Taxonomy
The genus Spirogyra was named by German naturalist Johann Heinrich Friedrich Link in 1820. The lectotype, Spirogyra porticalis was designated in 1952 by Paul C. Silvia.
Reproduction
Spirogyra can reproduce both sexually and asexually. In vegetative reproduction, fragmentation takes place, and Spirogyra simply undergoes intercalary cell division to extend the length of the new filaments.
Sexual reproduction is of two types:
- Scalariform conjugation requires association of two or more different filaments lined side by side, either partially or throughout their length. One cell each from opposite lined filaments emits tubular protuberances known as conjugation tubes, which elongate and fuse to make a passage called the conjugation canal. The cytoplasm of the cell acting as the male travels through this tube and fuses with the female cytoplasm, and the gametes fuse to form a zygospore.
- In lateral conjugation, gametes are formed in a single filament. Two adjoining cells near the common transverse wall give out protuberances known as conjugation tubes, which further form the conjugation canal upon contact. The male cytoplasm migrates through the conjugation canal, fusing with the female. The rest of the process proceeds as in scalariform conjugation.
The essential difference is that scalariform conjugation occurs between two filaments and lateral conjugation occurs between two adjacent cells on the same filament.
Usage
Spirogyra species are being researched for their potential in bioremediation. Specifically, in stemming toxic runoff from mines (where they are often found occurring naturally) and from municipal wastewater. Spirogyra has also been investigated as a potential biofuel.
Spirogyra species, such as S. varians, are also being researched for potential pharmaceutical usage due to their high nutrient densities.
