Estimation the functional activity of nucleolar organization chromosomes in Siberian spruce under different ecological conditions

Functional activity of nucleolar organization chromosomes have been studied in Siberian spruce growing in South Urals under different ecological conditions: in contrasting natural landscapes (high mountains, plains, river valleys and floodplains), in zones of natural geochemical anomalies and in areas with different levels of industrial pollution. The results provide evidence for enhancing the technogenic pollution and extreme environmental factors on functional activity of nucleolar organization chromosomes in Siberian spruce.
