The PolVol team was composed of two students, one studying at the Université de Montréal (Canada) and another on exchange from the Université de Rouen (France). The team investigated how plant cells adapt their metabolism to changes in gravity. More specifically, they determined how the intracellular dynamics of pollen tubes are affected by hypergravity. A video camera attached to a fluorescent microscope inside an LDC gondola was used to obtain images of the growing pollen tubes whilst they were subjected to hypergravity. A dye injected into the growth medium was used to highlight changes.
