In our recent study, published in New Phytologist, we have assessed the implications that phosphorus (P) availability and phylogenetic constraints may have for P compartmentation in eudicots. We showed that P allocation to different cell types may differ depending on the soil P availability in the area where species evolved, and that there is no phylogenetic pattern in P allocation within eudicots. We surmise that preferential allocation of P to mesophyll cells is a trait that evolved multiple times in response to severe P limitation, which is at variance with the prevailing model that eudicots exhibit a single P-allocation pattern. We also discussed the implications that interfering elements, such as calcium and aluminium, may have on P-allocation patterns.
