Signal discovered that connects cell size with cell growth

[28-02-2022]

The mechanisms connecting growth with cell size have been mysterious – up till now: in a recent publication in Current Biology, researchers from TU Delft and AMOLF have uncovered that the signaling molecule ppGpp is essential to regulate cell size. Surprisingly, they also discover cells adjust their sizes to concentrations of ppGpp, rather than strictly according to growth rate. Read more
