Swine populations worldwide are sporadically infected by influenza viruses from humans and birds leading to geographically heterogeneous swine influenza virus populations that pose epizootic and pandemic threats.
An iron-sensitive gene cluster encodes proteins that co-localize with phytotransferrin endosomes and are involved in key intracellular iron transformation and trafficking processes in a model marine diatom.
Standing genetic variation for disease resistance may be continuously lost during recurring warm water episodes because of widespread susceptibility of disease-resistant genotypes to bleaching and the independence between these two traits.
Analysis of a spermiogenesis protein reveals a new chromatin requirement for synchrony between maternal DNA packaged in the egg and sperm-packaged paternal DNA in the first embryonic mitosis in Drosophila melanogaster.
Dynamic successive blooms of clades of planktonic marine bacteria that can be observed during blooms of marine algae follow discernible patterns, part of which might be explained by substrate-induced forcing.
