Abstract

Methods for conveying soybean rust (SBR) resistance into non-resistant soybean germplasm are provided. In some embodiments, the methods include introgressing SBR resistance into a non-resistant soybean using one or more nucleic acid markers for marker-assisted breeding among soybean lines to be used in a soybean breeding program, wherein the markers are linked to and / or associated with SBR resistance. Also provided are single nucleotide polymorphisms (SNPs) associated with resistance to SBR; soybean plants, seeds, and tissue cultures produced by any of the disclosed methods; seed produced by the disclosed soybean plants; and compositions including amplification primer pairs capable of initiating DNA polymerization by a DNA polymerase on soybean nucleic acid templates to generate soybean marker amplicons.

Description

TECHNICAL FIELDThe presently disclosed subject matter relates to markers associated with soybean rust (SBR) resistance and methods of use therefor. More particularly, the presently disclosed subject matter relates to screening soybean lines for resistance to SBR and for producing soybean lines with improved resistance to SBR, the methods involving genetic marker analysis.BACKGROUNDPlant pathogens are known to cause massive damage to important crops, resulting in significant agricultural losses with widespread consequences for both the food supply and other industries that rely on plant materials. As such, there is a long felt need to reduce the incidence and / or impact of agricultural pests on crop production.Soybean rust (SBR), which is caused by the obligate fungal pathogen Phakopsora pachyrhizi H. Sydow & Sydow, was first reported in Japan in 1902. By 1934, the pathogen was reported in several other Asian countries and in Australia. More recently, P. pachyrhizi infection has been ...
