Reproductive Versatility in the Grasses
Archesporial tissue In angiosperm ovules the archesporial tissue is reduced to a
single cell, the megaspore mother cell, and there are no parietal cells. In
apomictic grasses there are a range of variants on this basic theme, since
nucellar tissue ...

anthers from self-pollinating and outcrossing anthers of Arenaria was first evident
at the end of this proliferative growth stage. Anthers from self- pollinating flowers

Botany For Degree Pteridophyta
The inner cell functions as the primary archesporial cell. The outer cell divides by
two intersecting walls into four primary wall cells which by further periclinal walls
forms a 4—6 layered thick sporangial wall. The primary archesporial cell also ...

cells differentiate as sporangial initials, which undergo periclinal divisions
forming an outer layer and inner layer of primary archesporial cells (Espamer,
1952, Fagerlind, 1961). The Cells of the outer layer divide only by the anticlinal
divisions ...

hypodermal region of the nucellus functions as the archesporial initial. The cell is
differentiated during the early stage of the development. The archesporial initial
is ...

Annual Plant Reviews, Fruit Development and Seed Dispersal
In Arabidopsis, the archesporial cell directly functions as the megasporocyte or
MMC (Reiser and Fischer, 1993). So far, little is known about the molecular
mechanisms underlying archesporial cell fate determination. In maize, the
multiple ...

Text Book of Botany: Angiosperms
The number of archesporial cells varies in different taxa. In Malvaceae and
Asteraceae there is only a single vertical row of archesporial cells, whereas in
some Lamiaceae, such as Mentha there is a layer of archesporial cells at each
corner.
