Not all arbuscules pull the same weight
Arbuscular mycorrhizal (AM) fungi trade soil phosphate for plant carbon at arbuscules, the short-lived, branched hyphal structures they build inside root cortical cells, but how phosphate uptake is coordinated across this constantly changing interface has been hard to observe. McGaley et al. used non-invasive, time-lapse confocal imaging of live rice roots to follow individual arbuscules […]
