1
Plant meristems harbour stem cells, which allow for the continuous production of new organs.
2
Postembryonic development of plants depends on the activity of apical meristems established during embryogenesis.
3
There is a stringent requirement to couple these processes in shoot and root meristems.
4
Transgenic lines also displayed abnormal shoot apical meristems (SAMs) and retarded growth at the vegetative stage.
5
As cells pass through meristems, they transit through zones with high rates of cell growth and proliferation during organogenesis.
6
In plants, all organs are ultimately derived from a few pluripotent stem cells localized in specialized structures called apical meristems.
7
Because soil efficiently insulates meristems from the heat of fire, concealing buds below ground provides fitness benefits in fire-prone ecosystems.
8
The gene is expressed in both vegetative and floral meristems, in leaf primordia and leaves, and in the four floral organs.
9
Reduced expression of OsCKX2 causes cytokinin accumulation in inflorescence meristems and increases the number of reproductive organs, resulting in enhanced grain yield.
10
The development of meristems involves a coordinated balance between undifferentiated growth and differentiation, a phenomenon requiring a tight regulation of gene expression.
11
Three recent studies have uncovered effector mechanisms and novel pathways in the regulation of the dynamic changes to cell behaviour that occur in plant meristems.
12
The maize mutant rum1 (rootless with undetectable meristems 1) does not initiate seminal roots and lateral roots in the primary root.
13
In the meristem zone, meristematic cell division potential was reduced by excess Cu.
14
Candidate genes involved in meristem development, cell wall modification and transcriptional regulation were detected.
15
A SUP-dependent flower meristem termination pathway is identified and analysed.
16
The shoot apical meristem (SAM) gives rise to all aerial plant organs.
