Minichromosome maintenance (MCM) proteins are subunits of the pre-replication complex that probably function as DNA helicases during the S phase of the cell cycle. Here, we investigated the function ...

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 ...

Plant stem cells, as in animals, are maintained in specialized microenvironments, which are known as stem cell niches, where local signals from organizer cells act to prevent stem cell differentiation ...
