内容記述 Five-mm sections of elongation zones which were cut from primary roots or coleoptiles of Zea mays were incubated for designated periods with various concentrations of IAA. In vitro protein phosphorylation in the soluble fractionsprepared from these sections was analyzed by SDS-PAGE. The phosphorylation of proteins in sections of primary roots incubated for 20 or 40 min in the presenceof 10^-7 M IAA was greater than that in the sections incubated in the absence ofIAA. The phosphorylation of proteins in sections of primary roots incubated for 20 min or 2h in the presence of 10^-8,10^-7 or 10^-6 M IAA was higher than that in the sections incubated in the absence of IAA. An incuba-tion for 20 min or 2h with 10^-4 M IAA inhibited the phosphorylation of proteins in sections of primary roots. The growth of the sections of primary roots incubated for 2h in the presence of 10^-7 M IAA or higher concentrations was lower than that of the sections incubated in the absence of IAA. These results suggest that the phosphorylation of proteins which was increased by IAA treatment is independent of an inhibition of the growth induced by IAA in maize primary roots. The phosphorylation of proteins in sections of coleoptiles incubated for 10, 20 or 40 min in the presence of 10^-7 or 10^-5 M IAA was equal to that in the sectionsincubated in the absence of IAA. These results show that IAA regulates growth ofmaize coleoptiles in no relation with phosphorylation of the proteins and that IAA regulates growth of maize mesocotyls via phosphorylation of the proteins, comparing with earlier results [Kato et al. (1996) Plant Cell Phsiol. 37:667]. Coleoptile―IAA treatment―Primary root―Protein phosphorylation―Zea mays.
