Abstract

Šipak je u Hrvatskoj biljna vrsta koja je relativno slabo istražena. Podložan je napadu mnogih patogena, od toga u najvećem broju fitopatogenih gljivama. Tijekom 2019. godine u Dalmaciji je uočeno sušenje šipaka što je prema simptomima, uočenima u prethodnim istraživanjima, upućivalo na citosporiozno sušenje uzrokovano fitopatogenom vrstom Cytospora punicae. Iako se vrsta Cytospora punicae smatra patogenom slabosti ona može uzrokovati i ozbiljna oštećenja i propadanja cijele biljke. Izolirane... More gljive identificirane su provizorno prema morfološkim obilježjima kolonija i konidija na PDA. Reprezentativni izolati su dodatno istraženi analizom DNA sekvenci molekularnog markera ITS primjenom metode PCR. Dobivene ITS sekvence su uspoređene s odgovarajućim sekvencama izolata C. punicae iz baze podataka GenBank primjenom bioinformatičkog programa BLAST, s za filogenetsku analizu je korištena metoda Maximum Likelihood. Svi analizirani izolati iz ovog istraživanja su identificirani kao vrsta C. punciae. Less

Abstract (english)

In Croatia, pomegranate is a plant species that is relatively poorly researched. It is susceptible to attack by many pathogens, of which in the largest number of phytopathogenic fungi. During 2019, drying of pomegranates was observed in Dalmatia, which according to the symptoms, observed in previous studies, indicated cytosporic drying caused by the phytopathogenic species Cytospora punicae. Although Cytospora punicae is considered a pathogen of weakness, it can also cause severe damage and... More decay of entire plants. Isolated fungi of identification are provisional according to the morphological characteristics of colonies and conidia on PDA. Representative isolates were further investigated by DNA sequence analysis of the ITS molecular market using PCR methods. The obtained ITS sequences were compared with the corresponding sequences of C. punicae isolates from the GenBank data base using the BLAST bioinformatics program and the Maximum Likelihood method was used for phylogenetic analysis. All analyzed isolates from this study were identified as C. punicae species. Less
