Low-molecular RNP or prosomes with sedimentation coefficient of 19 S and 10 S, which are being dis¬covered only in cytoplasmatic mKNPs are absent in mRNP polysomes are isolated. The value of buoyant density of extracted structures in preformated gradient Cs2SO4 DM SO corresponds to 1,31 g/cm .On the basic of healthy and infected by potato virus X plants the protein composition of prosomes is defined. From prosomes preparation the low-molecular 4 S RNA is extracted.
