In plants, postembryonic formation of new organs helps shape the adult organism. This requires the tight regulation of when and where a new organ is formed and a coordination of the underlying cell divisions. To build a root system, new lateral roots...

Phosphate (P) is an essential macronutrient for plant growth. Roots employ adaptive mechanisms to forage for P in soil. Root hair elongation is particularly important since P is immobile. Here we report that auxin plays a critical role promoting root... Read More about A mechanistic framework for auxin dependent Arabidopsis root hair elongation to low external phosphate.

Formation of the stomatal outer cuticular ledge requires a guard cell wall proline-rich protein (2017)
