The Roslin Institute, University of Edinburgh, Easter Bush Campus, Midlothian, Edinburgh EH25 9RG, UK; Euan MacDonald Centre, Chancellor's Building, University of Edinburgh, 49 Little France Crescent, Edinburgh EH16 4SB, UK; Centre for Dementia Prevention, University of Edinburgh, 9A Bioquarter, 9 Little France Road, Edinburgh EH16 4UX, UK. Electronic address:

Normal mammalian brain aging is characterized by the selective loss of discrete populations of dendritic spines and synapses, particularly affecting neuroanatomical regions such as the hippocampus. Although previous investigations have quantified this morphologically, the molecular pathways orchestrating preferential synaptic vulnerability remain to be elucidated. Using quantitative proteomics and healthy rhesus macaque and human patient brain regional tissues, we have comprehensively profiled the temporal expression of the synaptic proteome throughout the adult lifespan in differentially vulnerable brain regions.

Life table invasion models: spatial progression and species-specific partitioning.

Ecology 2019 Apr 24:e02682. Epub 2019 Apr 24.

Department of Entomology, University of California, Davis, California, 95616, USA.

Biological invasions are increasingly being considered important spatial processes that drive global changes, threatening biodiversity, regional economies, and ecosystem functions. A unifying conceptual model of the invasion dynamics could serve as a useful tool for comparison and classification of invasion processes involving different species across large geographic ranges. By dividing these geographic ranges that are subject to invasions into discrete spatial units, we here conceptualize the invasion process as the transition from pristine to invaded spatial units.

Soil carbonate drives local adaptation in Arabidopsis thaliana.

Plant Cell Environ 2019 Apr 24. Epub 2019 Apr 24.

Plant Physiology Lab, Bioscience Faculty, Universidad Autónoma de Barcelona.

High soil carbonate limits crop performance especially in semi-arid or arid climates. To understand how plants adapt to such soils, we explored natural variation in tolerance to soil carbonate in small local populations (demes) of Arabidopsis thaliana growing on soils differing in carbonate content. Reciprocal field-based transplants on soils with elevated carbonate (+C) and without carbonate (-C) over several years revealed that demes native to (+C) soils showed higher fitness than those native to (-C) soils when both were grown together on carbonate-rich soil.

Unmasking cellular response of a bloom-forming alga to viral infection by resolving expression profiles at a single-cell level.

PLoS Pathog 2019 Apr 24;15(4):e1007708. Epub 2019 Apr 24.

Department of Plant and Environmental Sciences, Weizmann Institute of Science, Rehovot, Israel.

Infection by large dsDNA viruses can lead to a profound alteration of host transcriptome and metabolome in order to provide essential building blocks to support the high metabolic demand for viral assembly and egress. Host response to viral infection can typically lead to diverse phenotypic outcome that include shift in host life cycle and activation of anti-viral defense response. Nevertheless, there is a major bottleneck to discern between viral hijacking strategies and host defense responses when averaging bulk population response. Read More

Microtubule bundling by MAP65-1 protects against severing by inhibiting the binding of katanin.

Mol Biol Cell 2019 Apr 24:mbcE18120776. Epub 2019 Apr 24.

Department of Biology and Center for Engineering Mechanobiology, Washington University in St. Louis, St. Louis, MO 63130, USA.

The microtubule-severing enzyme katanin regulates the organization and turnover of microtubule arrays by the localized breakdown of microtubule polymers. In land plants, katanin (KTN1) activity is essential for the formation of linearly organized cortical microtubule arrays which determine the axis of cell expansion. Cell biological studies have shown that even though KTN1 binds to the sidewalls of single and bundled microtubules, severing activity is restricted to microtubule crossover and nucleation sites, indicating that cells contain protective mechanisms to prevent indiscriminate microtubule severing.
