Role of filamentous phage SW1 in regulating the lateral flagella of Shewanella piezotolerans strain WP3 at low temperatures.

abstract：:Each year, thousands of new protistan 18S rRNA sequences are detected in environmental samples. Many of these sequences are molecular signatures of new protistan species, classes, and/or kingdoms that have never been seen before. The main goal of this study was to enable visualization of these novel organisms and to c...
