Fig. 5: sup3, but not bel2-5, complements nodulation of ORS3257∆ernA mutant.

A Symbiotic phenotypes of ORS3257 and various derivatives of the ORS3257∆ernA mutant carrying ernA, sup3 and bel2-5 genes (∆ernA::ernAORS3257; ∆ernA::sup3NAS96.2; ORS3257∆ernA::sup3WSM1744; ORS3257∆ernA::bel2-5) (scale bars: left 0.5 cm, right 0.2 cm). B Nodule number on A. indica plants at 21 days after inoculation with ORS3257 and the ORS3257∆ernA mutant derivatives. Box plots show the results of one of the two experiments performed independently (8 plants each). *p ≤ 0.01, **p < 0.005, ****p < 0.0001, significant differences between the wild-type strain and each mutant using a parametric Welch test.
