Chromosome location of two isozyme loci in Lolium perenne using primary trisomics

E. J. Lewis, M. W. Humphreys, M. P. Caton

Research output: Contribution to journalArticlepeer-review


Primary trisomics were used to locate the structural loci coding for particular forms of the dimeric enzymes phosphoglucoisomerase and glutamate oxaloacetate transaminase in Lolium perenne. The polymorphy of these loci enabled triallelic trisomics to be produced. Each locus could thus be directly assigned to a particular chromosome without the need to examine segregant progeny. The loci for GOT/3 and PGI/2 were found to be located on chromosomes 2 and 6 respectively.
