How a shape-shifting receptor influences cell growth

Receptors found on cell surfaces bind to hormones, proteins, and other molecules, helping cells respond to their environment. MIT chemists have now discovered how one of these receptors changes its shape when it binds to ...

Ammonium triggers formation of lateral roots

Despite the importance of changes in root architecture to exploit local nutrient patches, mechanisms integrating external nutrient signals into the root developmental program remain poorly understood. "Here, we show for the ...

Mechanism of jasmonate-promoted root hair growth in Arabidopsis

Root hairs are tubular polarized extensions of root epidermal cells and are crucial for plant anchorage, nutrient acquisition, and environmental interactions. The plant hormone jasmonate has been reported to promote root ...

New technique tracks individual protein movement on live cells

The piece of gold that Richard Taylor was thrilled to track down weighed less than a single bacterium. Taylor, a postdoctoral fellow at the Max Planck Institute, was working to follow individual nanogold-labeled molecules ...

SPEECHLESS, SCREAM and stomata development in plant leaves

Plants constantly make trade-offs in their decisions: more light means more opportunity for photosynthesis, but then hot temperatures and dry air makes wilting more likely. Stomata—microscopic valves on the surface of a ...
