Growth of strains with fructose. The strains indicated for each panel were grown in AA/8 without fructose and then diluted in medium containing the concentrations of fructose indicated by the symbols on day 0. (A) Strains FD (A. variabilis wild type) (solid symbols) and BP301 (frtR mutant) (open symbols). (B) Wild-type strain FD. (C) A. variabilis BP301 (frtR mutant). (D) Anabaena sp. strain PCC 7120 with the frtRABC genes (strain BP291). (E) Anabaena sp. strain PCC 7120 with the frtABC genes (lacking frtR) (strain BP292). (F) Strain JU377, a strain of A. variabilis in which the frtABC genes are constitutively expressed from the strong psbA promoter. (G) Wild-type strain FD grown in the dark. (H) Anabaena sp. strain PCC 7120 with the frtRABC genes (strain BP291) grown in the dark. Fructose concentrations were as follows: ▾, 0 mM; ▪, 1 mM; ⧫, 5 mM; +, 10 mM; •, 50 mM; and ▴, 200 mM.
