The filamentous cyanobacteria Symploca PCC 8002 (Symploca) and Trichodesmium spp. fix nitrogen aerobically in the light in a light/dark cycle, without forming specialized thick-walled cells (heterocysts). Even though they do not form heterocysts, we amplified and sequenced a segment of a key regulatory gene in heterocyst differentiation, the hetR gene, from Symploca, Trichodesmium erythraeum and Leptolyngbya PCC 73110 (which fixes nitrogen anaerobically) using degenerate oligonucleotides. The… CONTINUE READING
