Review: Nitrogen sensing in plants ($)

Like other organisms, plants have developed mechanisms to sense and respond to changes in the availability of nutrients. Nitrogen (N), being very essential for the growth and development of plants, must also be strongly monitored by plants. N sensing and signaling in plants are highly researched topics, but uncertainty remains in the nature of N-sensing mechanisms for controlling N uptake and plant development. In this review, Gent and Forde discuss potential N sensing molecules and pathway including glutamine, TOR complex and GLR family of glutamate-like receptors (GLRs).  (Summary by Mather Khan) J. Exp.
