We report cell-to-cell movement of mitochondria through a graft junction. Mitochondrial movement was discovered in an experiment designed to select for chloroplast transfer from Nicotiana sylvestris into Nicotiana tabacum cells. The alloplasmic N. tabacum line we used carries Nicotiana undulata cytoplasmic genomes, and its flowers are male sterile due to the foreign mitochondrial genome. Thus, ...

The stylasterid fauna of Alaska is revised, consisting of the description or redescription and illustration of 21 species, one additional subspecies, and a geographically adjacent species: Stylaster venustus. Six new species and one new subspecies are described: Errinopora fisheri, Errinopora undulata, Errinopora disticha, Errinopora dichotoma, Stylaster crassiseptum, Stylaster repandus, and St...

Aqueous extracts of nine plants, known to have medicinal activity, were tested for their toxicity against the sweet potato whitefly, Bemisia tabaci Genn. (Homoptera: Aleurodidae) compared to the toxicity of the insecticide, Imidacloprid. Extracts of Lepidiuim sativum L. (Brassicales: Brassicaceae) killed 71 % of early stage nymphs, which was not significantly different from mortality caused by ...

This dataset records the occurrence and inventory of molluscan fauna on Gueishan Island, the only active volcanic island in Taiwan, based on the literature survey and field investigation conducted between 2011 and 2012. The literature review involved seven studies published from 1934 to 2003, which collectively reported 112 species from 61 genera and 37 families of Mollusca on Gueishan Island. ...

Highly diverse plant communities growing on nutrient-impoverished soils are test beds for theories species coexistence. Here, neighbouring mycorrhizal and non-mycorrhizal plants compete limited phosphorus. The impact of below-ground interactions community dynamics is underexplored. We used an experimental approach to investigate effects inoculation with arbuscular (AM) fungi a phosphorus supply...

In object-oriented systems, object associations generally result in a complex structure whose precise description is a crucial part of the sys-tem's formal speciication. A particularly common object association arises when one object exclusively controls (owns) another. As exclusive object control is an important aspect of safety and security critical systems, speciic notation to capture direct...

This paper specifies the formal semantics of XSLT. Using Object-Z specification language to describe each constructs of the language as objects, the stylesheet itself was specified by underlying objects. This work will contribute to the implementation of XSLT.

Human pythiosis is a life-threatening infectious disease caused by the oomycete Pythium insidiosum. Diagnosis of pythiosis relies on culture identification, serodiagnosis, and molecular-based assay. Preparation of a serodiagnostic test requires culture filtrate antigen (CFA) extracted from the live pathogen. A 74-kDa immunoreactive protein of P. insidiosum, is encoded by the exo-1,3-beta-glucan...

The purpose of this study was to isolate and select indigenous soil Pseudomonas and Bacillus bacteria capable of developing multiple mechanisms of action related to the biocontrol of phytopathogenic fungi affecting soybean crops. The screening procedure consisted of antagonism tests against a panel of phytopathogenic fungi, taxonomic identification, detection by PCR of several genes related to ...
