High P-use efficiency in Proteaceae includes a highly efficient and proficient mobilisation of P from senescing leaves. In addition, many species operate at extremely low leaf P concentrations exhibiting rates of photosynthesis similar to crop plant; expressed per unit leaf P, their rates of photosynthesis are extraordinarily high. I will explore what traits these species have that allow them to exhibit high rates of photosynthesis at very low leaf P concentrations.
