The study focused on the influence of light flux, because rapid and frequent changes are a feature of the light climate during the monsoon season. The response of nitrogenase to changes in light flux was quite rapid in the field and the lab. During one field study over a 24-h period lacking any long overcast period, only 3.7% of the total nitrogenase activity took place during the night. In batch culture, higher nitrogenase activity (per unit time) occurred for a period of about 12 h after a culture, which had been left in the dark for 12 h and had been re-illuminated, than the max. activity found under continuous illumination. The increase reached a max. of .apprx.100% after 3.5 h, and by 12 h this increased activity had made good 80% of the total activity lost by incubating the culture in darkness rather than light.

When inorganic nitrogen is available in the medium, the logarithmic phase of growth is prolonged and akinetes form at a higher culture density than when dinitrogen is supplied as the sole source of this element. Light quality also influences the timing of akinete differentiation; akinetes are formed at a lower culture density in green light in comparison to white light, particularly in the absence of combined nitrogen. These observations are interpreted in terms of the light energy requirement for the maintenance of growth and the spectral requirements for nitrogen fixation in cultures free of combined nitrogen. The data are related to the influence of variations in underwater light climate on the development of akinetes in natural populations of planktonic blue-green algae. Notes: 1986 English

Year: 1986 Title: Mutagenesis and Isolation of Morphological Mutants Impaired in Nitrogen-Fixing Capacity from a Cynaobacterium Gloeotrichia ghosei Journal: New Phytologist Volume: 103 Issue: 1 Pages: 69-77 Date: May Keywords: Cyanobacteria, Gloeotrichia ghosei, N-Methyl-N'-Nitro-N-Nitrosoguanidine, Ultra-Violet Irradiation, Nif$^-$ Mutant, Heterocyst, Nitrogen Fixation Abstract: Ultraviolet (u.v.) irradiation and treatment with nitrosoguanidine (NTG) were used to produce mutants of the cyanobacterium Gloeotrichia ghosei. Three non-nitrogen fixing (nif$^-$) mutants, which were also altered in their morphological characteristics, were isolated. They were designated as fil$^1$ het$^+$, fil$^1$ het$^++$ and pol$^-$ het$^-$. The first two mutants formed heterocysts and exhibited polarity while the third (i.e. pol$^-$ het$^-$) had neither heterocysts nor polarity. The fil$^1$ het$^+$ strain had a developmental pattern similar to that of the parent alga, but with longer filaments, while the fil$^1$ het$^{++}$ strain formed chains of intercalary heterocysts and the long filaments showed evidence of intercalary polarity. The isolation of these mutants demonstrates the feasibility of using Gloeotrichia to relate developmental morphology to nitrogen fixation and heterocyst differentiation in a filamentous cyanobacterium.

Original Publication: Vergleichsstudien and Gloeotrichia -Arten Accession Number: 1193339 Keywords: cell morphology; cultured organisms; nutritional requirements; Gloeotrichia Freshwater Q1 01223 Taxonomy and morphology Abstract: The morphological variability of some species in the genus Gloeotrichia was studied and compared with the cultures from the algal collections as well as the collected samples from natural environments. Inter-strain variations were not investigated but the inter-species variations were. Filaments with both heterocysts and akinetes belong to Gloeotrichia species, such as Gl. echinulata, Gl. longicauda and Gl. natans . The morphologically changed forms of one species in the nutrient-enriched cultures are very comparable with different described species living in the polluted waters. Some ecological co-relations between morphological changes and nutrient requirements are discussed. Notes: 1985 0342-1120 Referred to also as Algol. Stud. 38/39. German

Gloeotrichia echinulata: Vegetative cells, polarity, heterocysts, akinetes Journal: Br. Phycol. J. Volume: 19 Issue: 3 Pages: 259-275 Accession Number: 3906585 Keywords: cell morphology; phytoplankton; seasonal variations; ultrastructure; cytology; Gloeotrichia echinulata Freshwater Q1 01223 Taxonomy and morphology Abstract: Morphology, cytology and ultrastructure of vegetative cells, filament polarity, heterocyst differentiation and akinete development in Gloeotrichia echinulata are described under natural conditions for the first time by following wild populations of the alga over two successive field seasons. The ageing sequence of vegetative cells is studied in space and time by comparing cells from one end of a filament to the other and by comparing filaments through a complete cycle of growth and development. Heterocysts are characterized by massive sheaths and absence of membranous polar elaborations; healthy gas vesicles are retained in the heterocyst, even into senescence. Akinetes develop a "spore sheath" by modification of the filament sheath. As the akinete develops, a dense stratified deposit accumulates externally to the adjacent chain of meristematic cells. These become isolated and eventually detached, presumably as a hormogonial form of perennation. (DBO) Notes: 1984 0007-1617 English Journal Article Author Address: Dep. Plant Sci., Univ.
