Dissection of two soybean QTL conferring partial resistance to Phytophthora sojae through sequence and gene expression analysis.

ABSTRACT:

Background

Phytophthora sojae is the primary pathogen of soybeans that are grown on poorly drained soils. Race-specific resistance to P. sojae in soybean is gene-for-gene, although in many areas of the US and worldwide there are populations that have adapted to the most commonly deployed resistance to P. sojae ( Rps) genes. Hence, this system has received increased attention towards identifying mechanisms and molecular markers associated with partial resistance to this pathogen. Several quantitative trait loci (QTL) have been identified in the soybean cultivar 'Conrad' that contributes to the expression of partial resistance to multiple P. sojae isolates.

Results

In this study, two of the Conrad QTL on chromosome 19 were dissected through sequence and expression analysis of
