In higher plants, meristems are responsible for the generation of all plant tissues and organs. While the shoot apical meristem (SAM) gives rise to all of the above-ground plant parts for the entire ...

Mutually repressive interactions between KNOX proteins and AS1 and AS2 proteins contribute to the delimitation of leaf founder cells in the shoot apex of Arabidopsis. ARP MYB-like proteins are ...

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 ...
