Figure 6.
Relationship between N2 fixation rate and ΨL versus time after rewatering drought-stressed plants. Soybean plants (42 DAP) were inoculated with either ProDH+ or ProDH− strains of B. japonicum. N2 fixation rates are indicated by black symbols (circles for ProDH+ and triangles for ProDH−), and ΨL are indicated by white symbols (squares for ProDH+ and triangles for ProDH−).
