[High level of polymorphism and autotetraploid origin of rare endemic species of Fabaceae, Oxytropis chankaensis Jurtz., inferred from allozyme data].

Abstract excerpt

Using starch electrophoresis, we examined 19 enzyme systems presumably controlled by 35 loci in the rare endemic tetraploid species Oxytropis chankaensis Jurtz. (Fabaceae). Electrophoretic patterns and their genetic interpretation are presented. The isozyme data suggest tetrasomic inheritance in O. chankaensis. Three or four alleles at a particular locus were found in a number of individual plants, which indicate...
