Knockout of OsGLP1 results in dwarfness and increased leaf inclination in rice plants grown under natural sunlight. In A, B, C, and D, the phenotype, plant height, root length and leaf angle (the second leaf from bottom to top), respectively, of WT, transgenic plants overexpressing OsGLP1 (2, 9, and 11) and glp1 mutants (3, 4, and 8) grown under natural sunlight until the 5-leaf stage are shown. In E, F, G, and H, the phenotype, plant height, root length and leaf angle, respectively, of WT, transgenic plants overexpressing OsGLP1 (2, 9, and 11) and glp1 mutants (3, 4, and 8) grown in a controlled growth chamber deficient in UV-B (12-h light, 600 µmol m⁻² s⁻¹, 30°C; 12-h dark, 28°C) until the 5-leaf stage are shown. The boxplots, from top to bottom, denote maximum value, upper quartile, median, lower quartile and minimum value, and whiskers denote maximum value to minimum value of the data. The means ± sd (n ≥ 16 plants) of plant height, root length or leaf angle assigned with different letters were significantly different as determined by one-way analysis of variance (ANOVA) with post hoc Bonferroni test (P < 0.05).
