From: Rhizobia use a pathogenic-like effector to hijack leguminous nodulation signalling

Nodulation of G. max cv. En1282 (nfr1 mutant soybean) inoculated with Bel2-5 ULP1 domain mutant strains. (a) The number of nodules formed on En1282 inoculated with wild-type and the mutants of predicted catalytic core of Bel2-5 ULP1 at 30 dai. Values represent mean ± SD (n = 15, from three independent inoculation tests). **p < 0.001 by two-tailed Student t-test compared to USDA61 wild-type. (b) Roots of En1282 inoculated with wild-type and the mutants of predicted catalytic core of Bel2-5 ULP1 were photographed at 30 dai. Scale bars: 1 cm.
