[Isolation and purification of plant histones].

A fractionation pattern for isolation and identification of histones, allowing to obtain preparative amounts of individual histone fractions, is proposed. The obtained fractions were identified by their solubility, by differential staining and by electrophoresis. The fractionation resulted in all major histone fractions of wheat, rye, cotton, pea and calf thymus. The electrophoretic patterns of all plant histones were identical, differing only in their histone H1 contents. The histone fraction H1 was also found to be heterogeneous, which, with the exception of cotton H1 fraction, was more pronounced than in the case of calf thymus. The data obtained can be interpreted in terms of the functional role of histones in the genetic mechanism of plants and a possible use of individual fractions and components of histones for the study of phylogenetic relationships between the species.

[Seed proteins as markers in resolving the problems of genetic plant resources, selection and seed production].

The article discusses the main directions and prospects of usage of protein and DNA markers in decision applied and theoretical problems of plant genetic resources (gene banks), plant breeding, seed production and seed testing. The examples of usage of protein and DNA markers for solving important problems of applied botany, genetics and plant breeding were considered.

[Fine structure of the chromosomes of hexaploid wheat antipodal cells].

At the postendoreduplicative stage of chromosomes of antipodes are shown to be depolytenized and represented by solitary 0.1-0.3 micrometer chromonemas. Micropuffs and chromomer-like regions were found in the chromonemas. The chromonem puffing takes place independently of the nuclear membrane. A degradation of antipodal chromosomes begins in the zone of the nucleolus and spreads gradually over the whole nucleus. Later the cell is destructed but the nucleoli remain intact. Some of them are giant and vacuolized, others are similar to nucleoli of the usual low-ploidal nuclei.
