“…The effects were similar to the effects of the rolC gene under CaMV 35S promoter (Mitiouchkina and Dolgov, 2000). The purpose in this study was the production of rolC-transformed chrysanthemum with a bush phenotype but normal size flowers.…”

“…But, this was not achieved as the chrysanthemums transformed with rolC under rolC native promoter had smaller size flower. Malformed leaves and flowers by introduction of the rolC gene under CaMV 35S promoter have been reported in chrysanthemum (Mitiouchkina and Dolgov, 2000), but these malformations were not detected in the chrysanthemum transformed with rolC under rolC native promoter. This promoter difference seems to have been involved in the different morphological changes.…”

“…Chrysanthemums, transformed with rolC which has the dwarfed, bush habit, have already been produced by Mitiouchkina and Dolgov (2000), but, these plants also had smaller flowers. The rolC gene introduced in their study was driven by CaMV 35S promoter, which was effective throughout the plant.…”

The effects of rolC on morphogenesis of Chrysanthemum morifolium Ramat. 'Ogura-nishiki' were studied. The ray flowerets in the rolC-transformed plants were shorter than those in wild-type plants, but the transformation enhanced outgrowth of lateral shoots and reduced internode elongation. Studies on adventitious shoot and root formation from leaf segments revealed that the rolC transgene led to reduced root formation but enhanced adventitious bud formation. This enhanced cytokinin-like activity was consistent with phenotypes observed in the rolC-transformed plants.

“…They obtained five transgenic 'Jinba' plants using A. tumefaciens C58C1 carrying antisense Ls cDNA which showed decreased axillary branching, although this was strongly dependent on the season (highest percentage of viable axillary buds when planted in April, followed by planting in August and then June), and changes in floral structure were also shown by selected transformants. Insertion of 35S-rolC gene of Agrobacterium rhizogenes in Chrysanthemum morifolium led to the induction of dwarfism in chrysanthemum plants with altered plant morphology 43 . Susceptibility to viral, fungal and bacterial diseases is the main constraint that several researchers have tried to combat through transgenic approaches.…”

Development of transgenics is the need of the modern era of plant breeding, as they possess the potential to incorporate those characters in crop varieties which are either difficult or impossible through conventional breeding approaches. In case of ornamental crops, the progress made in transgenic breeding is not that impressive like in cereals, pulses and vegetables, but the initiatives taken and advancements made have implicated the bright future of this technology in ornamental crops. Improved morphology, flower colour, resistance and fragrance are some of the desired novel traits in ornamental crops where transgenic approaches need to intervene. Transgenic breeding in major cut-flower crops like rose, chrysanthemum, gladiolus and carnation has provided avenues for incorporation of novel traits in other ornamental crops as well and has made such crops an ideal target for application of other advanced technologies.

To set efficient transformation system in chrysanthemum, thirty-four chrysanthemum (Dendranthema grandiflorum Kitamura) varieties were collected and cultured for shoot regeneration. Five varieties, 'Shuho-no-chikara', 'Zinba', 'Baekma', 'Pink pride' and 'Keumsu' of them were selected, because they had a high shoot regeneration efficiency. MS medium containing 1.0 mg/L NAA and BA respectively was very adequate for shoot regeneration in those varieties. MS medium with 3.0 mg/L NAA and 1.0 mg/L kinetin in 'Shuho-no-chikara' and the medium with 0.5 mg/L NAA and 3.0 mg/L BA in 'Keumsu' were also suitable for shoot regeneration. The most efficient callus induction and shoot regeneration were obtained on MS medium. Shoot regeneration was enhanced more than 8% on MS medium with 0.3% phytagel and 10-15 mg/L putrescine. The best cultural material for shoot regeneration was stem. When stem was used as a culture material, shoot regeneration rate was increased more than 26% and the days to shoot regeneration was shortened about 14 days. 서 론국화 (Dendranthema grandiflorum Kitamura)는 국내에서 절화류 중 재배면적 및 생산액이 1~2위를 기록하고 있는 중요 화훼작물이며, 세계적으로도 소비량이 2위인 절화
