Although fundamental to the study of invasion mechanisms, the relationship between mode of reproduction and plant invasion is not well understood. Fallopia japonica (Japanese knotweed), a highly aggressive invasive plant in both Europe and North America, serves as a model species for examining this relationship. In Britain, F. japonica var. japonica is a single female clone reproducing solely t...

Haminoea japonica is a species of opisthobranch sea slug native to Japan and Korea. Non-native populations have spread unnoticed for decades due to difficulties in the taxonomy of Haminoea species. Haminoea japonica is associated with a schistosome parasite in San Francisco Bay, thus further spread could have consequence to human health and economies. Anecdotal evidence suggests that H. japonic...

Two quinoline alkaloids, japonine (1) and eduline (2) were isolated from the methanol extract of the leaves of Orixa japonica as relaxants against rat small intestine muscle. The activity of these alkaloids was comparable to that of the typical muscle relaxant papaverine (4). This is also the first report of the isolation of eduline (2) from O. japonica.

Francisella tularensis is the etiological agent of the potentially fatal disease tularemia. Here, we report the draft genome sequence of a virulent human isolate from Tibet, China in 1962, F. tularensis strain 410108, an intermediate-genotype strain of F. tularensis subsp. holarctica between biovar japonica and non-japonica strains in the world.

Neoadenoloside A (1), an unprecedented diterpene C-glycoside with a unique C(26) framework, along with lasiokaurin (3) were isolated from the leaves of Isodon adenolomus. The absolute configuration of 2, a derivative of 1, was determined by spectroscopic methods and single-crystal X-ray diffraction analysis.

During natural parasitization, Asobara japonica wasps introduce lateral oviduct (LO) components into their Drosophila hosts soon after the venom injection to neutralize its strong toxicity; otherwise, the host will die. Although the orchestrated relationship between the venom and LO components necessary for successful parasitism has attracted the attention of many researchers in this field, the...

China is the first country to use heterosis successfully for commercial rice production. This study compared the main quality characteristics (head rice rate, chalky rice rate, chalkiness degree, gel consistency, amylose content, and length-to-width ratio) of 635 rice varieties (not including upland and glutinous rice) released from 2000 to 2014 to establish the quality status and offer suggest...

Questions: How do physical microsite conditions of microsites affect germination and seedling survival in different successional stages? Do different species germinate in similar microsites in a given successional stage? Location: Coleman Glacier foreland, Mount Baker, Washington State, USA. Methods: Two methods were used to characterize safe sites. 1. Grids of 300 10 cm × 10 cm plots were loca...

The terminal loop region of primary miRNA transcripts is an important determinant controlling miRNA function in human, animals and plants. However, the effects of polymorphisms in loop region of miRNA precusors on phenotypic variation have not been reported, especially on agronomic traits in rice. From rice japonica variety Koshihikari and indica Guichao2, we isolated a precursor of putative mi...
