Breeding of Japanese Gentians

INQUIRY

Japanese gentian (Gentiana scabra) is native to most of East Asia and is a deciduous perennial herb. Its flowers are beautiful, mostly blue-purple, white, and peach. Research into gentian breeding and cultivation has contributed to the effective breeding of new varieties. In addition, improvements in disease control and cultivation conditions have contributed to the stable production of Japanese gentian.

Lifeasible provides molecular biology techniques developed and effectively used in Japanese gentian breeding. Our solutions play a significant role in helping to develop new varieties of Japanese gentian.

Our breeding platform

• Application of DNA markers in gentian breeding

We offer molecular marker-assisted selection (MAS) technology in Japanese gentian breeding to replace time-consuming field cultivation and bioassays at the seedling development stage. In addition, this technology in gentian breeding enables us to design a rational breeding strategy. We have developed DNA markers associated with several significant agronomic traits in Japanese gentian, including flower color, flower type, and flowering time. We have also developed DNA markers identifying mutations affecting gentian flower color. In addition, we will select flower color phenotypes based on the banding pattern of interlocking molecular markers (DNA).

• Mutagenesis in breeding Japanese gentian

We use mutation breeding techniques, and the introduction of mutations by mutagenesis can expand the available genetic resources of Japanese gentian. Currently, we are using a new mutation breeding technique, i.e., mutagenesis by heavy ion radiation, which can be effectively applied to induce mutations for plant variety improvement. In Japanese gentian breeding, we use heavy ion radiation to induce various mutants in flower color, flower shape, and flowering time. This makes them ideal for gentian breeding, thus providing more choices for consumers and overcoming current cultivation problems.

• Using viral vectors for Japanese gentian research

Plant viral vectors are a vital biotechnological tool in plant research, and the use of viral vectors offers many advantages over other vector systems. For example, viral vectors can be used to express heterologous proteins and induce gene silencing in plant species that are difficult to transform stable. Viral vectors can also accelerate basic research into ornamentals with long growth times. We provide virus-induced gene silencing for different plant species, including some ornamental ones. In gentian, we used an apple latent spherical virus (ALSV) vector infected with FLOWERING LOCUS T (FT) for accelerating flowering in Japanese gentian. In addition, ALSV can reduce generation time and accelerate the breeding process of gentian.
