Arabidopsis ecotypes, Columbia (Col) and Landsberg erecta (Ler), differ in their capacity to regenerate shoots in culture, as do many other cultivars and varieties of the same plant species. Recombinant inbred (RI) lines derived from a cross of Col x Ler were scored for shoot regeneration, and the Arabidopsis genome was scanned using composite interval mapping for loci associated with shoot regeneration. Three QTL were identifieda major one on chromosome 5 in which the Col parent contributed the superior allele and two minor QTL on chromosomes 1 and 4 in which the Ler parent contributed the superior alleles. The RI lines were binned into genotypic pools to isolate the effects of the major QTL on chromosome 5 while holding the minor QTL constant. To identify genes with expression levels that are associated with the allelic state of the major QTL on chromosome 5, oligonucleotide array expression patterns for genes in the LLC pool (Ler alleles at the minor QTL and a Col allele at the major QTL) were compared to those in the LLL pool (Ler alleles at all QTL). The genes that were significantly differentially expressed between the two pools included several encoding transcription factors and signaling or transposon-related proteins.
