Technical Abstract: Glycinin is the most prevalent seed storage protein in soybean, and is important because it is a major contributor to the nutritional quality of foods and feeds generated from this agronomically important crop. As part of a continuing study about the genes that control the synthesis and assembly of glycinin, the nucleotide sequence of a defective glycinin pseudogene (Gy6) is reported. The sequence is part of the original data that backs up a description of the gene and its location in the soybean genome given in a manuscript entitled "Genomic organization of glycinin genes in soybean". The information will be most useful to geneticists and plant cell biologists interested in soybean.
