Novel Genetic Diversity and Geographic Structures of Aspergillus fumigatus (Order Eurotiales, Family Aspergillaceae) in the Karst Regions of Guizhou, China.

ABSTRACT: Aspergillus fumigatus is the primary pathogen causing aspergillosis. Recent molecular population genetic studies have demonstrated that A. fumigatus exhibits high local genetic diversity, with evidence for limited differentiation among geographic populations. However, research on the impacts of geomorphological factors on shaping the population genetic diversity patterns of this species remains scarce. In this study, large-scale sampling and in-depth population genetic analysis were performed on soil-derived A. fumigatus from Guizhou Province, a representative karst landscape in southern China. This area is dominated by plateaus and mountains (accounting for 92.5% of the total area) and represents a classic example of conical karst landscapes. A total of 206 A. fumi
