In order to study the effect of GA_3 on the phosphorylation of ribosomal proteins during germination in Zea mays, ribosomal proteins were labelled with ^32P, extracted, electrophoresed and autoradiographed. There are five phosphorylated ribosomal proteins. One of these is in 40S subunit and has molecular weight of 33,000 daltons. Others are in 60S subunit and have molecular weights of 37,000, 16,000, 15,200 and 13,500, respectively. Phosphorylation of ribosomal proteins was increased maximum 47.7% in shoots of Zea mays treated with GA_3.
