The interaction between DEP1 and OsMADS1 regulates grain size and yield potential of rice. a Grain morphology. Scale bar: 5 mm. b QTL mapping for grain length and grain yield. c The positional cloning of qLGY3. The candidate region was mapped to a ~ 8.9 Kbp genomic DNA region lying between markers XP22 and XP23. The numbers below the line indicate the number of recombinants recovered between qLGY3 and markers. d Allelic variations of OsMADS1 between RD23 and L-204. In the schematic illustration of OsMADS1 functional domains, M represents the MADS domain, I represents the intervening domain, K represents the keratin-like domain, and C represents the C-terminal domain. e The gross morphology of NIL plants. Scale bar: 15 cm. f Grain size and shape. Scale bar: 5 mm. g–n A field-based comparison of the WYJ7-LGY3-dep1-1 and WYJ7-lgy3-dep1-1 plants: g Plant height; h Heading date; i The number of tillers per plant; j The number of grains per panicle; k Grain length; l Grain width; m 1,000-grain weight; and n The overall grain yield per plant. All phenotypic data were measured from the paddy-grown NIL plants grown under normal cultivation conditions. Data shown as mean ± s.e.m. (n = 288). Student’s t-test was used to generate the P values
