Pole-to-pole biogeography of surface and deep marine bacterial communities.
The Antarctic and Arctic regions offer a unique opportunity to test factors shaping biogeography of marine microbial communities because these regions are geographically far apart, yet share similar selection pressures. Here, we report a comprehensive comparison of bacterioplankton diversity between polar oceans, using standardized methods for pyrosequencing the V6 region of the small subunit r...
متن کاملBacterial sporulation: Pole-to-pole protein oscillation
Sporulating bacteria need to temporally coordinate DNA replication, chromosome partitioning and sporulation initiation. Recent work has shown that one aspect of this coordination lies with the interdependent subcellular localization of two proteins, Spo0J and Soj, and in the Spo0J-dependent spatial oscillation of Soj.
متن کاملXanthomonas citri MinC Oscillates from Pole to Pole to Ensure Proper Cell Division and Shape
Xanthomonas citri (Xac) is the causal agent of citrus canker, a disease that affects citrus crops and causes economic impact worldwide. To further characterize cell division in this plant pathogen, we investigated the role of the protein MinC in cell division, chromosome segregation, and peptidoglycan incorporation by deleting the gene minC using allele exchange. Xac with minC deleted exhibited...
متن کاملFrom 'third pole' to north pole: a Himalayan origin for the arctic fox.
The 'third pole' of the world is a fitting metaphor for the Himalayan-Tibetan Plateau, in allusion to its vast frozen terrain, rivalling the Arctic and Antarctic, at high altitude but low latitude. Living Tibetan and arctic mammals share adaptations to freezing temperatures such as long and thick winter fur in arctic muskox and Tibetan yak, and for carnivorans, a more predatory niche. Here, we ...
متن کاملThe Emerging Resurfacing History of Europa from Pole-to-pole Geologic
Introduction Geologic mapping of planetary surfaces provides information on the nature, sequence, and distribution of material units, from which one can assemble a geologic history [1]. With this goal in mind, the Galileo SSI camera acquired an important dataset of images of Europa at a resolution suitable for geologic reconnaissance and mapping. We performed mapping and analysis of pole-to-pol...
