Plant nutrition: root transporters on the move.
Nutrient and water uptake from the soil is essential for plant growth and development. In the root, absorption and radial transport of nutrients and water toward the vascular tissues is achieved by a battery of specialized transporters and channels. Modulating the amount and the localization of these membrane transport proteins appears as a way to drive their activity and is essential to mainta...

متن کاملRoot patterning: SHORT ROOT on the move
The radial pattern of the plant root is determined by the action of two transcription factors, SHORT ROOT and SCARECROW, which are produced in different cell types. The SHORT ROOT protein has now been shown to move from cell to cell, regulating transcription of the downstream SCARECROW gene in the target cells.
متن کاملIon channels and transporters on the move.
Cell migration plays a crucial role in a variety of (patho)physiological processes such as immune defense, wound healing, and formation of tumor metastases. Detailed models have been developed to describe cytoskeletal mechanisms of migration. However, evidence is accumulating that the activity of ion channels and transporters is also required for optimal cell locomotion.
متن کاملUbiquitination of transporters at the forefront of plant nutrition.
In plants, the tight regulation of plasma membrane transporters is essential to maintain nutrient homeostasis. The mechanisms controlling the abundance of transporters, and other integral plasma membrane proteins, now come to light. Ubiquitination appears as a major signal initiating cargo endocytosis and sorting into multivesicular bodies prior to degradation in the vacuole. We have indeed dem...
