Detekce patogenů lilku bramboru přežívajících v půdě
Valkovičová, Nikola
The bachelor's thesis dealt with the detection and sequencing of soil-borne pathogens of pota-to eggplant. The focus is mainly on pathogens of the genus Fusarium. These pathogens cause such potato rot, which forms white mycelium coatings and subsequently mummifies, that it is not suitable for consumption and the yield is reduced. One of the most accurate methods was chosen for the detection of pathogens – PCR. For the detection of Fusarium pathogens from other potato tubers, conventional PCR was used with non-specific primers ITS4 and ITS5 annealing to the region between the genes that code for ITS4 and ITS5 RNA. For the detection of pathogens from the soil, real–time PCR was chosen with primers ITS1F and AFP346 sitting in the region that encode nRNA and space bars ITS1 and ITS2. The tested soil was artificially inoculated with an unknown isolate of the genus Fusarium obtained from a potato tuber and a collection isolate of Fusarium solani var. coeruleum. Se-quencing confirmed infection of the potato tuber with Fusarium culmorum, clarifying the dif-ficulty of quantification.
