Abstract | BACKGROUND: RESULTS: Using available EST resources for a single hexaploid oat cultivar, the spectrum of avenin and globulin sequences are described for the gene coding regions and the derived protein sequences. The nine unique avenin sequences are suggested to be divided into 3-4 distinct subclasses distributed in the hexaploid genome. The globulins from the same germplasm include 24 distinct sequences. Variation in globulin size results mainly from a glutamine-rich domain, similar to as in the avenins, and to variation in the C-terminal sequence domain. Two globulin genes have premature stop codons that shorten the resulting polypeptides by 9 and 17 amino acids, and eight of the globulin sequences form a branch of the globulins not previously reported. CONCLUSIONS: A more complete description of the major oat seed proteins should allow a more thorough analysis of their contributions to those oat seed characteristics related to nutritional value, evolutionary history, and celiac disease association.
