Globoids in roots accumulate phosphorus to extremely high concentrations following a sudden increase in phosphorus availability Crops with enhanced uptake of fertiliser-phosphorus (P) would confer environmental benefits. We examined how roots of P-sufficient 6-week-old soil-grown plants and 2-week-old seedlings in solution culture of Trifolium subterraneum stored P following P addition. We expected cell vacuoles to store excess P. After 1 week, microanalysis showed cell vacuole [P] remained low (< 12 mmol kg–1). However, post- (plants) and pre- and post-P addition (seedlings), some cortex cells contained large globular s......[More] University of Western Australia
