Recombination within theGli‐B1 Locus in Durum Wheat

摘要

AbstractRecombination within the closely linked genes encoding for omega and gamma gliadins at the complexGli‐B1 locus present on the short arm of chromosome 1B was detected in a durum‐wheat line (Triticum durum) from Iran. This recombinant differs from a previous one the authors detected in the durum‐wheat cultivar ‘Berillo’ since it shows the gamma gliadin component 45 associated with a triplet of omega components usually found linked with the allelic gamma gliadin 42. Analysis of low‐molecular‐weight glutenin subunits, encoded by genes at the complexGlu‐B3 locus associated with theGli‐B1 locus, showed the presence of the protein type designated LMW‐1 which is peculiar to durum‐wheat cultivars possessing
