β-oxidation phenotypes of kat mutants. (A) Length of etiolated hypocotyls. Plants were grown in the dark for 4 d on 0.5× MS media supplemented with or without 1% (w/v) sucrose (n ≥14). (B) Inhibition of root growth in response to varying concentrations of 2,4-DB of thiolase mutants after 8 d growth (n ≥13). (C) Degradation of the TAG fatty acid marker C20:1 in Ws-4 and kat5-2 from 2–5 d post-stratification. Seeds were germinated on plates and 50 seedlings were collected at 24h intervals. In each panel, values represent mean ±SE (n=4).
