A Tripartite Interaction among the Basidiomycete , N-Fixing Endobacteria, and Rice Improves Plant Nitrogen Nutrition.

Nitrogen (N) limits crop yield, and improvement of N nutrition remains a key goal for crop research; one approach to improve N nutrition is identifying plant-interacting, N-fixing microbes. JGTA-S1 is a basidiomycetous yeast endophyte of narrowleaf cattail (). JGTA-S1 could not convert nitrate or nitrite to ammonium but harbors diazotrophic (N-fixing) endobacteria () that allow JGTA-S1 to fix N and grow in a N-free environment; moreover, dinitrogen reductase was transcribed in JGTA-S1 even under adequate N.
