Transcriptomic analysis reveals the formation mechanism of anemone-type flower in chrysanthemum.

ABSTRACT:

Background

The ray and disc florets on the chrysanthemum capitulum are morphologically diverse and have remarkably abundant variant types, resulting in a rich variety of flower types. An anemone shape with pigmented and elongated disk florets is an important trait in flower shape breeding of chrysanthemums. The regulatory mechanism of their anemone-type disc floret formation was not clear, thus limiting the directional breeding of chrysanthemum flower types. In this study, we used morphological observation, transcriptomic analysis, and gene expression to investigate the morphogenetic processes and regulatory mechanisms of anemone-type chrysanthemum.

Result

Scanning electron microscopy (SEM) observation showed that morphological differences between non-anemone-type disc flore
