2022, Field Crops ResearchCitation Excerpt :Formation of aerenchyma in crops enables an efficient exchange of gases between the atmosphere and the root tip (Kludze et al., 1993). The transport of oxygen from the atmosphere into the root rhizosphere (Nouchi et al., 1990) not only maintains the aerobic metabolism of roots and microbes; but also inhibits movement of toxic substances such as Fe2+, Mn2+, and H2S into the roots by oxidation (Armstrong et al., 1991; Neue and Bloom, 1989). Stored oxygen is also used to fuel the activity of various ion pumps and carriers, to maintain normal nutrient acquisition (Shabala and Pottosin, 2014).

2021, Science of the Total EnvironmentCitation Excerpt :For instance, the surfaces of root cell walls could be relatively anoxic as root oxygen cannot leak through them (Neubauer et al., 2008). Previous studies reported that the mean diameter (10–20 μm) of these cell walls is spacious enough for the accumulation of Fe-reducing bacteria (mean diameter: 0.4–0.9 μm) (Armstrong et al., 1991; Neubauer et al., 2008; Weiss et al., 2002). Nevertheless, the enrichment of Fe-reducing bacteria and non-sulfidic Fe(II) indicates that the rhizosphere effect favors rapid microbial Fe(III) reduction in the rhizosphere.
