Phenotype of overexpression mutants of CbuSPL9. a The change in floral organs occurred in the CbuSPL9-overexpressing transgenic Arabidopsis lines. Image of a normal flower from col. as the control (a/I); and the floral organ mutant from oespl9 (a/II-VI). a/II showing shrunken petals (White arrow) and increased stamens (Right arrow); a/III showing loss petal (White arrow); a/IV showing loss petal (White arrow); a/V showing increased petal (White arrow); a/VI showing overlapping petals (White arrow) and loss stamens (Right arrow); b Comparison of the flowering phenotype in both the col. and oespl9 transgenic plants. From top to bottom: col. (control) and oespl9 (transgenic plants). Bars = 2 mm in (a/II-VI), 1.5 cm in (b). c and d are the statistical data of the time of flower bud emergence and the number of rosette leaves. The oespl9 transgenic plants (black), the oe-hmga transgenic plants (gray) and the col. plants (white). A total of 30 plants were averaged to obtain the mean. Error bars indicate SD
