From: FixJ family regulator AcfR of Azorhizobium caulinodans is involved in symbiosis with the host plant
The ΔacfR mutant reduced nodulation competitiveness on roots and stems. The ΔacfR mutant was mixed at a 1:1, 1:5 or 1:10 with WT and inoculated onto roots and stems of S. rostrata. The complemented strain ΔacfR-C and WT was mixed at a 1:1 ratio. Data are shown the % of WT, mutant or complemented strain recovered from root nodules or stem nodules. At least 100 colonies that reisolated from randomly selected nodules from ten individual plants were identified and analyzed. The error bars represent the standard deviations of three independent experiments
