Abstract

Low-molecular RNP or prosomes with sedimentation coefficient of 19 S and 10 S, which are being discovered only in cytoplasmatic mKNPs are absent in mRNP polysomes are isolated. The value of buoyant density of extracted structures in preformated gradient Cs2SO4 DMSO corresponds to 1,31 g/cm3 .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.
