DNA fingerprints to determine self-fertilization (homothallism) or outcrossing (heterothallism) in Antarctic lichen

GB/NERC/BAS/PDC/00621

Abstract:
The majority of Antarctic lichens produce sexual organs, and in many species sexual ascospores appear to be the only reproductive propagule. However, it is unknown whether sexual reproduction involves selfing (homothallism) or outcrossing (heterothallism). To investigate this issue we have established axenic cultures of sexual progeny in order to generate DNA fingerprints and thereby determine the breeding system.
