Phosphorus remobilisation from rice flag leaves during grain filling.. Rice phosphorus remobilisation

The physiology and molecular regulation of phosphorus (P) remobilisation from vegetative tissues to developing grains during grain filling plays a pivotal role in the global P cycle yet little is known about this process. We conducted a RNA-seq transcriptome analysis of the rice flag leaf when P concentration was stable (6 DAA) and when the leaf was acting as a P source (15 DAA) to test the hypothesis that a subset of genes involved in the P starvation response are involved in remobilisation of P from flag leaves to the seeds during grain filling.
