Abstract
Značajni čimbenici u evolucijskom razvoju fitopatogene gljive Ophiostoma novo-ulmi, uzročnika holandske bolesti brijesta, su hibridizacija i prijenos gena od srodne vrste O. ulmi. Spolno razmnožavanje, koje značajno doprinosi povećanju varijabilnosti O. novo-ulmi, moguće je samo između različitih tipova parenja, označenih kao MAT-1 i MAT-2, što je određeno različitim idiomorfima na MAT lokusu. Pojava MAT-1 tipa u originalno klonalnim populacijama O. novo-ulmi MAT-2 tipa dogodila se primarno putem introgresije gena vrste O. ulmi u genom O. novo-ulmi. U ovom radu analizirani su izolati O. novo-ulmi uzorkovani 2012. i 2021. godine na lokalitetima Jastrebarsko i Nova Kapela. Cilj je bio analizirati regiju uz 3' kraj MAT lokusa te istražiti jesu li oba MAT tipa prisutna u analiziranim populacijama. Sekvenciranje regije uz 3' kraj MAT lokusa izolata O. novo-ulmi ukazalo je na introgresiju MAT lokusa kod dijela analiziranih izolata. Dokazana su oba tipa spolne kompatibilnosti (MAT-1 i MAT-2) što ukazuje na postojanje potencijala za spolno razmnožavanje. Do značajnijeg širenja MAT-1 izolata na istraženim lokalitetima na području Hrvatske došlo je nakon 2012. godine.
Abstract (english)
Significant factors in the evolutionary development of the phytopathogenic fungus Ophiostoma novoulmi, the causative agent of Dutch elm disease, are hybridization and gene transfer from the related species O. ulmi. Sexual reproduction, which significantly increases the variability of O. novo-ulmi, is possible only between different mating types, designated as MAT-1 and MAT-2, which are determined by different idiomorphs at the MAT locus. The appearance of MAT-1 type in originally clonal populations of O. novo-ulmi of MAT-2 type occurred primarily through introgression from O. ulmi. In this study, O. novo-ulmi isolates sampled in 2012 and 2021 at the sites Jastrebarsko and Nova Kapela were analyzed. The aim was to analyze 3’ flanking region of the MAT locus and to investigate whether both MAT types are present in the analyzed populations. By sequencing 3’ flanking region of the MAT locus, introgression of MAT locus was proven for the same of the analyzed isolates. The presence of both mating types has also been proven, which indicates the potential for the sexual reproduction of the pathogen. A significant spread of MAT-1 isolates at investigated sites occurred after 2012.
