摘要

The understanding of capitulum morphogenesis is critical for modification of chrysanthemum flower type. Previous studies showed candidate genes which involved in the inflorescence architecture, such as PIN-FORMED 1 (PIN1), AUXIN RESPONSE FACTOR 5 (ARF5) and LEAFY (LFY), acted dominant role during early flower development. However, it is not known whether those candidate genes play parts in the capitulum morphogenesis. In the present study, floral morphogenesis and the corresponding external morphological changes in Chrysanthemum lavandulifolium were observed using scanning electron microscope and light microscope technology. Capitulum morphogenesis showed that ray florets primordia initiated later than the outermost disc florets primordia at the middle stage of florets primordia differentiation (stage 6), breaking the acropetal initiation of organ primordia on capitulum. Organogenesis of disc and ray florets showed that the early generation of florets corollas primordia was the key differentiation stages, in which disc and ray florets fused with actinomorphic and zygomorphic corollas, respectively. Furthermore, the expression patterns of inflorescence architecture related genes were detected at key stages of capitulum morphogenesis as well as the different organs on capitulum using quantitative real time PCR (qRT-PCR). The transcripts of ClARF5 specially increased at stage 5 and stage 6, as well as in ray florets corollas. The results indicated that ClARF5 might be responsible for the orientation and initiation of disc and ray florets during early capitulum morphogenesis. Studies on the capitulum morphogenesis of C. lavandulifolium not only bring molecular insights into capitulum morphogenesis, but also lay foundation for the flower type-oriented modification in cultivated chrysanthemums.
