20.500.12556/RUL-114186 Genetic diversity of the pine pathogen Lecanosticta acicola in Slovenia and Croatia Brown spot needle blight (BSNB), a disease of pine trees caused by the fungus Lecanosticta acicola, has been known in Slovenia since 2008 and in Croatia since 1975. Recent outbreaks in Slovenia prompted this study to compare L. acicola populations in these two neighbouring European countries. Sixty-nine isolates collected from three pine species (Pinus mugo, P. halepensis and P. nigra) were used to determine the phylogenetic relationships, genetic structure, and reproductive strategy of the pathogen. EF1-α sequences showed that Slovenian and Croatian isolates share a common ancestry with individuals from Central and Northern Europe. Population structure analysis revealed four distinct population clusters of L. acicola in these two countries, generally corresponding to their respective geographic location and host. An unequal ratio of mating types and a low overall genetic diversity in the population indicated a strong influence of asexual reproduction. Although some of the oldest recorded European occurrences of BSNB are from Croatia, this study provided no evidence that the population studied in Croatia was the source of the sampled outbreaks in Slovenia. Recent outbreaks of L. acicola in Slovenia are most likely due to introductions from other, yet to be identified, sources. brown spot needle blight elongation factor host preference mating type population genetics Pinus Lecanosticta acicola rjavenje borovih iglic paritveni tipi bori populacijska genetika true false true Angleški jezik Slovenski jezik Članek v reviji 2020-02-19 12:51:18 2020-02-19 12:51:19 2025-04-23 14:51:29 0000-00-00 00:00:00 2019 0 0 Str. 1120-1131 iss. 6 Vol. 68 2019 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 630*44 0032-0862 10.1111/ppa.13017 5349798 5661191 Plant_Pathology_-_2019_-_Sadikovic_-_Genetic_diversity_of_the_pine_pathogen_Lecanosticta_acicola_in_Slovenia_and_Croatia.pdf Plant_Pathology_-_2019_-_Sadikovic_-_Genetic_diversity_of_the_pine_pathogen_Lecanosticta_acicola_in_Slovenia_and_Croatia.pdf 1 9258A1881F0FA527EA44B5C5913789BB c91546b464fc9ba3695d7f2ab4272b273660cff59d904cf129e805ecf0a65a42 44e310e6-1acb-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=208531 https://bsppjournals.onlinelibrary.wiley.com/doi/10.1111/ppa.13017 0 435e6894-1b7c-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209149 Biotehniška fakulteta 0 0 0
