Program 6. Forestry income increase and utilizing industrialization by using forest bioresources
The National Institute of Forest Sciences establishes the bases for collection, evaluation, and conservation of resources, securing original technology for medicinal and daily life materials, developing technologies for cultivation and management of resources. This allows us to build an industrial materialization platform for forest bioresources, discovering its functionality and creating a new variety of resources, cultivating, distributing and processing a post-harvest.

□ Major outcomes
6-1 Research on the establishment for application of bio-information
·Transformation-based genome editing technology for forest trees was developed in the agenda 'Research on the bioinformatical application for forest bioresources' through the subproject 'Establishment of CRISPR/Cas9-mediated genome editing in forest trees', and the hybrid poplars reduced lignin content were generated. Our results demonstrate that genome editing technology can improve production of lignocellulosic biomass as feedstock for biosaterials. To overcome regulatory restrictions for GMOs and enhance the performance, it is important to develop transgene-free genome editing protocol.
·"Development of virus-free plants production technology of major forest income resources" induces cultivation of superior clone propagation, income increase, and reduces production cost by verifying virus-free plants, and Rubus coreanus (Korean rasberry) tissue culture plants require future proliferation and on-site verification.
·The 'Holobiome Information-Based Study on the Development of Functional Microbe Materials for Pine Mushrooms and Gastrodia elata Blume's Productivity' has yielded useful results on the discovery of functional microorganisms and plant-microbe interactions, and a phased study is needed to investigate the empirical effects.
·‘The Genetic information construction of Forest Bioresources and Development of Biological fingerprint analysis technology’ developed species identification analysis and applied to establish scientific forestry management stratedgy in seed harvest stand in Larix gmelinii var. olgensis. It constructed biological fingerprint information for identification of conifer timber species. This information can support for Regulation To Promote Legal Timber Trade. Henceforward, We shall construction of biological fingerprint information to identify species of broad-leaved tree in abroad.

6-2 Research on identification of medicinal resources and application technologies
·Research on the exploration of anti-inflammatory substances and pharmacological mechanisms of the Korean Rhamnaceae requires study on industrial technology transfer and practical use of the original technology derived from research results.
·Research on the Breeding of Korean angelica and the establishment of standard cultivation techniques for medicinal herbs needs to promote specific cultivation and breeding techniques that can directly affect an increase in income for foresters who grow medicinal herbs.
·The research on the effect of improving bone metabolism in Poria cocos requires a research strategy for the practical use of industrialised raw materials through an exploratory study on the effect of improving bone metabolism on strains with excellent production. Research on plant oil refining to improve respiratory diseases needs to promote studies such as ease of supply of raw materials, extraction costs, and duration of oil refining activities in order to industrialize materials.
·A research on the standardization of the pharmacological efficacy-based quality of wild-simulated ginseng requires a study on the reproducibility of the technology of root age using transcriptome and country of origin using metabolome.
·Research on natural materials of forest medicinal resources needs to actively utilise forest policy support for research outcomes, and it is also necessary to focus research on herbal and medicinal products and seek ways to find out early performance.

6-3 Research on discovery and application of functional lifecare materials
·The Mugunghwa research project needs to be focused on improving the ornamental function in the follow-up project.
·Means for development in the Hanji research field should be established by using the results on the research of Hanji and the source tree specices.
·It is necessary to carry out an industrialisation-based study through this research and the development of a follow-up study for skin regeneration via evergreen oak trees.
·For the development of hair health-care materials, lead tree species should be selected in consideration of the ease of supply of raw materials.
·Research on the production of fine mulberry trees and the mechanisation process of high-quality hanji suggests the target level achieved through research and needs to be supplemented in the evaluation of hanji characteristics.
·The development of evergreen broadleaf for pet-care materials needs to be content-oriented to specify the title of it, and to set specific KPIs according to annual research performance and it also needs to be supplemented with strategies.

6-4. Cultivation of forest income resources and development of management technology
·Through research on post-harvest loss reduction technology development of forest products and commercialization research, the optimal storage temperature and distribution period of hardy kiwifruit (Actinidia arguta) were identified, and the quality of storage and distribution of wild vegetables was improved through micro oil sprayed thermal air technique. We plan to publish the post-harvest manuals through field applicability evaluations in the future.
·Research on discover major sources of honey trees and use them for multiple purposes is discovering trees with high production of honey and developing various way to utilize honey resources. The empirical research on establishing a honey plant complex in response to climate change develops various complex models that can increase rental income, and establishes a supply system for excellent seedlings of honey trees.
·In order to satisfy the upcoming demand for new landscape trees as a material of urban forest and green-teriors, the tree form and flower characteristics of superior individuals in Prunus spp., dogwood and golden-rain trees were investigated and new genetic resources were collected. The effect of smart irrigation system that maintains the soil water content as 15% in the container were analyzed. It was found that sap flow, irrigation efficiency and tree growth were more excellent in smart irrigation system than the conventional semi-automatic irrigation.
