Fig. 1. Effects of Xcl1 on leaf morphology. (A) Wild-type seedling. (B) Xcl1 seedling has narrow, thick leaves that are shiny in appearance. Scale bars 2 cm. (C-E) Morphometric analysis of adult leaves (numbered from top of plant down) in the Tama Flint (Blue), W23 (Red) and B73 (green) backgrounds. Wild-type values are solid bars and Xcl1 values are hatched. (C) In all backgrounds, Xcl1 leaves are significantly shorter than wild-type leaves. (D) At the midpoint of the leaf blade, Xcl1 leaves are half as wide as wild-type leaves. (E) At the midpoint of the leaf blade, Xcl1 leaves are twice as thick as wild type. Similar width and thickness effects were seen at 1/4 and 3/4 the length of the blade.
