Size sensors in bacteria, cell cycle control, and size control

Bacteria proliferate by repetitive cycles of cellular growth and division. The progression into the cell cycle is admitted to be under the control of cell size. However, the molecular basis of this regulation is still unclear. Here I will discuss which mechanisms could allow coupling growth and division by sensing size and transmitting this information to the division machinery. Size sensors co...

Cell Size Control in Bacteria

Like eukaryotes, bacteria must coordinate division with growth to ensure cells are the appropriate size for a given environmental condition or developmental fate. As single-celled organisms, nutrient availability is one of the strongest influences on bacterial cell size. Classic physiological experiments conducted over four decades ago first demonstrated that cell size is directly correlated wi...

Cell-Size Control and Homeostasis in Bacteria

How cells control their size and maintain size homeostasis is a fundamental open question. Cell-size homeostasis has been discussed in the context of two major paradigms: "sizer," in which the cell actively monitors its size and triggers the cell cycle once it reaches a critical size, and "timer," in which the cell attempts to grow for a specific amount of time before division. These paradigms,...

Cell-Size Control.

Cells of a given type maintain a characteristic cell size to function efficiently in their ecological or organismal context. They achieve this through the regulation of growth rates or by actively sensing size and coupling this signal to cell division. We focus this review on potential size-sensing mechanisms, including geometric, external cue, and titration mechanisms. Mechanisms that titrate ...

Cell-size control

Cells usually grow to a proper size before they divide. To ensure an optimal size for cell survival and function, it is crucial that cells develop efficient and sensitive mechanisms for cell-size control. in 2009, 2 independent studies proposed that the DyRK-family kinase Pom1 could serve as a cell-length sensor to negatively regulate mitotic entry through sAD-like kinase Cdr2 in fission yeast....
