Since proteaceous species produce proteoid roots that mobilise nutrients such as Mn in the root-zone by organic acid secretion (Shane and Lambers 2005), this may explain the efficient acquisition of Mn by G.
The story from South Africa, was that in the fynbos, where proteaceous plants abound, bugs are 'thin on the ground.
The plants selected were Hardenbergia comptoniana (Hc), a vigorous creeping ground cover legume; Acacia cyclops (Ac), a legume shrub; Grevillea crithmifolia (Gc), a proteaceous shrub; and Eucalyptus gomphocephala (Eg), a tree.
Many proteaceous species produce proteoid roots that mobilise nutrients such as Mn and P in the root-zone by organic acid secretion (Shane and Lambers 2005).
So far, no leaf fossils are known from the Mesozoic that are convincingly proteaceous.
This lack of Proteaceae may reflect the fact that fossil pollen from New Zealand Cretaceous sediments do not show anywhere near the same extent of proteaceous diversification as in southeastern Australia (Pole, 1998).
