Introgression of crown rust (Puccinia coronata) resistance from meadow fescue (Festuca pratensis) into Italian ryegrass (Lolium multiflorum): genetic mapping and identification of associated molecular markers
Plant Pathology 55 (1), 62-67
Abstract: Crown rust (Puccinia coronata) resistance (CRres), which had been introgressed from meadow fescue (Festuca pratensis) into the Italian ryegrass (Lolium multiflorum) background, was genetically mapped with amplified fragment length polymorphism (AFLP) and sequence tagged site (STS) markers to a terminal segment of chromosome 5. Comparative mapping had previously shown that this region of the Lolium/Festuca genome has a degree of conserved genetic synteny with chromosomes 11 and 12 of rice. Sequences from rice chromosome 12 were used as templates for identifying further STS markers that cosegregated with CRres. The relative genomic positions of molecular markers associated with CRres in L. multiflorum, L. perenne, F. pratensis and oats is discussed, along with their relationships to physical positions on rice chromosomes C11 and C12.
