R. mucilaginosa JGTA-S1 Associates with Roots and Promotes Plant Growth in Rice.

Four- to 5-d-old rice plants of equal length were grown in Soilrite supplemented with MS medium (N-replete conditions) with or without JGTA-S1. Plant growth was measured at 3 wpi by monitoring.

(A) Shoot length, root length (control, n = 25; treated, n = 23), and dry mass (control, n = 23; treated, n = 27). (Left) Digital image of control and treated rice. Bar =5 cm. (Right) Mann-Whitney test for shoot length, root length, and total dry mass values (***P-value < 0.001, **P-value 0.001 to 0.01).

(B) and (C) Yeast attached to rice roots or root sections stained with lactophenol cotton blue. Binucleated telial cells attached to rice root cells (see [B], arrowheads). Bar = 5 µm. Yeast cells within the rice root section (see [C]). Bar = 10 µm.
