title: [Biosynthesis of RNA in the nuclear structure of wilted cotton plant leaves].
abstract: The development of verticillate wilt in cotton plants is accompanied by an increase in the RNA-polymerase activity in isolated nuclear structures of cotton leaves at the latent stage of disease followed by its decrease when the plants develope inner signs of disease. The analysis of biosynthetic rates of nuclear RNA individual fractions showed that at the latent stage the biosyntheses of rRNAs and mRNAs in the nuclear structrues of the leaves are considerably enhanced. The development of inner signs of disease is accompanied by a disturbance of biosynthesis in the nucleus, primarily of mRNA. In the cells of wilted plants only 60% of the mRNA nucleotide sequences present in the controls are synthesized. Deficiency in matric cells for protein biosynthesis leads to further progress of the disease and to destruction of cells.
