The key to three-dimensional plant architecture lies in precise control over the orientation of cell division. Plant cells divide periclinally to grow radially—leading to thickening—while anticlinal ...

Plant development is governed by signaling molecules called phytohormones. Typically, in certain developmental processes more than 1 hormone is implicated and, thus, coordination of their overlapping ...

As the plant root grows, a root cap protects its fragile tip. Every few hours, the old cap is lost and a new one replaces it. This has puzzled scientists: how do cells at the tip know when to die, and ...

The role of calcium is well understood as a function of signaling between plants and symbiotic fungi that assist nitrogen fixation and phosphate uptake. Now a new study by researchers at the John ...

Mutations drive evolution, but they can also be risky. New research led by plant biologists at the University of California, Davis, published Nov. 10 in Proceedings of the National Academy of Sciences ...

• In rice, the florigens Heading Date 3a (Hd3a) and Rice Flowering Locus T 1 (RFT1), OsFD-like basic leucine zipper (bZIP) transcription factors, and Gf14 proteins assemble into florigen ...
