dc.description.abstractSelenium (Sc) is an important antioxidant considered among the fertilization programs in developed countries. In Chile, chemical fertilization based in Se is inefficient due the physicochemical characteristics of Andisol that sustain the 60% of crop production. Andisol also are highly conductive to take-all disease caused by Gaeuman-nonyces graminis var tritici (Ggt). Here, we evaluated the effect of Bacillus sp.E5 and Acinetobacter sp.E6.2 and Clamideoglomus claroideum as potential inocula for Se biofortification and Ggt bicontrol in wheat. Plants inoculated with Acinetobacter sp.E6.2 showed major root growth and major Se content in shoots and grains. The antioxidant role of Se regarding DPPH activity was shown in Se-supplemented plants with small Se nanoparticks founded inside the roots. Mycorrhizal plants showed major SOD activity in shoots but no affected the Se uptake. Respect to pathogen biocontrol, plants inoculated with both bacteria showed an efficient control against Ggt independent to myconhization. Thus, our inocula could make important contributions to produce enriched Se flours for human nutrition and biocontrol against Ggt.
