Leaf-derived G3P is required for root exclusion of incompatible rhizobia. a Average number of nodules produced by U122 on grafts between Rj2 and rj2 genotypes. Genotype of rootstocks and scions are indicated in gray boxes below the x-axis. Boxed panels indicate grafts that produced nodules in response to U122. b Psg Vir counts on Rj2 and rj2 grafts pretreated (root) with buffer (MgCl2) or U122. Psg Vir was inoculated on scions 48 h after pretreatment of rootstocks with U122. LOG10 values of (CFU) colony forming units (cm) 2^-1 leaf area from infected leaves at 0 and 4 days post inoculation (dpi) are presented. Error bars indicate standard deviation (n = 4). Asterisks denote significant difference between mock and U122 plants of corresponding genotypes, Student’s t-test, P < 0.005. c Average number of nodules produced by U122 on grafts between control VIGS vector inoculated (V) and G3Pdh knockdown (SilG3Pdh) Rj2 plants. Asterisks denote significant differences from V × V grafts, t-test, P < 0.001.
