dc.description.abstract <p>The <em>Phytophtora</em> root and stem rot is a serious disease in soybean. It is caused by the oomycete pathogen <em>Phytophthora sojae</em>. Growing <em>Phytophthora</em> resistant cultivars is the major method of controlling this disease. Resistance is race- or gene-specific; a single gene confers immunity against only a subset of the <em>P. sojae</em> isolates. Unfortunately, rapid evolution of new <em>Phytophthora sojae</em> virulent pathotypes limits the effectiveness of an <em>Rps</em> (“resistance to <em>Phytophthora sojae</em>”) gene to 8–15 years. The current study was designed to investigate the effectiveness of <em>Rps12</em> against a set of <em>P. sojae</em> isolates using recombinant inbred lines (RILs) that contain recombination break points in the <em>Rps12</em> region. Our study revealed a unique <em>Rps</em> gene linked to the <em>Rps12</em> locus. We named this novel gene as <em>Rps13</em> that confers resistance against <em>P. sojae</em> isolate V13, which is virulent to recombinants that contains <em>Rps12</em> but lack <em>Rps13</em>. The genetic distance between the two <em>Rps</em> genes is 4 cM. Our study revealed that two tightly linked functional <em>Rps</em> genes with distinct race-specificity provide broad-spectrum resistance in soybean. We report here the molecular markers for incorporating the broad-spectrum <em>Phytophthora</em> resistance conferred by the two <em>Rps</em> genes in commercial soybean cultivars.</p>
