Co-dispersal of symbionts in the lichen Cladonia stellaris inferred from genomic data. Fungal Ecology, 60, 101165. https://doi.org/10.1016/j.funeco.2022.1011651754-504810.1016/j.funeco.2022.101165https://hdl.handle.net/20.500.14352/123803This research was conducted with financial support from the program Sentinel North financed by the Canada First Research Excellence Fund (CFREF); the CRNSG- RGPIN/05967–2016 and the Canadian Foundation for Innovation (projects 36781, 39135). RP-B was funded by Gastby Foundation under the excellence researcher program.We tested the congruence in dispersal patterns of the two main symbionts of the lichen Cladonia stellaris using genotyping-by-sequencing data. Based on 122 samples from eastern Canada, we recovered more than 21000 loci from the photobiont of C. stellaris. We described the population structure and estimate genetic diversity of the photobiont and identified the factors that contribute to explain genetic variation in both lichen partners. We also determined the identity of the dominant photobiont associated to C. stellaris using two molecular markers. Our results showed that C. stellaris is associated with Asterochloris glomerata, A. irregularis, and A. pseudoirregularis. Congruence in the genetic structure of photobiont and mycobiont were confirmed, suggesting co-dispersal of thallus fragments of C. stellaris. Genetic diversity of each symbiont was the factor that explained most of the genetic variation of the other symbiont, whereas geographical location and bioclimatic region seemed to have small or null explanatory power.engjournal article1878-0083https://doi.org/10.1016/j.funeco.2022.101165https://www.sciencedirect.com/science/article/pii/S1754504822000265restricted access574.582.4574.9575582.29574Asexual reproductionAsterochlorisCongruenceDispersalEastern CanadaGenotyping-by-sequencingReindeer lichenLong-distance dispersalSpatial genetic structureEcología (Biología)Botánica (Biología)Genética2417.13 Ecología Vegetal2417 Biología Vegetal (Botánica)2409 Genética
