Genetic Analysis of Glutamate-Oxaloacetate Transaminase Isozymes in Wild Species in Section Cepa of Allium.

Genetic analysis of phosphoglucoisomerase isozymes in cultivated and wild species of section Cepa in Allium

“…This 199 indicates that a translocation including the gene locus Got-2 did not occur between non-homologous chromosomes in both species during speciation and subsequent evolution . In the wild species, the genetic systems of three isozymes, GDH (Shigyo et al ., 1995b), GOT (Tashiro et al ., 1995) and PGI (the present study), have thus far been established . Further studies to determine the chromosomal locations of several isozyme gene loci including Gdh-1, Got-1, Got-2 and Pgi-1 in the wild species will elucidate the chromosomal evolution and process of speciation in section Cepa .…”

Isozymes of the wild species were only studied on glutamate dehydrogenase (GDH) and glutamate-oxaloacetate transaminase (GOT) (Shigyo et al ., 1995b ;Tashiro et al ., 1995) . In the present study, phosphoglucoisomerase (PGI) isozyme analysis was performed to establish the genetic system in both the cultivated and wild species of section Cepa .…”
