Meristem - Wikipedia
In cell biology, the meristem is a type of tissue found in plants. It consists of undifferentiated cells (meristematic cells) capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants. These cells continue to divide until they become differentiated and lose the ability to divide.
The boundary of the meristematic and elongation zones in roots …
2013年10月14日 — Plant roots consist of a meristematic zone of mitotic cells and an elongation zone of rapidly expanding cells, in which DNA replication often occurs without cell division, a process known as ...
30.11: Plant Development - Meristems - Biology LibreTexts
2023年10月31日 — The apical meristem (the growing tip) functions to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds. The apical meristem is organized into four meristematic zones: (1) central zone, (2) peripheral zone, (3) medullary meristem and (3) medullary tissue.
Meristem | Definition, Function, Types, Examples, & Facts
Meristem, region of cells capable of division and growth in plants. Meristem cells are typically small cells the diameters of which in different directions are about equal. They have a dense cytoplasm and relatively few small vacuoles (watery saclike enclosures).
RGF1 controls root meristem size through ROS signalling
2019年12月4日 — Root growth arises through controlled cell division in the root’s meristematic zone (equivalent to the transit amplifying zone in animals). After division, most cells increase their size in the...

2013年10月14日 — Plant roots consist of a meristematic zone of mitotic cells and an elongation zone of rapidly expanding cells, in which DNA replication often occurs without cell division, a process known as endoreduplication.

2021年4月6日 — Root development relies on the establishment of meristematic tissues that give rise to distinct cell types that differentiate across defined temporal and spatial gradients.
Function and regulation of transcription factors involved in root ...
2015年7月5日 — The RAM can be divided into three main zones: (a) the meristematic zone at the root tip containing the stem cell niche, (b) the elongation zone, containing the cells that after cell divisions have left the meristematic zone and are now elongating, and (c) the differentiation zone, containing cells that have acquired their destined cell fates.
The Root Transition Zone: A Hot Spot for Signal Crosstalk
2018年5月1日 — The root transition zone (TZ), located between the apical meristem and basal elongation region, has a unique role in root growth and development. The root TZ is not only the active site for hormone crosstalk, but also the perception site for various environmental cues, such as aluminum (Al) stress and low phosphate (Pi) stress.
A Definition of Meristematic Tissue in Plant Biology - ThoughtCo
2019年1月17日 — In plant biology, the term "meristematic tissue" refers to the living tissues containing undifferentiated cells that are the building blocks of all specialized plant structures. The zone where these cells exist is known as the "meristem."
