Systematics and Evolution
O. The Oogonium The oogonial initial develops as a swelling without septation or
by a transformation of a gametangial segment. The first trigger for this
morphogenetic change must be endogenous, from either a nutritional or
biochemical ...

Fish Histology: Female Reproductive Systems
In lampreys, possibly all elasmobranchs, and some bony fishes, oogonial
proliferation is limited to the larval or embryonic period (Tokarz, 1978).
Successive generations of oocytes appear to develop from oogonia in the
germinal ridge of adult ...

Cryptogams: Algae, Bryophyta and Pterldophyta
The smaller lower one is called the stalk cell and the upper longer one is called
the oogonial cell (Fig. 12.9 B). The stalk cell does not divide further. The oogonial
cell gradually increases in size and becomes almost spherical. It contains dense
...
The oogonial initials now secrete Hormone C, which directs the growth of the
antheridial hyphae to the oogonial initials and also causes the formation and
delimitation of the antheridia after the antheridial hyphae make contact with
oogonial ...

antheridial hyphae to the oogonial initials and also causes the formation and

However, intermediate strains have been discovered that produced either
antheridia or oo- gonia depending on the propensities of the opposed strain; that
is, they are antheridial in the presence of a strongly oogonial strain and oo-
gonial in ...
Effects of Pheromones. Oogonial mother spores secrete a sirenin; the
androspores are attracted by it and collect and adhere to these cells. If a capillary
is filled with the aqueous medium in which threads with oogonial mother cells
have been ...
Hans Mohr, Peter Schopfer, 1995
In A. colorata the oogonial wall bears blunt rounded projections (Fig. 7.9 D-E).
Each oogonium remains filled with dense homogeneous contents. The young
oogonial initial is multinucleatc and its nuclei keep on dividing for some time (Fig.

Text Book Of Botany Diversity Of Microbes And Cryptogams
It is attracted chemotactically towards the oogonial mother cell and gets attached
to it or any other adjacent cell by its anterior end. Then it germinates to form a
dwarf male. The dwarf male has a basal holdfast and one or more antheridia (Fig.
Following this sexual activation of the of plant, large lateral branches appear on
the 9 , and each of these rapidly enlarges to form a globose structure densely
packed with protoplasm, the oogonial initial or 9 sexual organ primordium. Once
