Comparative genetic mapping ofArachis duranensisusing two different software programs on the same dataset. Genetic maps were constructed by MSTMap (left) using 1673 co-dominant markers and Joinmap 3.0 (right) using 1724 markers. Linkage group assignments, marker orders and genetic distances were highly consistent, except for the order among a few closely linked loci. Marker positions determined by Joinmap 3.0 are provided in Additional file 6.

Additional file 3:

Mapped markers with segregation distortion (p = 0.05) and their position on the map. Column A lists the marker positions on each chromosome, column B indicates marker name, column C is the chromosome number, columns D to H list the number of individuals in each genotype class, and columns J and K provide χ2 and P values, respectively.

Annotated loci mapped inArachis duranensis. Columns B to J include homologs identified in the Medicago (B-D), GenBank-NR (E-G) and Uniprot-Sprot (H- J) databases. Columns L to S include gene ontology (GO) terms identified in the three major GO categories: molecular function (N, O), biological process (P,Q) and cellular component (R,S).
