Quantitative trait locus mapping of deep rooting by linkage and association analysis in rice.

Lou Q, Chen L, Mei H, Wei H, Feng F, Wang P, Xia H, Li T, Luo L - J. Exp. Bot. (2015)

Bottom Line: Forty-eight significant SNPs of the RDR were identified and formed a clear peak on the short arm of chromosome 1 in a Manhattan plot.Seven of the nine candidate SNPs identified by association mapping were verified in two RDR extreme groups.The findings from this study will be beneficial to rice drought-resistance research and breeding.

Location of the major QTL on chromosome 2. The peak of the F curve indicates the putative position of this QTL. The grey horizontal line (F=6.4) indicates the threshold value for this RDR QTL mapping. Vertical lines in the linkage map indicate the genetic position of DNA markers (cM). Flanking markers of the QTL are shown on the bottom; numbers in parentheses beside DNA markers indicate their physical position base on the MSU6.0 Nipponbare genome from the RGAP database. Italic names indicate several known genes located in this region: IAA8 (LOC_OS02g49160), GS1 (LOC_Os02g50240), and PIN1 (LOC_Os02g50960). (This figure is available in colour at JXB online.)

Mentions: A total of six QTLs for RDR were identified from the three experiments, and were located on chromosomes 1, 2, 4, 7, and 10. The deep-rooting parental line IRAT109 provided the positive alleles for deep rooting in three QTLs. A major QTL flanked by RM6 and RM240 on chromosome 2 had the largest additive effect on RDR (Fig. 2). For future work, this QTL was named qRDR-2 (McCouch et al., 1997).
