“…In the present study, about 85% of tea accessions were collected from Boseong and Suncheon in Jeollanam-do (JN) ( Table 2). According to Eom and Kim, the tea seeds obtained from China were firstly cultivated in Mount Jiri in JN and so a majority of tea plants are included in the Honam region (Jeollanam-do and Jeollabuk-do) [35]. In addition, tea experiment stations in Boseong experiment station (BES) and Mokpo experiment station (MES, a city close to Suncheon) have collected the tea accessions since the late 1990s [18].…”

Tea (Camellia sinensis (L.) O. Kuntze) is cultivated in many developing Asian, African, and South American countries, and is the most widely consumed beverage in the world. It is of critical importance to understand the genetic diversity and population structure of tea germplasm for effective collection, conservation, and utilization. In this study, 410 tea accessions collected from South Korea were analyzed using 21 simple sequence repeat (SSR) markers. Among 410 tea accessions, 85.4% (350 accessions) were collected from Jeollanam-do. A total of 286 alleles were observed, and the genetic diversity and evenness were estimated to be on average 0.79 and 0.61, respectively, across all the tested samples. Using discriminant analysis of principal components, four clusters were detected in 410 tea accessions. Among them, cluster 1 showed a higher frequency of rare alleles (less than 1%). Using the calculation of the index of association and rbaD value, each cluster showed a clonal mode of reproduction. The result of analysis of molecular variance (AMOVA) showed that most of the variation observed was within populations (99%) rather than among populations (1%). The present study revealed the presence of lower diversity and simpler population structure in Korean tea germplasms. Consequently, more attention should be focused on collecting and conserving the new tea individuals to broaden genetic variation of new cultivars in future breeding of the tea plant.

“…H. japonicus is native to Japan, Korea, and eastern China (Zhou and Bartholomew 2003), the Russian Far East (Maximovich 1859), and Vietnam and Laos (Pé telot 1954). Phytosociological and field studies report H. japonicus in communities dominated by trees-specifically Alnus (Lee et al 1976, Jeong et al 2012, Lee et al 2013, Salix (Kolbek and Karolí mek 2008, Oh et al 2010, Jeong et al 2012, Lee et al 2013, Quercus (Lee et al 1976, Kolbek and Karolí mek 2008, Oh et al 2010, Robinia (Lee et al 1976, Kolbek and Karolí mek 2008, Jeong et al 2012, Lee et al 2013 and Ahn 2014), and Camellia (Kim et al 2010, Lee et al 1976, Lee and Ahn 2014, Eom and Kim 2017).…”

Biogeographers assign the center of origin of Cannabis to "Central Asia," mostly based on wildtype plant distribution data. We sought greater precision by adding new data: 155 fossil pollen studies (FPSs) in Asia. Many FPSs assign pollen of Cannabis or Humulus (C-H) to collective names (e.g., Cannabis/Humulus or Cannabaceae). To dissect these aggregate data, we used ecological proxies. C-H pollen in a steppe assemblage (with Poaceae, Artemisia, Chenopodiaceae) was identified as wild-type Cannabis. C-H pollen in a forest assemblage (Alnus, Salix, Quercus, Betula, Robinia, Juglans) was identified as Humulus. C-H pollen curves that upsurged alongside crop pollen were identified as cultivated hemp. Subfossil seeds (achenes) at archaeological sites also served as evidence of cultivation. FPSs and archaeological sites were mapped using geographic information system (GIS) software. The oldest C-H pollen consistent with C. sativa dated to 19.6 million years ago (mya), in northwestern China. However, Cannabis and Humulus diverged 27.8 mya, based on molecular clock analysis. We bridged the temporal gap between the divergence date and the oldest pollen by mapping the earliest appearance of Artemisia. These data converge on the northeastern Tibetan Plateau, which we deduce as the C. sativa center of origin. This co-localizes with the first steppe community that evolved in Asia. From there, Cannabis first dispersed west (Europe by 6 mya) then east (eastern China by 1.2 mya). Cannabis pollen in South Asia appeared by 32.6 kya. The earliest Cannabis seeds were found in Japan, 10,000 BCE, followed by China.
