Figure 3. SNP (G to A) depicting the missense non-synonymous amino acid substitution [Glutamic acid (GAG) to Lysine (AAG)] in an OsMED4_2 gene differentiated the low (8–12 g) and high (23–27 g) grain weight parental accessions and representative homozygous individuals of a F₄ mapping population (IR 64 × Sonasal).

The MED gene sequence region-carrying a non-synonymous SNP allelic variant is highlighted with a dotted box.
