FIG. 2.

Dominant microcystin variants produced by seven Anabaena strains. The y axis represents the relative proportion (%) of each microcystin variant out of all variants of each strain produced. Strains BIR246, BIR250A, BIR257, BIR258, BIR260, and 318 produced the same dominant variants, whereas the microcystin pattern produced by strain 315 was different. Variant A, [d-Asp³]MCYST-HtyR; variant B, MCYST-HtyR, variant C, [d-Asp³]MCYST-LR; variant D, MCYST-LR; variant E, [d-Asp³, Dha⁷]MCYST-HtyR; and variant F, [Dha⁷]MCYST-HtyR.
