Quiescence (noun) is a labile state of a cell, embryonic or meristematic structure, where division of the cell or cell population is repressed by non-cell-autonomous processes. Cell division may not have ceased or stalled, and evidence suggests that mitosis continues even in stem cell populations.

WebThese meristematic cells have made a way in determining the number, proliferative activity and lifespan, and potency of the cells in the shoot meristem. Apical meristem is responsible for the overall length of the plant. During cell division, apical meristematic cells produce new meristematic cells that exist in the shoot tip and root system. WebThe shoot system consists of two portions: the vegetative (non-reproductive) parts of the plant, such as the leaves and the stems, and the reproductive parts of the plant, which include flowers and fruits. The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis. WebJul 11, 2016 · In seed plants, these new meristems initiate in leaf axils to enable lateral shoot branching. Using live-cell imaging of leaf axil cells, we show that the initiation of axillary meristems requires a meristematic cell population continuously expressing the meristem marker SHOOT MERISTEMLESS (STM). create your own publishing company
