High-Temperature Live-Cell Imaging Of Cytokinesis, Cell Motility, And Cell-Cell Interactions In The Thermoacidophilic Crenarchaeon Sulfolobus Acidocaldarius
FRONTIERS IN MICROBIOLOGY(2021)
摘要
Significant technical challenges have limited the study of extremophile cell biology. Here we describe a system for imaging samples at 75 degrees C using high numerical aperture, oil-immersion lenses. With this system we observed and quantified the dynamics of cell division in the model thermoacidophilic crenarchaeon Sulfolobus acidocaldarius with unprecedented resolution. In addition, we observed previously undescribed dynamic cell shape changes, cell motility, and cell-cell interactions, shedding significant new light on the high-temperature lifestyle of this organism.
