Identification of chromosomal regions that exhibit evidence of selection. Identification of chromosomal regions that exhibit evidence of selection. Allele frequencies were compared between 177 converted tropical lines and 40 cultivars. A 99.5% fixation index cutoff is indicated by horizontal dashed lines. Vertical dashed lines designate the positions of 35 TASs. TASs located within divergent regions are indicated in red. Two TASs on chromosome 3 at 58,920,501 and 58,994,806 bp are represented by a single red dashed line. Candidate genes are labeled. Gray shading on chromosomes 6, 7, and 9 indicates genomic regions identified by Thurber et al. (2013) carrying maturity and plant height genes introduced in the SCP. Yan Zhou et al.
