“…P availability in soil affects the structure and abundance of gcd-harboring bacterial communities. Previous studies have shown that the diversity and abundance of phosphate solubilizing bacteria (PSB) increase (Pastore et al, 2020;Spohn et al, 2020) or decrease (Bergkemper et al, 2016b;Kurth et al, 2020) at forest sites with low P availability. Further gcd expression is directly controlled by phosphate concentration (Zeng et al, 2016).…”

“…earlier to respond to P (and Fe) deficiency by exuding higher amounts of the same LMWOA for which we found the largest increases in intercropping (Carvalhais et al, 2011;Gaume et al, 2001). The exudation of LMWOA is commonly increased in response to P (and Fe) deficiency by many plant species (Canarini et al, 2019;Spohn et al, 2020;Y. Wang & Lambers, 2020).…”

“…Maize has been found earlier to respond to P (and Fe) deficiency by exuding higher amounts of the same LMWOA for which we found the largest increases in intercropping (Carvalhais et al, 2011; Gaume et al, 2001). The exudation of LMWOA is commonly increased in response to P (and Fe) deficiency by many plant species (Canarini et al, 2019; Spohn et al, 2020; Y. Wang & Lambers, 2020). Hence, the increased LMWOA exudation by maize in intercropping compared to monocropping might additionally be explained by high interspecific competition for P (and Fe) since the companion plants took up more P than maize.…”

“…Compared to the surrounding bulk soil (BS), 50 to 90% of the mineralosphere-bacteria tested are effective at weathering while only 20% in BS. All these studies highlighted that higher frequencies of MWe bacteria are observed on less weatherable (e.g., obsidian) and weathered minerals (calcite) than on highly weatherable minerals [42][43][44][45][46][47]49].…”
