[Inheritance of differences in organ trichome formation in Arabidopsis thaliana (L.) Heynh. plants].

It was determined that, according to the character "hairiness of rosette leaves", gl1-1 allele in homozygote state suppresses action of dis2-1 allele (dis2-1 < gl1-1), therefore F2 segregation is identified in a typical for recessive epistasis ratio of 9:3:4. Inheritance of differences in hairiness of stem leaves corresponds to the Mendel scheme of segregation (9:3:3:1), which is typical for dihybrids. Hairiness is absent on stems of triple recessive for dis2-1, er-1, gl1-1 plants, and segregation in F2 is observed in the ratio of 9:3:4.

[Perspective of genetic improvement of inflorescences structure in oil crops of Brassicaceae family].

The theoretical substantiation and new scientific decision of ability to genetic construction of agriculturally valuable inflorescence structure in oil crops of Brassicaceae family are proposed on the examples of A. thaliana genes AP1, BP1 and TFL1. New types of plants are more suitable to machine seed harvesting as a result of decreasing non-simultaneous ripeness of seeds within inflorescences.
