Five different Belinda cultivars grown in different location from China (IV). Mutated Belinda oat lines (V). Five Belinda plants treated with nitrogen fertilizers. An arrow showed in group III third lines is the nonallelic loci. b Diagrammatic representations of SDS-PAGE banding patterns of the respective allelic blocks which indicated (by arrows) in the figure of SDS-PAGE gel image. The lines numbered 1, 2, 3, 4, and 5 represent groups I, II, III, IV, and V, respectively, shown in (a). Each protein bands were numbered from A to I. Intensely stained bands are numbered using alphabet with high font size and mildly stained bands with alphabet having small font size
