Development of a high density map of qTGW6 and structures of candidate genes for qTGW6. (a) Graphical representation of F3:4:5 lines and a fine scale map of the target region on chromosome 6. Apo1 located between RM3430 and RM20562 might be allelic to qSPP6 detected in this study. White and black portions of the graph are homozygous Ilpumbyeo, homozygous Moroberekan, respectively and dotted regions are where crossing-over occurred. Genotypes of the 44 lines were double checked at F3 generation. The table to the right of the graphical genotypes indicates mean values of traits. Numbers followed by the same letter in each column are not significantly different at P = 0.05 based on Duncan’s multiple range test. & No. in ( ) indicate the number of F3 lines. P1: Ilpumbyeo, P2: IL28. (b) High density map of qTGW6 using two groups (D and J) and four markers. Four genes were predicted in the target 37.85-kb region. The arrowheads indicate the position of a single non-synonymous nucleotide substitution. (c) Structures of two genes, Loc_Os06g45550 and Loc_Os06g45560. Loc_Os06g45550 consists of five exons (black boxes) and four introns and Loc_Os06g45560 consists of 8 exons and 7 introns. Numbers on the structure of two genes show the position of non-synonymous nucleotide substitutions from the start codon.
