Long term nitrogen effect in hybrid aspen (Populus tremula x P. tremuloides)
Nitrate is an important nutrient source and is often a limiting factor in plant growth and development. On the contrary, an excessive amount can limit its usage efficiency by plants and pollute the ecosystem, necessitating the exploration of nitrogen usage and accumulation in plants. This study analyzed the physiological, biochemical, and molecular features of nitrate responses in wood under three concentration levels (high, medium, and low) of nitrate. The differential gene expression among the selected concentrations was determined by RNA Seq of xylem tissue isolated from hybrid aspen.
