The molecular mechanism regulating petal length in flowers is not well understood. Here we used transient transformation assays to confirm that  GhPRGL  (proline-rich and GASA-like)—a GASA (gibberellic acid [GA] stimulated in Arabidopsis) family gene—promotes the elongation of ray petals in gerbera ( Gerbera hybrida ). Yeast one-hybrid screening assay identified a bHLH transcription factor of the jasmonic acid (JA) signaling pathway, here named GhBPE (BIGPETAL), which binds to the  GhPRGL  promoter and represses its expression, resulting in a phenotype of shortened ray petal length when  GhBPE  is overexpressed. Further, the joint response to JA and GA of  GhBPE  and  GhPRGL , together with their complementary expression profiles in the early stage of petal growth, suggests a novel GhBPE-GhPRGL module that controls the size of ray petals. GhPRGL promotes ray petal elongation in its early stage especially, while GhBPE inhibits ray petal elongation particularly in the late stage by inhibiting the expression of  GhPRGL . JA and GA operate in concert to regulate the expression of  GhBPE  and  GhPRGL  genes, providing a regulatory mechanism by which ray petals could grow to a fixed length in gerbera species.
