DNA demethylation during Chrysanthemum floral transition following short-day treatment

Background: Analytical techniques such as methylation-sensitive amplification polymorphism and high-performance liquid chromatography were used to detect variation in DNA methylation of mature Chrysanthemum leaves during the floral transition induced by short-day (SD) treatment. Results: For both ea...

Results: For both early- and late-flowering cultivars, the time from the date of planting to the appearance of the capitulum bud and early blooming were significantly shorter than those of the control. The capitulum development of the early-flowering cultivar was significantly accelerated compared to the control, unlike the late-flowering cultivar. The DNA methylation percentage of leaves was significantly altered during flower development. For the early-flowering cultivar, DNA methylation was 42.2-51.3% before the capitulum bud appeared and 30.5-44.5% after. The respective DNA methylation percentages for the late-flowering cultivar were 43.5-56% and 37.2-44.9%. Conclusions: The DNA methylation percentage of Chrysanthemum leaves decreased significantly during floral development.
