The beijing municipal institute of park and forest sciences and the beijing forestry university research team have recently published an important product in the field of plant genomics. The study provided a high-quality sequence of the whole genome, with a wide array of red-applied ornamental plants, and provided a basis for the decomposition of such regulatory mechanisms as strains, flowering, growth and development, leading to precision breeding。
A bunch of reds, which belong to the lip-forming rat weeds, and which are colorful, adaptable and easy to cultivate, are widely used in the greening of gardens on a global scale, and are extremely valuable ornamental plants. Since the 1980s, the beijing school of parks and forestry sciences has been conducting systematic research on a series of reds, with some results in the collection, cultivation and selection of their seed resources. More than 10 good species have been selected and promoted, including the super-hot “olympic fire”, the colorful “kyoye” and the bright green “magic” of leaves。
Experts indicated that, as the demand for greening of forests increases, a series of red traditional hybrids are no longer able to meet the demand for quality innovation in terms of plant-based foliage regulation, flowering diversity, color abundance and adaptation to diversity, and that there is a need for more flexible and accurate breeding using genomic editing techniques。
To that end, the scientific team sequenced two single strains of a red “olympian holy fire” and eventually acquired a series of red, high-quality whole genome sequences and explored a series of regulatory mechanisms for red displays of different colours using transcribing group sequencing techniques. At present, researchers are working on the development of new varieties that are resistant and diverse in colour, using a set of existing red resources and their genome information, and are studying regulatory mechanisms for the synthesis of rat weeds, with a view to providing a theoretical basis for the development of reds for more applications。
Sing haebo, a senior engineer at the beijing institute of parks and forest sciences, said that the study would greatly contribute to the development of a new set of red varieties that would accelerate the process from experience to precision breeding, and that a red line of flowers would become richer in the future and more resistant to high temperatures and pests. Through genetic regulation techniques, it is also possible to fine-tune its period。
Since a string of red is an important element in the lip-forming plant, and many varieties of lip-forming plant contain rich aromatics and medicinal components, such as mints for both aromatic and medicinal uses, aromatics and ornamental lavenders, a series of genomics studies will also have important reference value for mechanisms for the formation of lip-forming aromatic and medicinal components and for research and development。
