| gas vesicle genes in planktothrix spp. from nordic lakes: strains with weak gas vesicles possess a longer variant of gvpc. | in cyanobacteria of the genus planktothrix:, there are three length variants of gvpc, the gene that encodes the outer protein of the gas vesicle. sequence analyses indicated that the three allelic variants of gvpc differ principally in the presence or absence of a 99 nt and a 213 nt section. strains with the new variant, gvpc(28), which encodes a 28 kda form of gvpc, produce gas vesicles that collapse at the relatively low critical pressure (p(c)) of 0.61-0.75 mpa. the authors have identified 12 ... | 2000 | 10931905 |
