Biology of the Red Algae
Peel and Duckett (1975) found these appendages to be of the same composition
as the spermatial coat. Magruder (1984) found that under very specific methods
of preparation, elaborate surface appendages could be demonstrated in Aglao- ...

Biocomplexity of Plant-Fungal Interactions
Outcrossing occurs during the haploid spermatial stage and, after receptive
spermatia fuse, dikaryotic aeciospores can be produced (Petersen 1974; Kirk et
al. 2001). Nuclear fusion and recombination occur later (after many months or
years) ...

An Introduction to Mycology
A relationship between the ascal and spermatial state of the Phyllachora —
Linochora relationship has been reported by Parbery (1978). According to him,
the species of Phyllachora parasitizing hosts in families such as the
Leguminosae ...

Sometimes, the presence of spermatial sori can be determined by placing some
male tissue in a petri dish and holding it against a dark background. Mature sori
can also be easily identified under a microscope along the edge of the thallus.

Fungi: Ascomycetes, Ustilaginales, Uredinales
No regular para- physes are produced but a few spermatial hyphae may
elongate and project as sterile threads (fig. 168 a). The spermatial hypha is a
long, narrow cell with a central elongated nucleus. It is furnished at its free end
with a ring of ...

Issues in Psychology and Psychiatry—Special Fields: 2013 Edition
In red algae, spermatial attachment to female trichogynes is mediated by a
specific binding between the lectin(s) distributed on the surface of trichogyne and
the complementary carbohydrates on the spermatial surface.” Our news

Red Algae in the Genomic Age
The species-specificity of such a glycoprotein was confirmed by immunological
studies (Jones et al., 1988, 1990). By considering the fact that spermatial binding
to trichogynes is not species- specific, but occurs between closely related species
...

Spermatial attachment to trichogynes according to spermatia/trichogyne ratio in
Aglaothamnion oosumiense. Results The female reproductive structure of
Aglaothamnion oosumiense is composed of four-celled carpogonial branches
with a ...

The trichogyne fuses with a spermatial element of the opposite mating-type.
Spermatia may be microconidia, macroconidia, or hyphae. The nucleus of the
spermatium enters and migrates through the trichogyne to the ascogonium,
forming the ...
