We present here the first complete genome sequences of Sweet potato virus 2 (SPV2) from sweet potato in Australia and East Timor, and compare these with five complete SPV2 genome sequences from South Korea and one each from Spain and the United States. Both were closely related to SPV2 genomes from South Korea, Spain, and the United States.

We present here the first complete genome sequences of Sweet potato chlorotic fleck virus (SPCFV) from sweet potato in Australia and East Timor, and we compare these with four complete SPCFV genomes from South Korea and one from Uganda. The Australian, East Timorese, South Korean, and Ugandan genomes differed considerably from each other.

Background: The advent of recombinant DNA technology has facilitated heterologous expression of proteins from various sources in different host systems including Escherichia coli. If a plant virus coat protein is expressed in the bacterium it can be used as the antigen for antibody preparation. Such a recombinant antigen preparation can be particularly useful where equipment such as ultracentri...

The effects of the phototoxic K+- channel blockers 8-methoxypsoralen (8-MOP) and 5-methoxypsoralen (5-MOP) on Ranvier nodes were compared to those of 5,8-diethoxypsoralen (5,8-EOP) by means of the Hodgkin-Huxley formalism. When these test substances were added individually to the bathing solution (8-MOP: 100 micromol/l; 5-MOP: 50 micromol/l; 5,8-EOP: 10 micromol/l) the following completely reve...

Background: Potyviruses are accounted for 40% of viral diseases of various crops including vegetables and legumes. Potyviruses can be transmitted through plant sap, seeds and many aphid species. Due to ease of spread of these viruses detection of such viruses are crucial as to the control of the incited diseases. Objectives: This study compared the efficiencies of two couples of primers in the...

The common assumption in potato virus epidemiology is that all daughter tubers produced by plants coming from infected mother tubers (secondary infection) will become infected via systemic translocation of the virus during growth. We hypothesize that depending on the prevalent environmental conditions, only a portion of the daughter tubers of a plant that is secondarily infected by viruses may ...

The μ-opioid receptor (MOP) is a subtype that belongs to the superfamily of 7-transmembranespanning G-protein-coupled receptors. Pharmacological studies with gene-knockout mice show that MOP is a major target for the clinically important opioid drugs, such as morphine and fentanyl, and it appears to play critical roles in the mediation of the major effects of these opioid drugs, including analg...

Adapting to user’s requirements is a key factor for enterprise success. Despite the existence of several approaches that point in this direction, simplifying integration and interoperability among users, suppliers and the enterprise during product lifecycle, is still an open issue. Ontologies have been used in some manufacturing applications and they promise to be a valid approach to model manu...
