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 ...

Stem apices of Anacharis densa were fixed, sectioned at 40 g, and stained in Feulgen and in ruthenium red. The three-dimensional shapes of 400 cells in various stages of division in the interior of ...

As global temperatures continue to rise, extreme heatwaves pose a significant threat to agricultural productivity. Studies estimate that for every 1°C increase above pre-industrial levels, crop yields ...

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 ...
