WebJul 2, 2024 · The classic phytohormone auxin plays an essential role in priming meristematic cell differentiation in the shoot apical meristem to promote lateral organ initiation. Recently, several lines of evidence have suggested that auxin is not only transported to new primordia but also descends to the stem cells in the central zone. Apical meristems are the completely undifferentiated (indeterminate) meristems in a plant. These differentiate into three kinds of primary meristems. The primary meristems in turn produce the two secondary meristem types. These secondary meristems are also known as lateral meristems because they are involved in lateral growth. Apical meristems are the completely undifferentiated (indeterminate) meristems in a plant. These differentiate into three kinds of primary meristems.

WebIn accordance with Luis Carlos Ramos, add that the shoot apical meristematic cells can not be considered totipotent, but, pluripotent because they are designed to develop most tissues of the plant ... 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).
WebMar 30, 2024 · Delineating quiescence and dormancy. 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. WebThis result suggested that ABA may negatively regulate the expression of CCG in meristematic tissues of grapevines. To test this proposition, the effect of ABA on the expression of CCG was analyzed in two meristematic tissues of the vine: somatic embryos and shoot apexes. ...
