Bioenergetics of pollen tube growth in Arabidopsis thaliana revealed by ratiometric genetically encoded biosensors

Abstract

Pollen tube growth involves coordinated energy fluxes between plastids, the cytosol, and mitochondria. Here using ratiometric biosensors, the authors delineate energy flux in growing Arabidopsis pollen tubes by monitoring ATP, NADPH and the NADH/NAD + ratio at the subcellular level.
