↵F1-b GUS expression in roots, as assessed by histochemical staining.
↵F1-c GUS activity per milligram of protein in the mutant relative to the wild type within a common pool of F2 seedlings containing the indicated GL2promoter::GUS fusion. Values are means ± sd.
↵F1-d +, Typical qualitative pattern of GUS expression detected.
↵F1-e −, No GUS expression detected.
