Phenotypic Distribution of KRN.
(A) The total number of individuals with a given KRN value are indicated on the x-axis. Only the top ear from each plant was scored. (B) Boxplot representation of the data shown in (A).
Fig 2.
RCNILs sorted by KRN phenotype.
Left panel presents the genetic maps of 68 RCNILs for the interval on the long arm of chromosome 1 containing KRN1.4. It shows the physical positions of the 18 genetic markers used in this study (S1 Table) based on the RefGen_v2 assembly. White bars indicate DNA homozygous for the maize W22 allele, black bars DNA homozygous for the teosinte allele, and gray boxes the regions within which the recombination break points are located. Least squared means values for KRN with standard error bars for each line are shown in the right panel. Blue bars represent KRN of RCNILs derived from the MR0194 population and pink bars KRN of RCNILS derived from the MR0579 population. Red lines delineate the interval with the best fit of genotype and phenotype.

Molecular markers used in this study are indicated by vertical lines above the x-axis. Marker coordinates are given in S1 Table. Chromosomal positions in megabases are based on B73 RefGen_v2. Dashed line indicates the 5% significance threshold level. Vertical gray bar indicates the 1.5-LOD confidence interval.

Genes in the 1.5-LOD confidence interval for KRN1.4.
Black boxes represent genes described in the 1.5-LOD support interval for KRN1.4. The red box indicates the position of the indeterminate spikelet 1 (ids1) gene. Arrows indicate transcriptional direction.
