Polysomes isolated from a susceptible variety of wheat leaves (cultivar W2691) and those inoculated with the wheat stem rust fungus (f. sp. tritici, race 126-ANZ-6, 7) were incubated in a cell-free protein-synthesizing system. Under these conditions, different size classes of polypeptides, ranging in molecular weight from 10,000 to 80,000, are radiolabeled. Using double-isotope labeling technique, we show that some discrete size classes of polypeptides are synthesized in significantly greater quantitites by polysomes from inoculated leaves compared to the corresponding size classes synthesized by polysomes from healthy leaves. These results confirm our previous observation that there are significant changes in the wheat leaf polysomal messenger RNA populations at 3 days after inoculation with the rust fungus.The effects of the organelle-specific inhibitors of protein synthesis, chloramphenicol and lincomycin, on in vitro polysomal messenger RNA translation were investigated. The polypeptides synthesized by polysomes from healthy and inoculated leaves in the presence of chloramphenicol were compared. The results show that, even in the presence of this antibiotic, the polysomes from inoculated leaves synthesize greater quantities of some size classes of polypeptides. These data indicate that changes in polysomal messenger RNA populations involve, at least in part, cytoplasmic messenger RNA.
