Natural interploidy hybridization among the key taxa involved in the origin of horticultural chrysanthemums

Abstract: Understanding hybridization and introgression between natural plant populations can give important insights into the origins of cultivated species. Recent studies suggest differences in ploidy may not create such strong reproductive barriers as once thought, and thus studies into cultivated origins should examine all co-occurring taxa, including those with contrasting ploidy levels. Here, we characterized hybridization between Chrysanthemum indicum, Chrysanthemum vestitum and Chrysanthemum vestitum var. latifolium, the most important wild species involved in the origins of cultivated chrysanthemums. We analysed population structure of 317 Chrysanthemum accessions based on 13 microsatellite markers and sequenced chloroplast trnL-trnF for a subset of 103 Chrysanthemum accessions. We identified three distinct genetic clusters, corresponding to the three taxa. We detected 20 hybrids between species of different ploidy levels, of which 19 were between C. indicum (4x) and C. vestitum (6x) and one was between C. indicum and C. vestitum var. latifolium (6x). Fourteen hybrids between C. indicum and C. vestitum were from one of the five study sites. Chrysanthemum vestitum and C. vestitum var. latifolium share only one chloroplast haplotype. The substantially different number of hybrids between hybridizing species was likely due to different levels of reproductive isolation coupled with environmental selection against hybrids. In addition, human activities may play a role in the different patterns of hybridization among populations.

Composition and production method of pulmonary tuberculosis therapeutics development from chrysanthemum indicum l. extract

Abstract: PURPOSE: An anti-tuberculosis composition is provided to be used as a therapeutic agent for treating multidrug resistant tuberculosis and to shorten period for developing a novel drug. CONSTITUTION: An anti-tuberculosis composition contains a Chrysanthemum indicum L. extract as an active ingredient. A method for manufacturing the composition comprises: a step of preparing Chrysanthemum indicum L.; a step of putting Chrysanthemum indicum L. and a solvent in a container; a step of heating the container and extracting Chrysanthemum indicum L.; a step of filtering, concentrating, and drying the extract and making the extract into powder; and a step of dispersing the powder using distilled water, removing fat from the dispersed liquid, and fractioning with a solvent. The solvent is water or a mixture of water and alcohol.

Comparative transcriptome analysis of three chrysanthemums provides insights into flavonoid and terpenoid biosynthesis

Abstract: Chrysanthemum indicum var. aromaticum is an important resource plant for breeding excellent aromatic varieties of ornamental and medicinal chrysanthemums. However, the biosynthesis and regulation mechanisms of typically aromatic ingredients in C. indicum var. aromaticum are poorly understood, which restricted the utilization of this plant. Here, the transcriptome of C. indicum var. aromaticum was investigated and comparative analysis was conducted with the other two closely related chrysanthemum taxa C. indicum and C. nankingense. The global transcriptome profiles showed clear difference of gene expression patterns between the three chrysanthemums, of which 52 flavonoid biosynthesis-associated genes, 157 transcription factors, and 24 flavonoid Uridine diphosphate (UDP) -glucuronosyl and -glucosyltransferase genes were significantly differentially expressed. Furthermore, 22 differential expression genes (DEGs) in relation to the terpenoid backbone biosynthesis and 183 DEGs related to terpenoid diversification were identified. Of which, 14 genes involved into TS/CYP gene cluster showed higher expression in CIA than those in CI or CN. These results increased our understanding of flavonoid diversification and aromatic ingredients accumulation in plants, and will also help improve resource conservation and sustainable utilization of the important resource plant C. indicum var. aromaticum.

Studies on tomato aspermy virus from Chrysanthemum indicum L. in New Zealand

Abstract: Tomato aspermy virus was found in chrysanthemum in New Zealand for the first time, in commercial gardens in Christchurch, Wanganui, and Auckland. The virus was transferred experimentally to marigold, nasturtium, aster, capsicum, chrysanthemum, tamarillo, lettuce, tomato, Nicotiana glutinosa L., Chenopodium amaranticolor Coste & Reyn., tobacco, black nightshade. New Zealand spinach, and zinnia. The longevity of the virus was between 7 and 11 days and the thermal inactivation point between 65° and 70°c. The dilution end point of the virus was between 1–50 000 and 1–100 000. The virus was transmitted by the green peach aphid.
