Flagella are multiprotein complexes necessary for swimming and swarming motility. In Salmonella enterica serovar Typhimurium, flagella-mediated motility is repressed by the PhoP/PhoQ regulatory system ...
Many species of swimming bacteria have a rotary structure called a "flagellum," consisting of more than twenty different kinds of proteins. By rotating their flagellar filaments and gaining propulsion ...
Most motile bacteria move by the use of flagella. While the flagellar motor components have been identified, it remains unclear how they are assembled and activated. Researchers have now shown, ...
IN dark-ground microscopy with the sun as light-source, motile bacteria, when swimming fast, show a tail, as in the top left-hand photograph reproduced. This tail is occasionally seen to untwist into ...
Scientists at Tokyo Institute of Technology (Tokyo Tech) developed a motility-reactivation method to help determine how light-responsive changes in flagellar waveform in Volvox rousseletii, a ...
When looking at bacteria, you typically see also flagella: long hairs that protrudes from the bacteria's body. The key function of the flagella is movement - what scientists call 'motility'. The ...
The survival curves for a population of reactivated spermatozoa exposed to digestion by trypsin indicate that a large number of trypsin-sensitive targets must be digested before the flagellum ...
To build the machinery that enables bacteria to swim, over 50 proteins have to be assembled according to a logic and well-defined order to form the flagellum, the cellular equivalent of an offshore ...
Like humans, bacteria in most ecosystems live with limited resources. Therefore they are constantly faced with investment decisions: should they enhance motile behavior and thus be able to exploit new ...
Professor Takayuki Nishizaka and Dr. Yoshiaki Kinosita from Gakushuin University, together with Dr. Yoshitomo Kikuchi (Senior Researcher) from AIST, have discovered an unforeseen form of ...
(Nanowerk News) Bacteria swim in many different ways, and the motors that drive their swimming are widely varied, implying an adaptive response to an environment. One of the most commonly identified ...
