For detecting qtl in the whole swine genome,1068 pigs from three F2 populations con-structed by crossing European Wild boar and Pietrain (W譖),Meishan and Pietrain (M譖),and Wild Boar and Meishan (W譓) were genotyped for genetic markers evenly spaced at approximately 20 cM inter-vals. A qtl analysis was performed using a least-squares method. Here the results of the qtl analysis on the porcine chromosome 7 are presented. qtl for carcass composition (*** weight,carcass length,backfat depth,abdominal fat and bacon meat) were mapped in the chromosomal region CYPA/CYPD-TNFB-S0102 in M譖 and W譓,but not in W譖. The qtl was additive. Surprisingly, in contrast to the parental phenotype, the qtl alleles from fatty Meishan were associated with thinner backfat than Pietrain and Wild Boar alleles,suggesting that the genome of the fatty Meishan pig contains genes which can reduce fat content of carcass substantially.

Coincidence in map positions between pathogen-induced defense-responsive genes and quatitative resistance loci in rice

Quantitative disease resistance conferred by quantitative trait loci (qtls) is presumably of wider spectrum and durable. Forty-four cDNA clones, representing 44 defense-responsive genes, were fine mapped to 56 loci distributed on 9 of the 12 rice chromosomes. The locations of 32 loci detected by 27 cDNA clones were associated with previously identified resistance qtls for different rice diseases, including blast, bacterial blight, sheath blight and yellow mottle virus. The loci detected by the same multiple-copy cDNA clones were frequently located on similar locations of different chromosomes. Some of the multiple loci detected by the same clones were all associated with resistance qtls. These results suggest that some of the genes may be important components in regulation of defense responses against pathogen invasion and they may be the candidates for studying the mechanism of quantitative disease resistance in rice.
