Identification of birch mushrooms with anomalies of morphological attributes and excess of 137Cs maintenance in fruit bodies by the method of rDNA sites restriction analysis
The article analyses the molecular weights estimation of fragments ITS1-5,8S-ITS2 and IGS1 rDNA and its RFLP for the species of Leccinum genus from the East-European part of Russia. For the IGS1 such data are received for the first time. On the basis of the rDNA fragments analysis it is established that birch mushrooms with anomalies of morphological attributes and excess of total beta-activity in fruit bodies owing to accumulation 137Cs represent Leccinum holopus, the Birch mushroom marsh. For the first time among the highest basidiomycetes funji the biomonitor changing morphological attributes at accumulation of 137Cs in fruit bodies is found out.
