(A) and (B) Root hair phenotype of wild-type and cys-c1 mutant plants, respectively, germinated and grown for 5 d in the absence of hydroxocobalamin.
(C) and (D) Root hair of wild-type and cys-c1 mutant plants, respectively, germinated and grown for 5 d in the presence of 5 mM hydroxocobalamin.
(E) and (F) Five-day-old wild-type and cys-c1 roots stained with NBT for superoxide detection.
(G) and (H) Five-day-old wild-type and cys-c1 mutant roots grown on hydroxocobalamin medium stained with NBT.
