Genetic mapping of circadian period QTL in the CvL and CoL RILs. QTL likelihood (LOD) maps across Arabidopsis chromosomes 1 and 5 in the CvL (A) and CoL (B) RILs. Chromosome numbers are indicated in the upper right corner of each graph. Names on the x-axis correspond to molecular markers. QTL were mapped independently at 12° (open diamonds), 22° (shaded diamonds), and 27° (solid diamonds). Dashed line represents 2.7 LOD significance threshold of P < 0.05 (as calculated from Van Ooijen 1999). Solid boxes on x-axis span the 2-LOD support interval of mapped QTL. Putative QTL designations are indicated in italics. Selected markers used as cofactors in mapping are identified above the x-axis with diamonds shown as open (12°), shaded (22°), and solid (27°) according to temperature.
