Phenotype of overexpression mutants of CbuHMGA. a The change in floral organs occurred in the overexpression of the CbuHMGA transgenic Arabidopsis lines. The images are the floral organ mutant from oe-hmga transgenic Arabidopsis lines (a/I-VI). a/I showing shrunken petals (White arrow); a/II showing dislocation petals (White arrow) and separating stamens (Red arrow); a/III showing dislocation petals (White arrow); a/IV showing overlapping petals (White arrow); a/V showing increased petal (White arrow) and loss stamens (Red arrow); a/VI showing increased petals (White arrow); Bars = 2 mm in (a/I-VI). b Expression profiles of atSPL9 homologous genes in the oespl9 transgenic plants, oe-hmga transgenic plants and col. represents the PCR results in oe-hmga; represents the PCR results in oespl9; and represents the PCR results in col. Three independent biological replicates were performed, and each replicate was measured in triplicate. The error bars show the standard deviation of the results of three technical replicates
