摘要：

Oligo-GATA containing probes reveal DNA fingerprinting patterns in DNA of Microseris pygmaea after restriction enzyme digestion. There are only a few major restriction fragments. These are longer than 2 kb, and they differ completely among plants from different populations, among most members of a single local inbreeding population, and even among some parent and offspring plants. In the F2 of an interpopulation hybrid, major fingerprint bands could be assigned to 2 unlinked loci by 3:1 and 1:2:1 segregations respectively, one further band segregated roughly 1:1, one band appeared irregularly. The hypervariability of the GATA-fingerprint loci contrasts with a low variability of other genetic markers in M. pygmaea and with a more complex but less variable GATA-fingerprint pattern in related species.
