Lineage sorting and introgression can lead to incongruence among gene phylogenies, complicating the inference of species trees for large groups of taxa that have recently and rapidly radiated. In addition, it can be difficult to determine which of these processes is responsible for this incongruence. We explore these issues with the radiation of New Zealand(More)
Endochitinases are widely distributed among higher plants, including a number of important crop species. They are generally considered to be involved in plant defence against potential pathogens. We have cloned a class IV chitinase gene (AtchitIV) from Arabidopsis thaliana. Southern blot analysis allowed the detection of two cross-hybridising genes in the(More)
The early response to bacterial inoculation has been investigated and two Arabidopsis genes, ap3.3a and ap4.3a have been characterized. The AP3.3A protein showed high identity to centrin, a ubiquitous cytoskeletal protein first identified in unicellular green alga. Amino-acid sequence analyses of the AP4.3A protein indicates that the second gene(More)

Background: Antivenoms are believed to have limited shelf lives. Research indicates antivenom activity may surpass expiration dates. Research question: Does binding of antivenom to venom persist after expiration date? Methods: Fluorescent immunoassays compared binding of antivenom to venom. Ninety-six well plates were coated with venom, incubated with(More)
Opioid overdose is a leading cause of death in the USA. Internet-based teaching can improve medical knowledge among trainees, but there are limited data to show the effect of Internet-based teaching on clinical competence in medical training, including management of opioid poisoning. We used an ecological design to assess the effect of an Internet-based(More)
