New Paper in Journal of Experimental Botany

In our recent study, published in Journal of Experimental Botany, we show that increasing calcium (Ca) supply enhanced the preferential allocation of phosphorus (P) to palisade mesophyll cells under high P conditions, without a significant change in whole leaf [P]. Calcifuges showed a greater palisade mesophyll [P] compared with soil-indifferent species, corresponding with their greater sensitivity. This study advances our mechanistic understanding of Ca-enhanced P toxicity, demonstrating its role in the calcifuge distribution of Proteaceae.

I'm happy to announce that I have been offered an appointment as a Visiting Fellow of the Arnold Arboretum of Harvard University! I'll be conducting a series of experiments there during this summer, mostly focusing on the molecular mechanisms of resource allocation in Brachypodium.

New Paper in Journal of Ecology

In our recent study, published in Journal of Ecology, we show that with declining soil phosphorus (P) availability across the Jurien Bay dune chronosequence (south-western Australia), the photosynthetic P-use efficiency (PPUE) of all investigated species from different families increased. Plants growing on the oldest, most nutrient‐impoverished soils exhibited similar CO2-exchange rates as plants growing on nutrient‐richer, younger soils, and extraordinarily high PPUE. This indicates convergence in leaf traits related to photosynthetic nutrient use on severely P‐impoverished sites.

In our recent study, published in New Phytologist, we provide the first demonstration of calcium‐enhanced phosphorus toxicity across multiple Proteaceae species. We surmise that this phenomenon might partially explain the calcifuge habit of most Proteaceae and is therefore critical for the management of this iconic Australian family. This study represents a major advance towards an understanding of the physiological mechanisms of phosphorus toxicity and its role in the distribution of Proteaceae.

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.
