Determination of the species of fungi of the genus Fusarium by molecular method

Currently, more than 10,000 species of fungi associated with plants have been found, and it is not surprising that fungal diseases cause a lot harm. Most the genus Fusarium are soil protrophs live on dead plant remains, in rhizosphere plants, surface roots. They rot roots, seeds, fruits, tubers, root crops. All forms fusariums progress at high temperatures humidity. The analysis literary sources experimental data allowed us to formulate purpose our research: “To analyze diversity from soil, table carrot depending ecological geographical zones growth.” As result, using PCR analysis, 13 samples attributed F. langsethiae were identified; 2 ochusrohim; 8 roae; sporotrichioides; 1 sample sulmorum, this was collected Rostov region Moscow region. It also revealed climatic conditions different leads change composition representatives R. Fusarium: varies significantly agro-climatic conditions. In wetter warmer (southern regions), specific culmorum, sporotrichiella, oxysporum dominate. heterosporum, nivale less common; graminearum lives residues, roots or zone, but practically does occur its pure form. Thus, direction promising for study Fusarium, since microorganism plants. advisable identify pathogen regions increas representativeness within further identification diverse mycelium, thereby creating scale mycelium.
