Nitrate transporter NRT2.1 is a determinant of a nitrogen acquisition switch between nitrate uptake and symbiosis in Lotus japonicus (Plant Cell)

When nitrogen or nitrate availability is high, symbiotic nodule generation is curtailed to conserve the associated energy cost. But how does the presence of nitrate interfere with nodulation and symbiosis?  Previously, genetic studies identified nitrate unresponsive symbiosis (nrsym) mutants in Lotus…
