Characterization and Classification of LMW-GS Genes at the <i>Glu-3</i> Locus of Bread Wheat.

ABSTRACT: Low Molecular Weight Glutenin Subunits (LMW-GS) proteins have great effects on the end-use quality of bread wheat and are difficult to differentiate directly. It is very important to characterize and classify LMW-GS genes systematically. In this paper, 692 complete Glu-3 gene sequences were retrieved from GenBank and were grouped based on their sequence characters and variations. Based on the characters of their N-terminal sequences, these genes were classified into two types, LMW-m and LMW-i, of which LMW-m genes were further classified into three sub-types based on their first amino acid (AA) (LMW-M, LMW-V and LMW-I). Based on the first seven or eight AA variations in the N-terminal sequence, LMW-GS Glu-3 genes were classified into 16 types, namely LMW-N1 to LMW-N16. Based
