis. The results show that, compared with 1 mM NH₄NO₃ (M), the layers of hybrid poplar cambium cells decreased under the 0.15 mM NH₄NO₃ (L) and 0.3 mM NH₄NO₃ (LM) treatments. However, there was no difference in the layers of hybrid poplar cambium cells under the 3 mM NH₄NO
