FIG. 2.

Survival of E. coli transformants which accumulate large or small amounts (0.27 or 0.14 mg/g dry weight, respectively) of zeaxanthin (Z-h, Z-l) or zeaxanthin diglucoside (Z-G) after treatment with UV-B at an intensity of 0.55 W/m². C-2 is a carotenoid-free control containing the same plasmids as the other transformants but without insertions of carotenoid genes.
