Leymus chinensis resists degraded soil stress by modulating root exudate components to attract beneficial microorganisms.

ABSTRACT: Phytoremediation is an effective means to improve degraded soil nutrients and soil structure. Here, we investigated the remediation effects of Leymus chinensis on the physicochemical properties and structure of degraded soil after 3 years of cultivation and explored the bacterial and fungal drivers in root exudates by metabolomics and high-throughput sequencing. The results showed that root exudates increased soil organic matter (SOM), total nitrogen (TN), total phosphorus (TP) and soil aggregates, and organic acids in root exudates reduced pH and activated insoluble nutrients into forms that are available to plants, such as available nitrogen (NH₄ ⁺-N), nitrate nitrogen (NO₃ ^--N), and available phosphorus (AP). The cultivation of L. ch
