On the left, a young Arabidopsis plant is shown, with one of the root tips indicated by the yellow line. The yellow box shows a virtual section through a three-dimensional reconstruction of the root ...

Rhizophores arise from angle meristems located at shoot branch points in many species of Selaginella and produce roots at their distal ends. We reinvestigated the origin and development of rhizophores ...

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 ...

Plants can acclimate by using tropisms to link the direction of growth to environmental conditions. Hydrotropism allows roots to forage for water, a process known to depend on abscisic acid (ABA) but ...

Some species of Cactaceae from the Sonoran Desert are characterized by a determinate growth pattern of the primary root, which is important for rapid lateral-root formation and seedling establishment.

Researchers have used 3D live imaging to observe the formation process of lateral roots in plants, and clarified part of the mechanism that creates new meristematic tissue. If the root formation ...
