From: An integrated QTL and RNA-seq analysis revealed new petal morphology loci in Brassica napus L.
The model of B. napus petal morphology variation. The accumulation of GAs and zeatin could promote the cell proliferation of petals, and the accumulation of GAs and IAA could promote the cell expansion of petals, resulting in petal size variation. Meanwhile, the cytoskeleton could affect the cell polarity of division and expansion, potentially leading to slender petals. The heat map was drawn using the log2(fold change) of FPKM of certain genes between specific samples that were detailedly annotated at the bottom, and the matchup of heat map cubes and samples was also annotated at the bottom
