Phenotypes associated with an “enhanced sensitivity to sulfamethoxazole (Smex)” mutant (ESS 3–10). (a) Seedling growth phenotype of ESS 3–10 on media containing 0.5 μM Smex. The T-DNA insertion line CS26759 (in a Landsberg erecta background) is shown for comparison. Scale bar represents 1 cm. (b) Seedling growth phenotypes of ESS 3–10 on media containing both p-aminobenzoic acid (PABA) and 0.5 μM Smex. Both images were captured after 14 days of growth. (c) Gene model of At2g23470. Black regions indicate open reading frames while white areas designate untranslated regions. The location of the point mutation mapped in this study for ESS 3–10 is indicated by an asterisk, and the specific sequence change is shown at both the nucleotide (nt) and amino acid (aa) levels. An inverted triangle denotes the approximate location of the T-DNA insertion (stock CS26759) used to confirm the ESS phenotype.
