Seedling phenotypes of plants expressing SAUR63:YFP:HA variants

Abstract

A) Cotyledon area of seedlings of indicated genotypes grown on vertically oriented plates for 7d in long days in the absence (open bars) or presence (filled bars) of 1% sucrose. B) Root length of seedlings of indicated genotypes grown on vertically oriented plates for 4d in long days in the absence (open bars) or presence (filled bars) of 1% sucrose. C,F) Hypocotyl lengths (E) and hypocotyl tortuosity index [F, 1 –(distance between ends)/(contour length)] of seedlings grown on vertically oriented plates for 3d in darkness without sucrose. D) Cotyledon areas of P35S:SAUR63 and P35S:CBL11-12:SAUR6326-142 seedlings grown for 6d on vertically oriented MS 1% Suc plates. E) Hypocotyl lengths of P35S:SAUR63 and P35S:CBL11-12:SAUR6326-142 seedlings grown for 4d on vertically oriented 0.5x MS plates. Panels D and E show data for the three homozygous single-locus P35S:SAUR63 lines that differed most from wild type among seven lines analyzed. Graphs show means ± s.d. Letters in graphs indicate statistical classes based on Tukey’s Honestly Significant Difference test. n, from left to right: panel A: 26, 20, 25, 15, 22, 23, 24, 20, 22, 23, 19, 19, 21, 19, 21, 20; panel B: 19, 16, 18, 14, 20, 20, 21, 16, 21, 17, 19, 16, 18, 15, 16, 17; panel D: 77, 18, 17, 17, 19, 20; panel E: 119, 25, 24, 27, 21, 24; panels C and F: 35, 36, 45, 43, 47, 38, 41, 47.
