Abstract: | Abstract: In acidic soils with Mn toxicity, the development of an intact arbuscular mycorrhiza
extraradical mycelium (ERM) by stress-adapted native plants can promote increased growth and
protection against metal toxicity, in subsequent crops. In a recent study, the growth of Ornithopus
compressus (ORN) in acidic soil doubled shoot weight, increased P contents and decreased shoot Mn
in successive wheat crops. The biochemical mechanisms involved in this beneficial effect may include
the subcellular redistribution of nutrients and of excess Mn. In the present work, shoot Ca, Fe, Mg,
Mn, P, K, Si, Na and Zn were mapped through Laser Ablation-Inductively Coupled Plasma Mass
Spectrometry (LA-ICP-MS), in wheat grown for 3 weeks in undisturbed soil, where ORN previously
developed an extensive ERM network. Element mapping allowed for the detection of higher levels
of Fe, Mg, Mn, P, K, Na and Zn in the interveinal sections of wheat leaves while Ca and Si showed
higher levels in vascular zones of the adaxial side. This preliminary work is part of an ongoing
project which aims at identifying biochemical mechanisms responsible for the protective properties
of an early AM colonization of crops, by ERM previously developed in association with native plants
under Mn toxicity. Future research will determine the subcellular redistribution of these elements
and excess Mn. |
