The percentage of total genetic var

The percentage of total genetic variation among populations (FST)
was 9.36% for ISSR and 17.08% for SRAP, which is low for the
mean FST values (25%) found for 52 endemic plants [25]. Like other
Magnolias, M. wufengensis is a long-living species and the accessions
in this study are all adult trees, at least 30 to 50 years old, located in
natural woods and proved by local residents. For rare species, it is of
greater concern when gene flow estimates are high since they may
reflect previous intermingling of populations and should not be
interpreted as indicating the present state of population isolation [27].
In our study, the high estimated Nm values between populations, plus
high levels of genetic diversity within geographical regions, suggest a
likely migrant-pool migratory model [28], which describes a migratory
pattern with colonists recruited from a random sample of previously
existing populations. This model is usually associated with glaciation
