Studies on Diuron Uptake in a Blue-Green AlgaNostoc muscorum

Journal of Experimental Botany (1984)

A. Vaishampayan

A mutant of Nostoc muscorum that is resistant to 3-(3.4-dichlorophenyl)- I.1-dimethylurea (diuron) has been selected. This mutant may lack the step in photosynthesis that is affected by diuron (DCMU). but it can also use DCMU as a source of carbon and nitrogen. Another mutant of this organism resistant to L-methionine-DL-sulphoximine (MSO), that was isolated previously, also shows some cross-resistance to DCMU.

Mutagenic activity of alachlor, butachlor and carbaryl to a N₂-fixing cyanobacteriumNostoc muscorum

The Journal of Agricultural Science (1985)

A. Vaishampayan

Summary Alachlor, butachlor and carbaryl were highly toxic to the N 2 -fixing cyanobacterium Nostoc muscorum , when grown on solid minimal (nitrogen-free) medium. At pesticides doses allowing about 20, 50 and 60% survival of the organism, various mutations were obtained in N. muscorum , reverse mutation from het + nif – and het – nif + auxotrophy to het + nif + prototrophy, forward mutation for resistance to 0·37 mM L-methionine-DL-sulfoximine, and auxotrophic mutation for the achievement of carbon-auxotrophy through 5 mM methylamine-resistance. The toxic and mutagenic effects of the three pesticides were similar to those of the well known mutagen MNNG.
