a polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) test was performed to investigate the allele frequencies of the insulin-like growth factor (igf1 and igf2 genes) in 90 broilerchickens. a 793 bp fragment of igf1 gene and 1146 bp fragment of igf2 gene were amplified and digested with hinfi and hsp92ii restriction enzymes,respectively. two types of alleles of a and b...

in this study we estimated the allele and genotype frequencies of scd1 and dgat1 gene polymorphism. the analysis was conducted on 408 holstein cows from five dairy herds in isfahan province. genotypes were identified using pcr-rflp technique. two genetic variants (a and v) of the scd1 gene were observed in this experiment. the frequency of a-allele ranged from 0.49 to 0.66, while frequency of v...

background: major histocompatibility complex (mhc) in chicken has profound influence on resistance/susceptibility to disease, and production and reproduction traits. microsatellite marker lei0258 is a genetic indicator for mhc haplotypes. recognizing diversity of mhc haplotypes in selectively bred populations will be helpful for selecting population resistant to disease and development of effec...

Host plant resistance provided by solid stems has been the most effective means for mitigating wheat stem sawfly (WSS) (Cephus cinctus Norton) damage in spring and winter (Triticum aestivum L.). The trait originates from cultivar “Rescue” is associated with a quantitative locus allele Qss.msub-3BL.b that explains majority of variation solidness. Recently, new Qss.msub-3BL allele, designated Qss...

12 representative  high  quality  xian/indica  rice varieties were selected as test materials. Seven grain length genes including  GS3 ,  LGY3 qGL3 GL7 SLG7 TGW6 and  GS9 , and three width GW8 GW5  and  GS5  were tested by molecular marker. The results showed that: All have the  gs3  long-grain allele, Ezhong 5, Yujing 91, Yuzhenxiang,...

background: cytokines are cell signaling molecules which upon release by cells facilitate the recruitment of immune-modulatory cells towards the sites of inflammation. genetic variations in cytokine genes are shown to regulate their production and affect the risk of infectious as well as autoimmune diseases. intron-3 of interleukin-4 gene (il-4) harbors 70-bp variable number of tandem repeats (...

Increased trait impulsivity is a core element in several mental disorders. Given the durable and consistent nature of impulsivity, studies have explored its relation to stable biological measures. Variation catecholaminergic neurotransmission by genetic variants could be one these substrates. Here, 905 participants European-ancestry completed Barratt Impulsiveness Scale–11 were genotyped three ...

Porcine Stress Syndrome (PSS) is a disorder codified by the ryanodine receptor 1 gene (RYR1) and affects both animal welfare quality of meat product. As consequence, individuals with this syndrome generate great worldwide economic losses in porcine industry. In Argentina, Buenos Aires Province most involved on activity, productions are to be open field higher frequency pigs diverse pathologies....
