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 ...

Text Book Of Botany Diversity Of Microbes And Cryptogams
Antheridia occur singly or in groups within closed cavities, known as antheridial
chambers. These chambers develop on the dorsal surface of the thallus, but they
do not open on the surface of the thallus. A superficial dorsal cell, lying close to ...

This is an example of control of antheridial differentiation by negative
photoresponse mediated through phytochrome. Antheridial differentiation in dark
is also known in Onoclea sensibilis. The pro thai li of Onoclea do not form
antheridia ...
The outer cell functions as an antheridial initial, whereas the inner cell again
divides periclinally., Three cells are formed (Fig. 9. 103B), of which the lowermost
remains as an internodal cell, middle one forms the basal node of the
antheridium, ...

gives rise to the antheridium proper, is called antheridial initial. A mucilage filled
space that develops between the antheridial initial and roof initial later enlarges
to form the antheridial chamber (Fig. 3.4 C). The roof initial does not take part in ...

University Botany I : (Algae, Fungi, Bryophyta And Pteridophyta)
Antheridia are formed in groups in antheridial cavity. Rarely only one antheridium
develops in an antheridial cavity e.g. A. himalayansis (Fig. 3.3 J & K). Antheridia
are 'endogenous' in origin. The cell adjacent to apical cell on the dorsal side of ...
Chemotmpic growth of antheridial hyphae and delimitation of antheridia. 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 ...

Couch (1926) interpreted the production of antheridial hyphae and oogonial
initials on male and female mycelia of Dictyuchus monosporus at points some
distance from the zone of contact and the growth of antheridial hyphae towards
the ...
