Chromosomal locations of five isozyme gene loci (Lap-1, Got-1, 6-Pgdh-2, Adh-1 and Gdh-1) in shallot (Allium cepa L. Aggregatum group).

Abstract

The chromosomal locations of isozyme gene loci encoding leucine aminopeptidase (LAP), glutamate-oxaloacetate transaminase (GOT), 6-phosphogluconate dehydrogenase (6-PGDH), alcohol dehydrogenase (ADH) and glutamate dehydrogenase (GDH) were investigated in shallot (Allium cepa L. Aggregatum group). The alien monosomic addition lines of A. fistulosum L. with the extra chromosomes (1A, 2A, 6A, 8A and other unidentified chromosomes) from A. cepa Aggregatum group were used for plant materials. The results revealed that the five gene loci, Lap-1, Got-1, 6-Pgdh-2, Adh-1 and Gdh-1, were located on the chromosomes 1A, 2A, 2A, 6A and 8A, respectively.
