Chrysanthemum stunt viroid (CSVd) was inoculated into two chrysanthemum (Chrysanthemum morifolium) cultivars, the CSVd-susceptible cultivar Piato and the CSVd-resistant cultivar Mari Kazaguruma. For CSVd inoculation, grafting and Agrobacterium-mediated inoculation were used. In grafting experiments, CSVd was detectable in Mari Kazaguruma after grafting onto infected Piato, but after removal of ...

The aroma constituents of Chrysanthemum indicum L. were separated by the hydro distillation extraction method using a Clevenger-type apparatus, and were analyzed by gas chromatography-mass spectrometry (GC/MS). The yield of Chrysanthemum indicum L. flower oil was 2.0% (w/w) and the color was light golden yellow. Sixty-three volatile flavor components, which make up 89.28% of the total aroma com...

Chrysanthemum indicum Linné (Asteraceae) is a common Chinese herbal medicine that has been traditionally used for the treatment of inflammation, hypertension and neoplastic diseases in China. However, the mechanism that account for the inhibitory activity of Chrysanthemum indicum Linné against cancer cells is poorly understood. We investigated the effect of Chrysanthemum indicum Linné extracts ...

Chrysanthemums (Chrysanthemum morifolium) are susceptible to tobacco mosaic virus (TMV). TMV-based expression vectors have been used in high-throughput experiments for production of foreign protein in plants and also expressing green fluorescent protein (GFP) to allow visualization of TMV movement. Here, we used TMV expressing the GFP to examine the infection of chrysanthemum by a TMV-based exp...

In this study, inter-simple sequence repeats (ISSRs) and sequence-related amplified polymorphism (SRAP) were applied to assess the genetic diversity in 38 species of Chrysanthemum and related genera. A total of 204 and 567 bands were amplified by 24 ISSR and 25 SRAP primers, of which 196 (97%) and 557 (99%) were polymorphic, respectively. The ISSR-based genetic similarity ranged from 0.016 to 0...
