	1	Transition from a maternal to external nitrogen source in maize seedlings显示文摘Maximizing NO_3^- uptake during seedling development is important as it has a major influence on plant growth and yield.However,little is known about the processes leading to,and involved in,the initiation of root NO_3^- uptake capacity in developing seedlings.This study examines the physiological processes involved in root NO_3^- uptake and metabolism,to gain an understanding of how the NO_3^- uptake system responds to meet demand as maize seedlings transition from seed N use to external N capture.The concentrations of seedderived free amino acids within root and shoot tissues are initially high,but decrease rapidly until stabilizing eight days after imbibition(DAI).Similarly,shoot N% decreases,but does not stabilize until 12–13 DAI.Following the decrease in free amino acid concentrations,root NO_3^- uptake capacity increases until shoot N%stabilizes.The increase in root NO_3^- uptake capacity corresponds with a rapid rise in transcript levels of putative NO_3^- transporters,Zm NRT2.1 and Zm NRT2.2.The processes underlying the increase in root NO_3^- uptake capacity to meet N demand provide an insight into the processes controlling N uptake.
