Thiazole-auxotrophic Arabidopsis thaliana plants can use cHET to sustain growth. Mutant tz-1 plants were grown with the indicated concentrations of HET or cHET. Pictures were taken 14 days after germination and are representative of at least 30 plants. A wild-type (WT) plant is shown for comparison.
