Article Synopsis
  • - A comprehensive DNA barcode reference library has been created for Japanese native woody seed plants, covering 834 species from 43 orders and 99 families, which represents a substantial portion of Japan's native flora.
  • - The library includes 6,216 plant specimens collected from various biomes in Japan, utilizing three chloroplast DNA regions (rbcL, trnH-psbA, matK) to generate 14,403 barcode sequences.
  • - Identification rates for species are significantly higher when combining multiple DNA regions, with rates reaching up to 98.6% for species and 100% for genus, showcasing the library’s effectiveness for research and as a model for future flora studies in Japan.

is a species of Prunus native to eastern Asia. We determined the first complete chloroplast genome of using genome skimming approach. The cp genome was 157,905 bp long, with a large single-copy region (LSC) of 85,910 bp and a small single-copy region (SSC) of 19,123 bp separated by a pair of inverted repeats (IRs) of 26,436 bp.

is a flowering tree species with high ornamental and economic values. We determined the first complete chloroplast genome of using genome skimming approach. The cp genome was 157,813 bp long, with a large single-copy region (LSC) of 85,931 bp and a small single-copy region (SSC) of 19,120 bp separated by a pair of inverted repeats (IRs) of 26,381 bp.

is a recently described wild cherry species from the Kii Peninsula, Japan. Here we determined the first complete chloroplast genome of using genome skimming approach. The cp genome was 157,898 bp long, with a large single-copy region (LSC) of 85,926 bp and a small single-copy region (SSC) of 19,070 bp separated by a pair of inverted repeats (IRs) of 26,451 bp.

Article Synopsis
  • Understanding phenological events, like flowering times, is crucial for predicting how species will react to climate change, particularly in cherry trees in Japan.
  • A study analyzed a 29-year data set on flowering times across different cherry tree species, discovering that while responses to chill were similar among species, earlier flowering trees were more affected by heat.
  • Projections indicate all cherry tree species could bloom about 30 days earlier by 2100, which could significantly impact cultural festivals in Japan and provide insights into broader ecological effects.

Numerous cultivars of Japanese flowering cherry (Prunus subgenus Cerasus) are recognized, but in many cases they are difficult to distinguish morphologically. Therefore, we evaluated the clonal status of 215 designated cultivars using 17 SSR markers. More than half the cultivars were morphologically distinct and had unique genotypes.

Many indicators/indices provide information on whether the 2010 biodiversity target of reducing declines in biodiversity have been achieved. The strengths and limitations of the various measures used to assess the success of such measures are now being discussed. Biodiversity dynamics are often evaluated by a single biological population metric, such as the abundance of each species.

The genetic resources of a particular species of flowering cherry, Cerasus jamasakura, have high conservation priority because of its cultural, ecological and economic value in Japan. Therefore, the genetic structures of 12 natural populations of C. jamasakura were assessed using ten nuclear SSR loci.

Climate change is affecting plant phenology worldwide. Phenological responses vary among species, but it is not clear how responses differ among closely related species. We examined a 25-yr record (1981-2005) of flowering times for 97 trees, representing 17 species and hybrids of cherry (Cerasus sp.
