Abstract
During the past few years, symptoms of garlic clove rot have appeared in storage facilities at different localities in Serbia. Thirteen fungal isolates were isolated from samples of decayed garlic cloves (Allium sativum L.). Based on the colony and fungal morphology, isolated fungi were tentatively identified as F. proliferatum. Pathogenicity of 13 F. proliferatum strains were confirmed by inoculating garlic cloves of Allium sativum (spring cv. Labud, Sedef; winter cv. Bosut, Ranko) and Allium ampeloprasum (cv. Biser). Isolate JBL532 was classified as the most aggressive, while isolate B3 was the least pathogenic. To confirm morphological identification of 13 Fusarium isolates, amplification of TEF-1α gene was performed using polymerase chain reaction (PCR) with the primer pair: EF1 and EF2. All isolates were cryopreserved at -80°C and deposited in the NCBI GenBank.
Tokom proteklih godina u skladištima na različitim lokalitetima u Srbiji pojavili su se simptomi truleži i popadanja belog luka (Allium sativum L.). Izolacijom je dobijeno 13 izolata gljiva roda Fusarium koji su na osnovu morfoloških karakteristika identifikovani kao F. proliferatum. Patogenost izolata je potvrđena inokulacijom različitih genotipova belog luka Allium sativum (prolećne sorte Labud, Sedef, jesenje sorte Bosut, Ranko) i Allium ampeloprasum (sorta Biser). Na osnovu ocene patogenosti, izolat JBL532 se izdvojio kao najagresivniji, dok se izolat B3 pokazao kao najmanje patogen. Morfološka identifikacija potvrđena je amplifikacijom TEF-1α gena, korišćenjem prajmera EF1 i EF2. Svi izolati se čuvaju na -80°C i deponovani su u NCBI bazu gde su im dodeljeni jedinstveni pristupni brojevi.
