Filamentation can also be induced by signalling factors produced by other bacteria. [29] In addition, Agrobacterium spp. filament in proximity to plant roots, [30] and E. coli filaments when exposed to plant extracts. [31] Lastly, bacteriophage infection can result in filamentation via the expression of proteins that inhibit divisome assembly. [8]
Filamentation occurs as a direct response to these effectors that are produced by the predator and there is a size preference for grazing that varies for each species of protist. [1] The filamentous bacteria that are larger than 7 μm in length are generally inedible by marine protists. This morphological class is called grazing resistant. [13]
Inhibition of FtsZ disrupts septum formation, resulting in filamentation of bacterial cells (top right of electron micrograph).. During cell division, FtsZ is the first protein to move to the division site, and is essential for recruiting other proteins that produce a new cell wall between the dividing cells.
[3] [4] Later, by characterizing the phenotypes of mutagenised E. coli, she and post doctoral student Miroslav Radman detailed the SOS response to UV radiation in bacteria. [3] [5] The SOS response to DNA damage was a seminal discovery because it was the first coordinated stress response to be elucidated. [6]
These are called epigenetic changes, and they accumulate throughout an individual’s life due to many factors, including diet. Methylation is the most common type of epigenetic change ...
