Ishimaru K. Plantphysiol 2003;133:1083-1090 ©2003 by American Society of Plant Biologists Frequency distributions of BILs for TGW in 1996, 1997, and 1998. Phenotypes of parents (rice cvs Nipponbare and Kasalath) are shown by arrows. Data are the means of six individual plants. Linkage map of BILs showing the putative location of QTLs for TGW in 1996, 1997, and 1998. N and K mean the direction of phenotypic effect caused by rice cvs Nipponbare and Kasalath, respectively. QTLs for other traits were reported by Ishimaru et al. (2001a, 2001b, 2001c). Chl, Chlorophyll. The mapping positions of SS and BEI were reported by Tanaka et al. (1995) and Nakamura et al. (1994), respectively. LOD score of QTL for TGW on chromosome 6 in 3 years. NILtgw6 contains the chromosomal region from rice cv Kasalath (black bar), containing the region of tgw6 (black line) in the background of rice cv Nipponbare. The distance (cM) from the short arm to each marker is shown in parentheses. The position of BEI was reported by Nakamura et al. (1994). Expression of genes related to starch synthesis—SS and BEI—in the –2 leaf sheath of rice cv Nipponbare (control) and NILtgw6. Total RNA (10 μg) from the –2 leaf sheath w
