Development and reproduction of two species of the genus Volvox in a shallow temporary pool
نویسنده
چکیده
The reproduction and the formation of resistant dormant spores in Volvox aureus Ehr. and V. tertius Meyer were studied in a temporary pool during July–August 1996 and 1997. It has been shown that the populations of two species of Volvox (L.) Ehr. from this pool were characterized by different reproductive traits. Comparatively small quantity of male individuals and dormant zygotes (zygospores) episodically formed in the population of V. tertius. By contrast, in the population of V. aureus the formation of dormant parthenospores occurred and the male individuals were never observed. The ratio V. aureus : V. tertius was different in different years and underwent changes during one and the same summer.

Differentiation of reproductive structures and experimental sex change in Volvox (Chlorophyta, Volvocaceae)
This paper represents a brief review on current topics in both asexual and sexual reproduction of Volvox L., a green colonial freshwater alga, which is a valuable model of contemporary developmental biology of plants. In the case of asexual life cycle, the main attention is paid to published data on the mechanisms of differentiation into reproductive and somatic cells of Volvox carteri f. nagar...

In total 409 specimens of A. chalcoides, A. filippii, A. atropatenae, A. caeruleus, A. mossulensis, A. hohenackeri and A. zagrosensis were collected from Babolrud, Baleqlu-Chai, Miriseh, Sarabeleh, Gamasiyab, Mahabad-Chai Rivers and the Gandoman lagoon, respec...
متن کاملBroadening Gene Pool of Rice for Resistance to Biotic Stresses Through Wide Hybridization
Variability in the cultivated germplasm for economic traits such as resistance to rice tungro virus, sheathblight, yellow stem borer, drought and salt tolerance is limited. This necessitated search for the genes in secondary and tertiary gene pool of genus Oryza. Fortunately, wild species are an important reservoir ofuseful genes for resistance to major disease, pest and tolerance t...

Snow-fed river Pinder -a tributary of river Alaknanda in central Himalaya was explored for fish assemblages and habitat specificity. Altogether 27 fish species were reported from three orders, four families and nine genera. Cypriniformes order was dominating followed by Siluriformes and Salmoniformes. Shannon-Weiner diversity index (3.09 to 4.10) and Simpson index of diversity (0.81 to 0.92) of...
متن کاملComparative stepwise pattern of reactive oxygen species production during in vitro development of fertilized and nuclear transferred goat embryos
Objective A unique feature of embryo metabolism is production of reactive oxygen species (ROS). It is well established that during in vitro culture, ROS levels increase over normal ranges observed for embryos developed in vivo. This study evaluates and compares the stepwise pattern of ROS production during in vitro development of reconstructed goat embryos produced by zona-free method of somati...
