Comparison of Aspartate Transcarbamoylase Activity Between Pseudomonas Aeruginosa Which Has One Chromosome and Burkholderia Cepacia Which Has Three Chromosomes

Description: The pyrimidine biosynthetic pathway is essential and similar in all bacteria. The pathway from Pseudomonas is regulated by nucleotides which bind to the upstream region of the pyrBC’ gene complex. Work in our lab mapped the genes and showed that the pyrB and pyrC’ were part of an overlap complex. The Pseudomonas aeruginosa has one circular chromosome. A former Pseudomonas now called Burkholderia cepacia is similar to P. aeruginosa except that it contains three circular chromosomes (CI, CII, … more

Studies on Plant-aphid Interactions: a Novel Role for Trehalose Metabolism in Arabidopsis Defense Against Green Peach Aphid

Description: Myzus persicae (Sülzer), commonly known as the green peach aphid (GPA), is a polyphagous insect that can infest over 100 families of economically important plants and is major pest for vegetable crops. This study utilizes the Arabidopsis-GPA model system with the aim to elucidate the role of the plant disaccharide trehalose in providing defense against GPA. This study demonstrates a novel role for TPS11 in providing defense against GPA. TPS11 expression was found to be transiently induced in Ar… more

Zebrafish Von Willebrand Factor

Description: In humans, von Willebrand factor (vWF) is a key component in hemostasis and acts as a 'cellular adhesive' by letting the circulating platelets bind to exposed subendothelium. It also acts as a carrier and stabilizer of factor VIII (FVIII). A dysfunction or reduction of vWF leads to von Willebrand disease (vWD), resulting in bleeding phenotype which affects 1% of the population. Currently there are a variety of animal models used for the study of vWF and vWD; however, they do not possess the … more
