nest in the germinal epithelium, bar = 70 [micro]m.
El bajo porcentaje de ejemplares en transicion con vestigios de gametos masculinos y oogonias
, coincide con reportes usualmente menores al 1% (Pouvreau et al, 2000; Saucedo et al, 2002; Kimani et al, 2006).
By homology, we believe that the upregulation of IL-1-like molecules in the hyperplasic ovary may induce the proliferation of neoblasts and their differentiation in oogonia
, but may inhibit their maturation, causing the pathology of infertility.
The Phytophthora taxonomic system has been based on morphological characteristics of the globose oogonia
with paragynous antheridia, chlamydospore, torulose hyphae and lemon shape of sporangia (Mchau and Coffey, 1995).
spermatogonia and Only oogonia
and primary primary spermatocytes are growth oocytes are present.
The quantity of Characeae oogonia
is in its maximum.
For ovaries, we counted oogonia
and oocytes in sections stained with hematoxylin and eosin.
Developing spermatogonia and oogonia
have two functional centrioles (diplosomes) in their centrosomes, showing the typical "9+0" organization of microtubule triplets --common to all somatic cells.
Eventually, the primordial germ cells will develop into oogonia
and ultimately become oocytes, whereas the mesenchymal cells within the membrane will become granulosa cells.
A thallus could be asexual, and produce zoospores; could be a sexual male, and produce sperm (Samenkrrper); or be a sexual female, and produce oogonia
1996) e MOORE-LANDECKER (1996) afirmam que, para realizar-se a correta identificacao do Pythium insidiosum, e necessario observar-se as caracteristicas morfologicas dos zoosporangios, zoosporos, oogonia
They were found as parasitic on oogonia
of an unidentified species of the genus Achlya.
