Breeding of Chrysanthemums
INQUIRYIntroductions
There are wide varieties of chrysanthemums, which are usually propagated by cuttings, division, grafting, and tissue culture. However, the gene pool of chrysanthemums lacks certain characteristic genes, such as the blue gene and early flowering gene, which limits its conventional breeding process. With the development of molecular biology, improved flowers' breeding through genetic engineering has also been rapidly developed. Currently, the breeding objectives of chrysanthemums are to change flower color, alter plant morphology, extend the flowering period, and breed varieties resistant to pests, diseases, and abiotic stresses.
Lifeasible is dedicated to inserting exogenous genes into chrysanthemums through transgenic technology to improve targeted traits and achieve breeding goals for chrysanthemums in terms of flower color, duration, and resistance.
What We Follow
The development of molecular marker technology and multi-omics technology has accelerated the breeding process. We are able to identify candidate genes for important traits in chrysanthemums through the integration of multi-omics data and then use gene editing techniques such as CRISPR / Cas9, zinc finger nucleases, or transcription activator-like effector nucleases to support the improvement of horticultural traits in chrysanthemums.

What We Provide
Flower Color Improvement
The mechanism of chrysanthemum petal coloration and the relationship between flower color and pigmentation have been elucidated. Due to the lack of flavonoid 3',5'-hydroxylase genes, there are no purple or blue varieties of chrysanthemums. We are able to achieve successful transformation of the flavonoid 3',5'-hydroxylase gene through transgenic technology. We are working to investigate the mechanism of flower color chimera formation and expect to produce chrysanthemum varieties with chimeric flower colors.
Flowering Time Improvement
The flowering time of chrysanthemums is influenced by a combination of photoperiod and temperature. We are able to apply transgenic technology to regulate the flowering time of chrysanthemums. Genes related to flowering time are transferred into chrysanthemums to induce early flowering. We are able to insert mutated ethylene receptor genes into chrysanthemum varieties to reduce the sensitivity of transgenic plants to ethylene and extend the flowering time of chrysanthemums.
Disease Resistance Improvement
Diseases of chrysanthemums are mainly divided into viruses and virus-like diseases. Infected chrysanthemum plants are dwarfed and withered, and leaf spot and plant growth are inhibited, which seriously affects the ornamental value of chrysanthemums. We are able to select resistant plants by introducing some fragments of the virus or virus-like genes that inhibit the occurrence of viruses in chrysanthemums.
Salt Tolerance Improvement
The lack of freshwater resources makes the breeding of salt-tolerant varieties a priority. We are able to construct transgenic plants overexpressing genes associated with resistance to salt stress to screen for salt-tolerant chrysanthemum varieties.
