Connecting the dots between PubMed abstracts
( Public Library of Science , 2012 , Article)Background: There are now a multitude of articles published in a diversity of journals providing information about genes, proteins, pathways, and diseases. Each article investigates subsets of a biological process, but to ... -
Consequences of marine barriers for genetic diversity of the coral-specialist yellowbar angelfish from the Northwestern Indian Ocean
( John Wiley and Sons Ltd , 2019 , Article)Ocean circulation, geological history, geographic distance, and seascape heterogeneity play an important role in phylogeography of coral‐dependent fishes. Here, we investigate potential genetic population structure within ... -
Considering the Specific Impact of Harsh Conditions and Oil Weathering on Diversity, Adaptation, and Activity of Hydrocarbon-Degrading Bacteria in Strategies of Bioremediation of Harsh Oily-Polluted Soils
( Hindawi Publishing Corporation , 2017 , Article)Weathering processes change properties and composition of spilled oil, representing the main reason of failure of bioaugmentation strategies. Our purpose was to investigate the metabolic adaptation of hydrocarbon-degrading ... -
Construction of a Bacillus thuringiensis genetically-engineered strain harbouring the secreted Cry1Ia delta-endotoxin in its crystal
( Springer Netherlands , 2011 , Article)Unlike other Bacillus thuringiensis Cry proteins, Cry1 Ia does not form a crystal since it is a secreted delta-endotoxin. We have engineered a Cry1 Iac chimeric protein by substituting the C-terminal part of Cry1 Ia by the ... -
Consumers' Perception and Attitudes Towards Safety of Fruits and Vegetables in Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Qatar is well known for its natural resources and the country has the highest per capita income in the world, but when it comes to food, the picture is different. The country imports nearly 90% of its food, meaning it is ... -
Contrasting effects of necrotrophic and biotrophic plant pathogens on the aphid Aphis fabae
( John Wiley & Sons Ltd. , 2013 , Article)Phytophagous insects have to contend with a wide variation in food quality brought about by a variety of factors intrinsic and extrinsic to the plant. One of the most important factors is infection by plant pathogenic ... -
