Stem cell function during plant vascular development.
The plant vascular system, composed of xylem and phloem, evolved to connect plant organs and transport various molecules between them. During the post-embryonic growth, these conductive tissues constitutively form from cells that are derived from a lateral meristem, commonly called procambium and cambium. Procambium/cambium contains pluripotent stem cells and provides a microenvironment that ma...
متن کاملCell-cell interactions during plant development.
The large body of information that has come from genome sequencing projects has demonstrated that plants and animals have many sequences in common, suggesting that they have either co-opted the same molecules for different purposes, or that they utilize similar mechanisms (Reuzeau and Pont-Lezica 1995; Clark 1996). One might expect many housekeeping tasks, such as regulation of the cell cycle, ...
متن کاملVascular signalling mediated by ZWILLE potentiates WUSCHEL function during shoot meristem stem cell development in the Arabidopsis embryo.
Stem cells are maintained in an undifferentiated state by signals from their microenvironment, the stem cell niche. Despite its central role for organogenesis throughout the plant's life, little is known about how niche development is regulated in the Arabidopsis embryo. Here we show that, in the absence of functional ZWILLE (ZLL), which is a member of the ARGONAUTE (AGO) family, stem cell-spec...
متن کاملPlant stem cell niches.
Stem cells are required to support the indeterminate growth style of plants. Meristems are a plants stem cell niches that foster stem cell survival and the production of descendants destined for differentiation. In shoot meristems, stem cell fate is decided at the populational level. The size of the stem cell domain at the meristem tip depends on signals that are exchanged with cells of the org...
متن کاملExosomes function in cell-cell communication during brain circuit development.
Exosomes are small extracellular vesicles that mediate intercellular signaling in the brain without requiring direct contact between cells. Although exosomes have been shown to play a role in neurological diseases and in response to nerve trauma, a role for exosome-mediated signaling in brain development and function has not yet been demonstrated. Here we review data building a case for exosome...
