No evidence of reproductive character displacement between two sister fungal species causing anther smut disease in Silene.

摘要: Reproductive isolating mechanisms that are stronger for sympatric populations than allopatric of a given species pair indicative reproductive character displacement, is, selection increased barriers to avoid the costly production hybrid offspring. Evidence displacement in nature remains equivocal and requires further experimental studies. The genus Microbotryum includes anther‐smut fungi, which castrate pathogens specialized on different plants Caryophyllaceae serve as excellent models studying speciation. lychnidis‐dioicae silenes‐dioicae sister show no assortative mating relatively high viability and, yet, display lack gene flow natural populations. We wanted test whether these apparently contradictory results could be explained by displacement. first confirmed absence detectable between ...
