Different phenotypes of leaves between wild-type and CsHMA3-overexpressing plants at the vegetative stage. Comparison of shape of leaves from four-week-old plants in hydroponic culture (A). Length of fifth leaf was measured in the leaf-length (longitudinal) and leaf-width (lateral) directions (B) and each leaf index was then determined by the ratio of length to width in a leaf blade (C). A value close to 1.0 is indicative of increased leaf roundness. Comparison of leaf angle (D). Each leaf angle was measured in the longitudinal and both lateral-end positions. Leaf count number (E). Leaves were collected from the same plants that were used for investigation of other leaf phenotypes. Measurement of stem length (F). Data represent means ± SD (n = 5). Different lowercase letters in the figure indicate significant difference at P < 0.05 by Tukey’s test.
