Inhibition of root hair deformation by treatment of roots with anti-LNP-serum. A comparison of root hairs 62 hours after inoculation of 3-day-old D. biflorus roots with the symbiont, Bradyrhizobium sp. 24A10. Before exposure to rhizobia, the roots of the plants were incubated for 1 hour in 1:100 dilutions of anti-LNP-serum (A) or preimmunization serum (B). Whole mounts of the roots were examined by phase-contrast microscopy. (Bar = 50 μm.)
