Searching for genes determining the APR phenotype in rye.

ABSTRACT:

Background

Adult-plant resistance (APR) is a type of genetic resistance of cereals against a range of disease-causing pathogens including leaf rust (LR). In rye, APR to LR although known, is poorly understood, especially at the molecular level. Recently, numerous variants of genes encoding ATP-binding cassette (ABC) and sugar transporters, have been identified in the rye transcriptome. In these two pools of genes, we decided to find genes determining APR using both nucleotide and amino acid sequence similarity to the Lr34 and Lr67 genes carrying the APR to LR in wheat as the main selection criterion and as an additional criterion - expression profiles of chosen variants in seedlings infected with LR.

Results
