About this Research Topic
Plants have a remarkable capacity to adjust their architecture and body plan post-embryonically. To do this, plants maintain stem cells at the tips of their bodies, or apical meristems, to continuously generate new organs throughout their lifespan. Their aboveground architecture is determined by the shoot apical meristem (SAM), which harbors stem cells that generate all shoot organs such as stem, leaves and flowers depending on developmental and environmental factors. Despite the differences in architecture between species, common regulatory networks determine maintenance and patterning of the SAM.
Recent studies have identified some of the pathways that integrate environmental signals to control meristematic activity. The present Research Topic focuses on new advances in the molecular, genetic and cellular mechanisms that link shoot meristematic activity with biotic or abiotic factors.
We welcome Original Research articles, Reviews, Methods, among others, around topics including:
• Hormonal interactions controlling meristem activity.
• Environmental factors regulating meristematic activity.
• Functional characterization of conserved regulators of shoot apical maintenance in evolution.
