Abstract
Mapping genes in biochemical pathways allow study of the genomic organization of pathways and geneic relationships within these pathways. Additionally, molecular markers located within the boundaries of a specific gene sequence represent important marker assisted selection resources. We report map locations of two geneic markers from the purine synthesis pathway in soybean (Glycine max (L. merr.)), utilizing a 90 plant F(2) population created from the cross of "DT97-4290" x "DS97-84-1". Primers were designed based on sequences from annotated soybean complimentary DNA. A polymorphic, co-dominant, sequence-characterized amplified region marker was created for hypoxanthine phosphoribosyl transferase (EC 2.4.2.8). Linkage analysis placed this gene on linkage group (LG) O. In addition, a single-nucleotide polymorphism (SNP) marker was developed for a urate oxidase gene (EC 1.7.3.3). Linkage analysis of the SNP placed the urate oxidase gene on LG I. For both genes, amplicon sequence data confirmed the identification of the respective gene. Mapping these genes represents the first step in understanding the genomic organization of the purine biochemical pathway in soybean.
