INTERNATIONAL REVIEW OF CYTOLOGY
But in the sixth division, in contrast to the fourth one, gonidial potential is passed
to the more posterior of the sister cells. Not shown in this figure is the fact that the
gonidial initials created at the sixth cleavage normally divide asymmetrically ...

But, again, it is extremely difficult to believe that such deviations from ideality
could be severe enough to result in nearly a 10-fold underestimate of DNA
content per gonidial nucleus, which is what would be required to explain the
discrepancy ...
The gonidial cells have larger number of protoplasmic connections with the
neighbouring somatic cells to get more of nourishment. The gonidial cells do not
retain their flagella. These gonidial cells are superficially alike but differ in their ...

Reproductive Biology of Plants
During embryogenesis, the embryos first cleave symmetrically five times to form a
32-cell embryo with identical cells, and then 16 cells divide asymmetrically to
each produce one large gonidial cell precursor and one small somatic cell ...

A Student's Text-book of Zoology: Protozoa to Chaetognatha
The mouth is usually slit-like, and the oesophagus has two gonidial grooves (
Gosse). Sometimes there is only one gonidial groove (Peachia, Zoantheae,
Ccrianttius). The thickened walls of these grooves are prolonged beyond the lip
at the ...

(B) In wild-type gonidia two types of gene expression are seen: (i) transcripts of
early gonidial genes (0) are maximally abundant at the beginning of cleavage
and then decline after the asymmetric division; (ii) transcripts of late gonidial
genes ...

LICHENS AND THEIR USES continued gonidial layer where most of the algal
cells, which are known as gonidia, are concentrated. Beneath the gonidial layer
is the medulla, a broad layer in which the hyphae are loosely arranged; this is ...

Handbook of Plant and Crop Physiology
In the small somatic initials, the regA gene is expressed and acts to suppress
expression of genes required for gonidial differentiation. These cells thus
become terminally differentiated as somatic cells. In the large gonidial initials,
meanwhile, ...

The large cells are gonidial initials that will produce one gonidium each, whereas
the small cells are somatic initials, each of which will divide symmetrically to
produce a clone of somatic cells. C) Gonidial initials divide asymmetrically a total
of ...
