An isoenzyme survey of several taxa within the genus Lotus was undertaken to provide markers for genetic research and to test hypotheses concerning the phylogenetic origin of Lotus corniculatus L. A preliminary study identified seven enzyme systems PGI, TPI, PGM, MDH, IDH, 6-PGDH and ME, that produced consistent clear phenotypes in L. uliginosus Schkuhr. Variation in phenotype with tissue type and stage of development suggested the presence of several isozyme zones in the phenotypes. Enzyme phenotype was constant for shoot tissue of plants older than six weeks. A second study examined recombination and segregation of isoenzyme phenotypes in interspecific hybrids, allo- and autopolyploids, and in L. corniculatus. Duplication and quadruplication of pgi2 loci in hybrids, amphidiploids, and in L. corniculatus was used as evidence that the latter is a segmental allotetraploid. A third study surveyed the occurrence of various isoenzyme alleles in L. alpinus Schleich., L. japonicus (Regel) Larsen, L. tenuis Waldst. & Kit., L. uliginosus and L. corniculatus. Lotus uliginosus had unique distinct alleles for several enzymes that did not occur in the other species. This evidence argues against the involvement of L. uliginosus in the origin of L. corniculatus.

The isolation and purification of triosephosphate isomerase from humanerythrocytes, cardiac and skeletal muscle, liver, and brain has been described. Subsequent isolation and characterization of three isozymes from three tissues was effected.
