RESUMO
Two new species of Peucedanum (Apiaceae), P.miroense and P.tongkangense, from Gangwon Province, South Korea, are described. Both species are most similar to P.elegans and P.hakuunense because of their linear ultimate leaf segments. Peucedanummiroense was found on crevices of rocks in mountain summits and can be distinguished by its pubescent ovary, purple anthers, oblong schizocarp, and 1 or (2) vittae per vallecula and 4 on the commissural face. Peucedanumtongkangense was found in open areas on rocky cliffs along the Donggang River and can be distinguished by its glabrous ovary, whitish-yellow anthers, narrowly ellipsoid schizocarp, and 3 vittae per vallecula and 4 on the commissural face. Distinguishing characteristics, full descriptions, illustrations, photographs, taxonomic notes on geographical distribution, ecology, and phenology of the two species are presented. An identification key for all Korean species of Peucedanum is also provided. In addition, the mericarp surface of two new species and their close relatives are compared using micromorphological analysis.
RESUMO
Aruncus dioicus var. kamtschaticus is an economically important herb in the cold temperate regions of East Asia, and displays highly variable morphological features. Completed chloroplast genome of A. dioicus var. kamtschaticus isolated in Korea is 157,859 bp long with four subregions: 85,972 bp of large single copy and 19,185 bp of small single-copy regions separated by 26,351 bp of inverted repeat regions. The genome includes 131 genes (86 protein-coding genes, eight rRNAs, and 37 tRNAs). Phylogenetic analyses show that our chloroplast genome was clustered with two partial chloroplast genomes of A. dioicus.
RESUMO
Completed chloroplast genome of Campanula takesimana Nakai isolated from Dokdo island in Korea is 169,719 bp long (GC ratio is 38.8%) and has four subregions: 102,381 bp of large single-copy (37.8%) and 7,750 bp of small single-copy (32.6%) regions are separated by 29,794 bp of inverted repeat (41.3%) regions including 131 genes (87 protein-coding genes, eight rRNAs, and 36 tRNAs). Phylogenetic analyses suggested that C. takesimana from Dokdo Island form a clade with C. takesimana from Ulleungdo Island and that chloroplast genomes of the two accessions are diverged.
RESUMO
Goodyera schlechtendaliana is a common orchid species in East Asia, providing a case to study phylogeographic structure of understory plants in warm temperate forests. Here, we present the complete chloroplast genome of the Korean G. schlechtendaliana. Its length is 153,801 bp and it has four subregions; 82,683 bp of large-single-copy and 18,048 bp of small-single-copy regions are separated by 26,535 bp of inverted repeat regions, including 133 genes (86 protein-coding genes, eight rRNAs, and 39 tRNAs). Phylogenetic analyses suggest that the chloroplast genomic data should be useful in future phylogeographic and phylogenetic studies of Goodyera.
RESUMO
While symbiotic fungi play a key role in the growth of endangered Calanthe orchid species, the relationship between fungal diversity and Calanthe species remains unclear. Here, we surveyed root associated fungal diversity of six Calanthe orchid species by sequencing the internal transcribed spacer (ITS) region using 454 pyrosequencing. Our results revealed that Paraboeremia and Coprinopsis are dominant fungal genera among Calanthe species. In terms of overall relative abundance, Paraboeremia was the most common fungal genus associated with Calanthe roots, followed by Coprinopsis. Overall fungal diversity showed a significant degree of variation depending on both location and Calanthe species. In terms of number of different fungal genera detected within Calanthe species, C. discolor had the most diverse fungal community, with 10 fungal genera detected. This study will contribute toward a better understanding of those fungi that are required for successful cultivation and conservation of Korean Calanthe species.
