Fig. 4From: Phalaenopsis orchid miniaturization by overexpression of OsGA2ox6, a rice GA2-oxidase genePhenotypic comparisons of roots of the NT and GA2ox6-OX transgenic lines. a Three plantlets of NT control plants showing longer roots. b Three plantlets from each of the four GA2ox6-OX transgenic lines (#1-1, #3-2, #3-3, and #3-4) showing shorter roots. Bar = 12 cm. c Comparison of the lengths and widths of roots dissected from the NT line and representative GA2ox6-OX transgenic line #3-3 are shown. The ranges of root length and average root width measured for the dissected roots are provided below the picturesBack to article page
