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.
