Phosphate deprivation counteracts the cell death caused by loss-of-function of MEDIATOR 18 in Arabidopsis root meristems
{{output}}
Mutation of MEDIATOR 18 leads to death of highly proliferating cells within the Arabidopsis root apical meristem, which impairs root growth. Phosphate (Pi) is a macronutrient required to support mitotic activity in meristems, and its deficiency causes root gro... ...
