In this study, the dyeing of Chrysanthemum indicum Linne alone and the combined dyeing of Chrysanthemum indicum Linne and onion shell were first performed to compare dyeing properties. A combination extract of Chrysanthemum indicum Linne and onion shell can be expected to improve coloration. A Hanbok design for children used a natural dyeing fashion dyeing method to make the Chrysanthemum pattern. Chrysanthemum indicum Linne is a type of wild chrysanthemum with various medicinal effects for headache and stress relief, skin diseases, insomnia and depression. Widely used onion shells have medicinal properties that help prevent and treat various adult diseases. The colors of silk dyed exclusively by Chrysanthemum indicum Linne, and the colors of silk dyed by Chrysanthemum indicum Linne and onion shell extract are yellow; in addition, silk dyed by Chrysanthemum indicum Linne and onion shell extracts were almost all unchanged. Four hanboks, which are comfortable for children to wear and use, were produced using Chrysanthemum indicum Linne and onion shell extracts. If children wear hanbok fashion products with auspicious patterns, they can provide a chance to simultaneously experience the traditional symbolism of Korean patterns and culture. In addition, it is expected to develop pride in traditional dress culture.

Chrysanthemum chlorotic mottle viroid(CChMVd) isolates have been identified from chrysanthemum showing yellow spots or infected without symptom. They were 399-400 nucleotides length of RNA. CChMVd-SSHA6(GenBank accession no. DQ450682) revealed a GAAA to DUUC substitution in positions 82-85 of CChMVd-MSIN34(GenBank accession no. DQ402041). In vitro RNA transcripts with the complete CChMVd sequence were infectious and induced the typical CChMVd infection symptom of yellow spots in chrysanthemum cv. Sharotte. CChMVd caused reduction in growth in some cultivars, whereas some cultivars were not affected. This is the first report on the occurrence of CChMVd in chrysanthemum in Korea.

Since whole-genome duplication (WGD) of diploid Chrysanthemum nankingense and de novo assembly whole-genome of C. seticuspe have been obtained, they have afforded to perceive the diversity evolution and gene discovery in the improved investigation of chrysanthemum breeding. The robust tools of high-throughput identification and analysis of gene function and expression produce their vast importance in chrysanthemum genomics. However, the gigantic genome size and heterozygosity are also mentioned as the major obstacles preventing the chrysanthemum breeding practices and functional genomics analysis. Nonetheless, some of technological contemporaries provide scientific efficient and promising solutions to diminish the drawbacks and investigate the high proficient methods for generous phenotyping data obtaining and system progress in future perspectives. This review provides valuable strategies for a broad overview about the high-throughput identification, and molecular analysis of gene function and expression in chrysanthemum. We also contribute the efficient proposition about specific protocols for considering chrysanthemum genes. In further perspective, the proper high-throughput identification will continue to advance rapidly and advertise the next generation in chrysanthemum breeding.

The presence of Chrysanthemum stunt viroid (CSVd) in seed and pollen of diseased chrysanthemum was demonstrated. In seeds infected male parent from crosses in May, CSVd was transmitted to 6.7% of the progeny seedlings, whereas if the female parent was infected, CSVd transmission rate was between 46.9 and 75.7%. A relatively high incidence of 94.4 to 96.0% seed transmission occurred when both parents were infected. In seeds infected male parent from crosses in December, no progeny seedlings were infected with CSVd, whereas if the female parent did, CSVd transmission rate was 1.5%. When both parents were infected, 6.9% seed transmission was occurred. The seed transmission rate depended on the temperature when the crosses were made. CSVd was not detected in the non-infected female parent pollinated with infected pollen but was transmitted to the progenies. This is the first report of seed-borne transmission of CSVd in chrysanthemum.

In an acute toxicity test for Chrysanthemum indicum Linne, 0.5~10 g/kg of Chrysanthemum indicum Linne extracts were administered. Chrysanthemum indicum Linne did not produce acute toxicity even at high doses of 10 g/kg, making it a highly safe material. In the chronic toxicity test, oral administration of Chrysanthemum indicum Linne up to 2 g/kg was carried out for 13 weeks, showing liver non-toxicity. The gout inhibitory effect of Chrysanthemum indicum Linne extracts was measured by inflammatory cytokine expression and foot thickness after 24 h of monosodium urate crystal (MSU) oral administration when inflammatory cytokine production reached a maximum. The group administered 2~4 g/kg of Chrysanthemum indicum Linne extract showed an inhibitory effect on gout inflammation and edema, whereas the 10 g/kg administered group showed an increase in inflammation. Therefore, the moderate concentration of Chrysanthemum indicum Linne extract for gout inhibitory effect was under 4 g/kg. Chrysanthemum indicum Linne extract showed an anti-inflammatory effect on MSU as a relatively safe material at high capacity. These results indicate that Chrysanthemum indicum Linne extract is thought to be an excellent substance for gout prevention.

Chrysanthemum stunt viroid (CSVd), a noncoding infectious RNA molecule, causes seriously economic losses of chrysanthemum for 3 or 4 years after its first infection. Monomeric cDNA clones of CSVd isolate SK1 (CSVd-SK1) were constructed in the plasmids pGEM-T easy vector and pUC19 vector. Linear positive-sense transcripts synthesized in vitro from the full-length monomeric cDNA clones of CSVd-SK1 could infect systemically tomato seedlings and chrysanthemum plants, suggesting that the linear CSVd RNA transcribed from the cDNA clones could be replicated as efficiently as circular CSVd in host species. However, direct inoculation of plasmid cDNA clones containing full-length monomeric cDNA of CSVd-SK1 failed to infect tomato and chrysanthemum and linear negative-sense transcripts from the plasmid DNAs were not infectious in the two plant species. The cDNA sequences of progeny viroid in systemically infected tomato and chrysanthemum showed a few substitutions at a specific nucleotide position, but there were no deletions and insertions in the sequences of the CSVd progeny from tomato and chrysanthemum plants.

Tomato spotted wilt virus (TSWV) has been identified in commercial chrysanthemum cultivars in Korea. Nucleotide sequences of the N gene of TSWV-ch14 isolated from infected chrysanthemum were determined and deposited in GenBank under accession no. DQ453158. The symptoms consisted of dark colored leaf necrosis, black streaks along the stem, wilting of plant parts in 'Sinma'; and chlorotic spots, necrosis of axillary shoots and withering of leaves in 'Hwarang'. Electron micrographs of leaf preparation of Nicotiana rustica infected with TSWV-ch14 contained spherical particles around 85 nm in diameter. TSWV was identified from chrysanthemum by sequence determination of N nucleocapsid protein and virion observation by transmission electron microscope. This is the first reported observation on TSWV in chrysanthemum in Korea.

Infection rate of Chrysanthemum stunt viroid (CSVd) in 64 commercial chrysanthemum cultivars cultivated in Korea ranged from 9.7 to 66.8$\%$. Symptoms on leaves of CSVd-infected chrysanthemum included yellow spots, chlorosis, vein clearing, vein bending and crumpling. CSVd induced flower malformation in 'Scot', color change in 'Sharotte', and color breaking in 'Sharon'. CSVd caused reduction of plant height, leaf size, flower size and the flowers number by $32-50\%,\;26-35\%$, $14-36\%\;and\;14-75\%$, respectively. In conclusion, CSVd affected plant height, leaf size and flower quality in chrysanthemum plants.

Some functional properties and nutritive value were determined for the protein concentrated fractionated from chrysanthemum flower in orer to renew interest in the flowers as food. Proximate components of chrysanthemum flower protein concentration (FPC) showed 61.2% protein, 2.0% fat and 35.2% carbhydrate on a dry basis. In amino acid composition of FPC, glutamic acid was the highest in the content, follwoed by aspartic acid, leucine and lysine. The ratio of essential/ total amino acids(E/T) was 0.42, showing a higher level of essential amino acids compared to the FAO reference protein. Digestibility of chrysanthemum FPC by pepsin and trypsin was lwoer than that of casein and was negatively correlative to both water and fat absorptions. Similar characteristics were determined between chrysanthemum FPC and milk casein in their emulsifying activity and emulsion stability. This results indicate that flowers or petals of chrysanthemum might be developed as a good source of protein.
