Summary
One and two-dimensional sodium dodecyl sulphate Polyacrylamide gel electrophoretic techniques have been used to follow the inheritance of legumin and convicilin subunits in crosses of various pea lines. The major legumin acidic subunits behaved as products of a single Mendelian gene with at least five different possible alleles. Independent segregation of a minor “big” legumin acidic subunit and the acidic and basic subunits of “small” legumin were observed, suggesting that while the main legumin subunits are produced from a set of closely linked genes at a single locus, further weakly expressed legumin genes are present at other loci. Convicilin subunits behaved as the products of a single Mendelian gene with at least three allelic forms. Genetic analysis of F2 seeds and plants from crosses of pea lines was used to map the major legumin gene (Lg-1) to a locus near the r-tl segment of chromosome 7 and the convicilin gene (Cvc) to a locus between s and k on chromosome 2.
