BACKGROUND Simple sequence repeats (SSRs) are ubiquitous in eukaryotic genomes. Chrysanthemum is one of the largest genera in the Asteraceae family. Only few Chrysanthemum expressed sequence tag (EST) sequences have been acquired to date, so the number of available EST-SSR markers is very low. METHODOLOGY/PRINCIPAL FINDINGS Illumina paired-end sequencing technology produced over 53 million se...

Salt stress has some remarkable influence on chrysanthemum growth and productivity. To understand the molecular mechanisms associated with salt stress and identify genes of potential importance in cultivated chrysanthemum, we carried out transcriptome sequencing of chrysanthemum. Two cDNA libraries were generated from the control and salt-treated samples (Sample_0510_control and Sample_0510_tre...

High temperature stress causes damages to chrysanthemum by adversely affecting its growth and development. To identify differentially expressed proteins under heat stress, heat-tolerant variety (Chrysanthemum nankingense ) and heat-susceptible variety (Chrysanthemum ‘Wanfen’) were selected to contrast the full leaf proteome profiles with or without 6 h of heat stress (40°C), a parameter establi...

The aim of the present study was to optimize flavonoid extraction from Chrysanthemum morifolium and to study the antitumor effects of flavonoids on human gastric cancer MKN45 cells in vitro. A single factor experiment was designed and the extraction process was optimized using an orthogonal test. MKN45 cells were treated with different concentrations of flavonoid from Chrysanthemum morifolium f...

An apparent physiological disease, Yellow Strapleaf (YSL) of Chrysanthemum morifolium Ram., was described by Jackson and Woltz (1) in 1959. The disease has been observed in Florida plantings during the last 6 years and has been noted in Massachusetts 3. Symptoms include chlorosis of new growth, green netting of leaves, and narrow strapshaped leaves that hook at the distal ends (fig 1A). The con...

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...
