ppGpp is a bacterial cell size regulator

Growth and division are central to cell size. Bacteria achieve size homeostasis by dividing when growth has added a constant size since birth, termed the adder principle, by unknown mechanisms.¹^,² Growth is well known to be regulated by guanosine tetraphosphate (ppGpp), which controls diverse processes from...

The role of ppGpp in E. coli cell size control

Bacteria have been an integral part of human life since the ancient times either as cooperative tenants living in and around us or as constant threats to our health and wellbeing. Since prehistoric times we unknowingly used them as tools of fermentation and fought against them with haphazardly discovered natural remedies. Today, after more than...
