title: Linkage mapping of prolamin and isozyme genes on the 1S(l) chromosome of Aegilops longissima.
abstract: The storage proteins and isozymes of two accessions of Aegilops longissima, and the F2 progeny from the cross between them, were analyzed. Six loci were identified on the 1S(l) chromosome: Glu-S (l) 1 (coding for HMW subunits of glutenin), Gpi-S (l) 1 (coding for a Gpi isozyme), Glu-S (l) 3 (coding for LMW subunits of glutenin), Gli-S (l) 1 (coding for gliadins) and two, so far, not described new loci Gli-S (l) 4 and Gli-S (l) 5. The Gli-S (l) 4 locus codes for a ω-gliadin and the Gli-S (l) 5 codes for a gliadin with mobility in the β-region. The genetical distances found between the six loci allowed the establishment of the following gene order on the 1S(l) chromosome: Glu-S (l) 1 -centromere -Gpi-S (l) 1 - Gli-S (l) 4 - Gli-S (l) 3 - Gli-S (l) 1 -Gli-S (l) 5.
