Abstract
Territorial distribution of four alleles of one histone H1 subtype was investigated in the natural population of a leguminous plant Vicia unijuga A.Br, inhabiting an area of about 35 km2, including Novosibirsk Academy Town (Akademgorodok). Histone H1 was isolated from pools of 100 plants (one leaflet per plant) collected from points of approximately 100 m2. The proportion of alleles estimated for 119 different points revealed a radial cline. The frequency of an allele that predominates everywhere in the circumference decreases towards the historical centre of Akademgorodok, while two other alleles show the opposite tendency. The observed pattern of territorial distribution was likely due to some man-caused factor (presumably insecticide treatment) that has been acting for a period of time not exceeding the 25 years of Akademgorodok's existence. Key words: histone H1 polymorphism, Vicia unijuga A.Br., natural selection in an urbanized area.
