Flower development is an important integrated developmental process in the life cycle of angiosperms, involving the transition from infinite to finite growth and different developmental modes, including flowering induction, signaling, attribute determination, and organogenesis, which is both induced by environmental factors and regulated by its own internal factors, through a series of signal transduction processes to initiate the control genes in the flowering decision process. Under the regulation of a complex network of gene interactions, the vegetative meristem (VM) transforms into inflorescence meristem (IM), and then flanks the IM to form floral meristem (FM), which differentiates into floral organs.
