Carbohydrates of cultivated varieties ofAlthea rosea

The polysaccharides of three cultivated varieties ofAlthea rosea have been investigated. The amounts of water-soluble polysaccharides and pectin substances in various organs of the plant have been determined. It has been shown that the maximum amount of water-soluble polysaccharides and pectin substances is present in the flowers. Their monosaccharide compositions have been studied. The physicochemical characteristics of the pectin substances are given.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Republic of Uzbekistan, Tashkent. A.

Phosphorylation of cottonplant proteins under the action of protein kinase inhibitors and activators

The occurrence of Ca²⁺-, Ca²⁺-phospholipid-, Ca²⁺-calmodulin-, and cAMP-dependent phosphorylation has been shown with the aid of protein kinase activators and inhibitors and by electrophoresis and autoradiography. Specific substrates have been revealed and it has been demonstrated that the pathways of the realization of the action of cAMP-dependent and Ca²⁺-calmodulin-dependent protein kinases may intersect.A.

Influence of defoliating agents on the level of some secondary metabolites in cotton-plant leaves

The change in the composition of the secondary metabolites (SMs) of cotton-plant leaves under the influence of two modifications of defoliating agents in the period of leaf fall has been studied. It has been shown that, in contrast to the dynamics of the SMs in genetic deciduous lines, up to the period of leaf-fall the amount of free sterols in the petioles decreases, while in the leaf blades it remains unchanged. In experiments with cotyledons, the opposite effect was observed. In all cases, the amount of polyprenols decreased substantially.Institute of Chemistry of Plant Substances, Uzbekistan Republic Academy of Sciences, Tashkent.
