Autoradiography of immunoprecipitated SS from maize seedling roots, labeled in vivo with ³²P_i under long-term anoxia. A, Labeling was for 4 h of anoxia after an aerobic pre-incubation of non-mutant and sus1 seedlings with ³²P for 2 h. B, Labeling was carried out during the final 3 h of a 48-h anoxic treatment of non-mutant and sh1 seedlings. Air, Aerobic incubation; S, anoxia; NM, non-mutant
