Media Supplements

Induction and maturation of the sexual oospores of the facultative mosquito parasite Lagenidium giganteum (Oomycetes: Lagenidiales) are influenced by exogenous lipid media supplements. Sterols structurally related to cholesterol are necessary for induction of sexual reproduction and possibly have at least a structural role in oospore maturation following spore wall formation. Sterols also enhance uptake of certain exogenous fatty acids from growth media. Palmitoleic, oleic, and linoleic acids, especially when added to media as triacylglycerols, enhance oospore induction and maturation. It is hypothesized that enrichment of the fatty acyl compounds of the fungus with unsaturated moieties affects cyclic nucleotide metabolism and promotes cellular and vesicular fusion events associated with oosporogenesis by regulating (increasing) membrane fluidity. Results are discussed in relation to mediation of fusion events in a number of diverse model membrane and biological systems by fatty acids and sterols.

Identification of Spirogyra species is based on the morphology of the fertile specimens. This work provides characteristics of growth and the time of reproduction of Spirogyra decimina var. juergensii in Lake Baikal and describes sexual reproduction and conditions for germination of new filaments of this species isolated from the lake.

Key Terms

The absence of a conceptual terminology, sufficiently developed and widely accepted in the Russian literature, significantly hinders progress in the field of reproductive biology of diatoms, restricts communication and debate, prevents training and transfer of knowledge. The present work is an attempt, based on world literature and our own research experience, to summarize, systematize, add, and clarify the existing terms, concepts and definitions related to research which are focused on sex and sexual reproduction in diatoms. A glossary of key terms (more than 200, including synonyms) is provided. Terms refer to diatom reproductive biology, life cycles, fertilization, mating system, gender (including inheritance and determination of sex, as well as inheritance associated with sex). Contradictions between possible interpretations of certain terms are briefly discussed.
