Fig. 4: Flower morphology and the expression patterns of regulatory genes of different mutants of C. ensifolium.

a Wild-type flowers and the expression patterns of regulatory genes²⁴. b Branched inflorescence with multitepal flowers and the expression patterns of regulatory genes. c Peloric flower mutant and the expression patterns of regulatory genes. d Column-like petal mutant and the expression patterns of regulatory genes. e Lip-like petal mutant and the expression patterns of regulatory genes. f Lip-like sepal mutant and the expression patterns of regulatory genes. Se, sepal; Pe, petal; Li, lip; Co, column. The rectangles of different colors (blue, red, green, yellow, pink, orange and gray) indicate that the genes were expressed in the floral organs, while a white rectangle indicates that the gene was not expressed or was expressed at a low level in that floral organ.
