라. 꿀풀과 속단아재비의 유전적 특성 분석
- 분류학적 재검토시 신종/미기록종의 발굴 가능성이 높은 분류군인 속단아재비의 대한 유전적 특성 분석
- 속단아재비의 엽록체 유전체 크기는 152,128 bp (GC 비율: 38.4%)이며, 유전자는 총 132개로, 87개의 protein coding genes, 37개의 tRNA genes, 8개의 rRNA genes으로 구성되어 있는 것으로 확인

Abstract ▼

The Korean Peninsula which is located at the east of the Eurasian Continent, is connected to the continent to the north and surrounded by water on three sides (NIBR, 2017, 2018a, 2019, 2020, 2021). Therefore, the peninsula-effect is observed in the flora of each region. Although Korea is geographica

The Korean Peninsula which is located at the east of the Eurasian Continent, is connected to the continent to the north and surrounded by water on three sides (NIBR, 2017, 2018a, 2019, 2020, 2021). Therefore, the peninsula-effect is observed in the flora of each region. Although Korea is geographically a peninsula which is known to have low diversity, plant diversity per unit area is relatively high and the distribution areas are very complicated (NIBR, 2017, 2018a, 2019, 2020, 2021).

This research was carried out to illuminate floristic data of unexplored habitats by performing natural field investigation from February to November in 2022. The present study provides a list of endemic plants species, endangered species, exotic species as well as floristic list for management and conservation of biodiversity of investigated areas. The results obtained were as follows. As for the discovery of three new species, eleven unrecorded taxa found during the course of unexplored habitats in Korea.

As results of a southwestern coast area (Wando-gun and four other regions) surveys, we have discovered a total of 195 taxa; 70 families, 142 genera, 392 species, 14 varieties, and 2 forms. The red data of vascular plants according to the IUCN criteria were examined one taxa. The floristic regional indicator plants found in this area were 46 taxa comprising two taxa of degree Ⅴ, four taxa of degree Ⅳ, 40 taxa of degree Ⅲ. The Korean endemic plants were 13 taxa. The alien plants were identified as 46 taxa

We used a genetic approach to identify the taxonomic characteristics of Korean Paraphlomis koreana. Our results revealed that Paraphlomis koreana, considered endemic to the Korean Peninsula, is the most closely related to Matsumurella chinensis. In addition, the genetic variation was not enough to be considered as an different species. Therefore, we suggest that the taxonomic position of P. koreana should be reconsidered.
