qPCR of selected genes with a stronger expression in adaxial petals. Expression analysis via qPCR was carried out on from two (A-C, replicate 3, replicate 4) and three (D–I, replicates 5–7) different biological replicates. (A) RALF-like 15, (B) RALF-like 19, (C) COB-like 10, (D) PETAL LOSS, (E) IaTCP1, (F) P-glycoprotein 13, (G) cytokinin oxidase 3, (H) Rcd1-like and (I) a contig with homology to a protein of unknown function (At5g42680). aBp, abaxial petal; aDp, adaxial petal.
