Understanding the causes of the Sino-Japanese disjunctions in plant taxa has been a central question in eastern Asian biogeography, with vicariance or long-distance dispersal often invoked to explain such patterns. Diabelia Landrein (Caprifoliaceae; Linnaeoideae) comprises four shrubby species with a Sino-Japanese disjunct distribution. The species diversification time within Diabelia, covering a long geological history of the formation process of the Sino-Japanese flora, dated back to the middle Oligocene, therefore, Diabelia would be an ideal model to elucidate the biogeographic patterns of Sino-Japanese disjunctions with climate fluctuation. In this study, we analyzed complete plastome sequence data for 28 individuals representing all four species of Diabelia. These 28 plastomes were found to be highly similar in overall size (156 243-157 578 bp), structure, gene order, and content. Our phylogenomic analysis of the plastomes supported a close relationship between Diabelia ionostachya (Nakai) Landrein & R.L. Barrett var. wenzhouensis (S.L. Zhou ex Landrein) Landrein from eastern China and Diabelia spathulata (Siebold & Zucc.) Landrein var. spathulata from Japan. Diabelia serrata (Siebold & Zucc.) Landrein was identified as sister to a population of Diabelia sanguinea (Makino) Landrein from Tochigi in central Japan and D. spathulata Landrein, from Toyama, central Japan. Most Diabelia lineages were estimated to have differentiated 8-28 Mya. Our results indicate that two independent vicariance events could explain the disjunction between Japan and Korea in the mid to late Miocene, and between Zhejiang and Japan in the early Miocene.

“…While the genus is very distinct, species delimitation within Diabelia is controversial and unclear at present. Traditionally, Diabelia included three species with an unusually disjunct distribution pattern in Japan, East China, and Korea (Liang et al, 2004; Zhou and Wen, 2006; Yang et al, 2011; Shin et al, 2012; see Figure 1). Hara (1983) recognized three species primarily based on the number and length of sepals, with additional varieties and forms recognized on the basis of hair types, nectary shape, fusion of nectaries and corolla, and corolla color.…”

“…Nakai). These two species also have scattered distributions along the southeast coast of East China (e.g., Sihaishan Mts, Wenzhou, Zhejiang; Liang et al, 2004; Zhou and Wen, 2006). The third taxon, D. tetrasepala (Koidz.)…”

“…The small fruits (achenes) of Diabelia are likely to be wind dispersed (Zhou and Wen, 2006) and might be easily blown across the ECS by strong winds associated with typhoons or large storms. The sister lineage of Diabelia is Dipelta , which is endemic to southwest China (e.g., Shaanxi, Gansu, and Yunnan province), and while Diabelia is mainly distributed in Japan, its origin and subsequent dispersal patterns remain uncertain (Wang et al, 2015).…”

Phylogeographic Analysis and Genetic Structure of an Endemic Sino-Japanese Disjunctive Genus Diabelia (Caprifoliaceae)

et al. 2019

The Sino-Japanese Floristic Region (SJFR) is a key area for plant phylogeographical research, due to its very high species diversity and disjunct distributions of a large number of species and genera. At present, the root cause and temporal origin of the discontinuous distribution of many plants in the Sino-Japanese flora are still unclear. Diabelia (Caprifoliaceae; Linnaeoideae) is a genus endemic to Asia, mostly in Japan, but two recent discoveries in China raised questions over the role of the East China Sea (ECS) in these species' disjunctions. Chloroplast DNA sequence data were generated from 402 population samples for two regions ( rpl 32- trn L, and trn H- psb A) and 11 nuclear microsatellite loci were screened for 549 individuals. Haplotype, population-level structure, combined analyses of ecological niche modeling, and reconstruction of ancestral state in phylogenies were also performed. During the Last Glacial Maximum (LGM) period after the Tertiary, Diabelia was potentially widely distributed in southeastern China, the continental shelf of the East China Sea and Japan (excluding Hokkaido). After LGM, all populations in China have disappeared except those in Zhejiang which may represent a Glacial refuge. Populations of Diabelia in Japan have not experienced significant bottleneck effects, and populations have maintained a relatively stable state. The observed discontinuous distribution of Diabelia species between China and Japan are interpreted as the result of relatively ancient divergence. The phylogenetic tree of chloroplast fragments shows the characteristics of multi-origin evolution (except for D. sanguinea ). STRUCTURE analysis of nuclear Simple Sequence Repeat (nSSR) showed that the plants of the Diabelia were divided into five gene pools: D. serrata, D. spathulata, D. sanguinea, D. ionostachya ( D. spathulata var. spathulata -Korea), and populations of D. ionostachya var. ionostachya in Yamagata prefecture, northern Japan. Molecular evidence provides new insights of Diabelia into biogeography, a potential glacial refuge, and population-level genetic structure within species. In the process of species differentiation, ECS acts as a corridor for two-way migration of animals and plants between China and Japan during glacial maxima, providing the possibility of secondary contact for discontinuously distributed species between China and Japan, or as a filter (creating isolation) during glacial minima. The influence of the ECS in speciation and biogeography of Diabelia in the Tertiary remains unresolved in this study. Understanding origins, evolutionary histories, and speciation will provide a framework for the...

“…It had been thought to occur only in the temperate forests of the Japanese Archipelago, with D. serrata from Yakushima Island to the Kanto region of Honshu, D. spathulata from Kyushu to northernmost Honshu and D. tetrasepala from Kyushu to north of Kanto (Hara ). Recently, the new discoveries of D. serrata and D. spathulata were reported by Zhou et al () and Zhou et al () from a coastal area of eastern China (Wenzhou, Zhejiang Province), making the genus Diabelia one of the disjunctively distributed plant genera across the East China Sea. The Sino‐Japanese disjunctive distributions of the two Diabelia species suggest that the genus can be a good model system to explore establishment of plant disjunctions in response to both climate‐induced habitat changes during the late Pleistocene or unpredictable dispersals across the East China Sea in the Holocene.…”

A set of expressed sequence tag (EST) simple sequence repeat (SSR) markers were developed and characterized using next‐generation sequencing technology for the genus Diabelia (Caprifoliaceae). De novo assembly of RNA‐seq reads resulted in 58 669 contigs with the N50 length of 1211 bp. A total of 2746 contigs were identified to harbor SSR motifs, of which 48 primer pairs were designed and 11 were shown to be polymorphic across three morphospecies of Diabelia. When evaluated with 30 individuals, the number of alleles per locus ranged from 2 to 11 and the expected heterozygosity varied from 0.399 to 0.873, respectively. Distance‐based clustering indicated that the EST‐SSR markers can provide sufficient power to distinguish the three species (or populations). These markers will be useful for evaluating the range‐wide genetic diversity of each species and examining genetic divergence and gene flow between the three species.
