Auxin-Producing Pseudomonas Recruited by Root Flavonoids Increases Rice Rhizosheath Formation through the Bacterial Histidine Kinase Under Soil Drying.

ABSTRACT: Rhizosheath formation is facilitated by root hair length, root exudates, the soil microbes, which collectively enhance plant resistance to drought. This process partly results from the complex interaction between root exudates and microbes, a relationship that remains poorly understood. The roles of root exudates and microbes in rhizosheath formation in rice under soil drying (SD) conditions are investigated. In tetraploid rice, rhizosheath formation under SD is approximately 70% greater than in diploid rice. Inoculation of diploid rice with the rhizosheath soil microbiota from tetraploid rice significantly enhanced rhizosheath formation under SD. The bacterial genus Pseudomonas is identified as the key taxon promoting rhizosheath formation in tetraploid rice under SD. Tetraploid rice exhi
