[Electrophoretic study of the proteins from Actinidia leaves and sex identification].

The protein composition of actinidia (Actinidia L.) leaves has been studied by SDS-PAGE. Specific polypeptides in the protein pattern of male and female plants belonging to two species, A.

[Isolation and partial characterization of poly-(a)+mRNA of soybean grown in the presence of gibberellic acid].

Poly(A)+mRNA was prepared by chromatography on the oligo (dT)-cellulose column from total RNA of epicotyls of soybean grown on the medium with gibberellic acid. Poly(A)+mRNA was prepared by the same method from control plants. Total RNA, poly-A and poly(A)+mRNAs were analyzed by electrophoresis on 1.

[Relationship between the nucleolar and karyoplasmic forms of RNA-polymerase in the nuclei of normal cells from different tissues and following hydrocortisone administration].

Correlation of the nucleolar and karyoplasmic forms of RNA-polymerase was studied in the cell nuclei of the brain, liver, kidneys and the spleen of rats under normal conditions and after hydrocortisone administration. Hydrocortisone was found to stimulate both the nucleolar and karyoplasmic RNA synthesis. In the nuclei of different tissues correlation of the nuclear and karyoplasmic forms of RNA-polymerase changed under the effect of the hormone unequally.
