We developed bulked segregant analysis as a method for rapidly identifying markers linked
to any specific gene or genomic region. Two bulked DNA samples are generated from a …

Sequence characterized amplified regions (SCARs) were derived from eight random
amplified polymorphic DNA (RAPD) markers linked to disease resistance genes in lettuce …

Genes cloned from diverse plants for resistance to different pathogens have sequence
similarities in domains presumably involved in pathogen recognition and signal transduction …

ABSTRACT A detailed linkage map of lettuce was constructed using 53 genetic markers
including 41 restriction fragment length polymorphism (RFLP) loci, five downy mildew …

For many years, the principles of genetics have been applied to crop variety improvement
with great success. Severa1 crop species, notably corn, wheat, and tomato, have been used …

Two sets of overlapping experiments were conducted to examine recombination and
spontaneous mutation events within clusters of resistance genes in lettuce. Multiple …

Maize and tomato cDNA clones have been hybridized in Southern blotting experiments to
plant genomic DNA prepared from different lines to detect restriction fragment …

The model plant Arabidopsis thaliana exhibits extensive natural variation in resistance to
parasites. Immunity is often conferred by resistance (R) genes that permit recognition of …

Oligonucleotide primers, designed to conserved regions of nucleotide binding site (NBS)
motifs within previously cloned pathogen resistance genes, were used to amplify resistance …

Until relatively recently, knowledge of plant resistance to pathogens has resulted primarily
from research associated with the selective breeding of crop species. Although resistance is …
