Anabaena cf. willei Gardner (1927: 60) Fig. 40 A–H. Filaments single, growing amongst other algae, or in fine, unstructured mats on the benthos. Trichomes straight, not or slightly attenuated towards the ends, constricted at the cross walls. Vegetative cells cylindrical to barrel-shaped, 0.6–1.3 × longer than wide, 3.5–8.0 μm long × 4.3–5.5 (–6.5 ...

Hydrogen uptake by Azolla-Anabaena
Plant and Soil, 1987Experiments under laboratory conditions were carried out with the objective of studying hydrogen uptake in the Azolla-Anabaena system. Tritium was used as tracer and plants were incubated under different atmospheric composition: a) Air+3H2; b) Air+3H2+CO; c) Air+3H2+CO, d) Argon+3H2+CO2+CO and in presence and absence of light, to study hydrogen uptake ...

Anabaena augstumalis Schmidle 1900
2018Anabaena cf. augstumalis Schmidle (1900: 174) Fig. 36 E–F. Filaments benthic, epiphytic, solitary, or clustered together into small mats. Trichomes flexuous, with fine, indistinct mucilage, cylindrical, constricted at the cross walls, not attenuated towards the ends. Vegetative cells barrel-shaped to shortly cylindrical, isodiametric, or up to 1.6 ×

THE ROLE OF ANABAENA IN THE AZOLLA‐ANABAENA SYMBIOSIS
New Phytologist, 1977SUMMARYThe Anabaena cells in Azolla undergo a developmental pattern of differentiation parallel to that of the fern. At the apex, the algal cells are small and rapidly dividing, and do not fix atmospheric nitrogen. After the leaf cavities are colonized, the algal cells form heterocysts, fix nitrogen and the vegetative cells enlarge considerably.

The nitrogen-fixing filamentous cyanobacterium A. thermalis SpA was isolated from the-surface of wild rice growing in Viet Nam. Electron microscopy shows that the purified strain is able to penetrate into the root interior of surface sterilized rice plants. Attempts have been initiated to genetically manipulate A.

2018Anabaena inaequalis Bornet & Flahault (1886: 231) Fig. 37 A–B. Filaments benthic, jointed into prostrate mats, less commonly tychoplanktonic; trichomes straight or slightly flexuous, sometimes in parallel fascicles, constricted at the cross walls, not attenuated towards the ends.

Heterocyst Differentiation in Anabaena ambigua
Biochemie und Physiologie der Pflanzen, 1976Summary The undifferentiated algal filaments of Anabaena ambigua Rao were exposed to N-methyl-N'-nitro-N-nitrosoguanidine (NTG), and UV-irradiation during the induction period of heterocyst formation. NTG has been observed to inhibit the heterocyst differentiation by affecting the enzyme level.
