Abstract
FLOWERING LOCUS T (
FT) is an important factor for integrating flowering signals through the photoperiod pathway, which significantly promotes flowering. Most chrysanthemum varieties are short-day plants, sensitive to the photoperiod, which limits their ornamental and annual production supply. In this study, we aim to analyze the nutrients and flowering-related genes of chrysanthemums with different photoperiod types and to clone and verify the function of the flowering-related gene
CmFT. We found that the formation of floral buds requires the accumulation of starch while consuming soluble sugars and the expression patterns of flowering-related genes
GIGANTEA (
GI),
CONSTANS (
CO), and
FT in
C.morifolium ‘Zilian’ and
C. morifolium ‘Zihongtuogui’ had a certain synchronization during floral buds differentiation according to our quantitative validation, and the expression levels of
CmGI,
CmCO and
CmFT in
C. morifolium ‘Zihongtuogui’ were higher than those in
C. morifolium. ‘Zilian’ in the later stage of differentiation.
CmFT was cloned from photosensitive chrysanthemums-
C. morifolium ‘Zihongtuogui’ and polypeptide alignment and phylogenetic analysis showed that
CmFT was clustered in FT-like subfamily. In further functional verification, we obtained two
Arabidopsis transgenic lines. Our results showed that
CmFT transgenic ft mutant lines can significantly accelerate flowering in
Arabidopsis. Thus, we can initially confirm that
CmFT plays an important role in promoting flowering, which may be the key reason for the photosensitivity of
C. morifolium ‘Zihongtuogui’. Overall, the results of this study are of great importance in revealing the flowering mechanism of different photoperiod types of chrysanthemums.
