Fatty acid metabolism in pex5 mutant seedlings. A, Hypocotyl length of seedlings grown for 24 h in light and 6 d in dark on medium supplemented with increasing concentrations of Suc. Error bars represent se (n ≥ 12). B, Hypocotyl length of seedlings grown for 24 h in light and 6 d in dark on medium without Suc or with 0.5% Suc. Error bars represent se (n ≥ 12). C, Hypocotyl length of seedlings grown for 24 h in light and 6 d in dark on medium without Suc or with 0.5% Suc. pex5-10 seed coats were nicked immediately after plating. Error bars represent se (n ≥ 12). D, Photographs depicting pex5-10 plant lines. Plants were grown on complete medium for 7 d. pex5-10 seed coats were nicked after plating. E, Percentage of C20:1 fatty acid (versus total fatty acids) in 6-d-old seedlings grown in light on 0.5% Suc medium. Error bars represent se of three biological replicates. Wt, Wild type.
