The Drosophila equivalent of the human transcription factor Sp8 acts to ensure that neural progenitor cells undergo an appropriate number of cell divisions, thereby helping to regulate brain development and guard against tumor formation.
Newly discovered interaction between fission yeast SPB and animal centriole components reveals that pericentrin not only functions as a microtubule-nucleator, but also promotes centriole assembly in animals.
A genetic screen and live cell imaging show that a newly identified coiled-coil protein called SAS-7 is the earliest acting factor in centriole assembly yet identified in the roundworm Caenorhabditis elegans.
The establishment of Ustilago bromivora and Brachypodium as a biotrophic model system provides the foundation for studying new aspects of plant-pathogen interactions and for answering questions about fungal sex and speciation.
Both the frequency of sesquiterpene-emitting individuals and the defense capacity of individual plants determine the consequences of sesquiterpene volatile emission for individuals and their neighbors in populations of the wild tobacco Nicotiana attenuata.
A previously unrecognized group of metalloenzymes enables human gut microbes to metabolize dietary molecules and neurotransmitters and likely mediates interactions and metabolism among environmental microorganisms.
