“…There are several different loci controlling plumage and the Extension (E) locus is one of the main loci affecting the relative distribution of black (eumelanin) and red (phaeomelanin) pigment (Kerje et al 2003). In particular, a gene called the MC1R has an important role in the regulation of eumelanin (black/brown) and pheomelanin (red/yellow) feather pigmentation of chickens (Hoque et al 2013;Kerje et al 2003). A number of E locus alleles in chickens have been identified and described such as E R , e + , e b , and e wh (Ellet 2000).…”

Asmara IY, Garnida D, Tanwiriah W, Partasasmita R. 2019. Qualitative morphological diversity of female Pelung Chickens in West Java, Indonesia. Biodiversitas 20: 126-133. Pelung chickens are indigenous chickens in Indonesia derived from Cianjur District, West Java Province. The chickens which are raised as singing chickens have a distinctive body shape compared to other local chickens. Regular contests are conducted as a media to show singing ability and performance including morphological characteristics of Pelung chickens. Pelung keepers believe that the chickens inherited their singing capability from their parents. Pelung keepers perceived qualitative traits for example plumage color as an indicator of a good female breed. The objective of this study was to determine the qualitative traits of female Pelung Chickens in West Java. This study recorded comb type, color of eye, beak, skin, plumage and shank including traditional name related to the morphological traits. A survey was conducted to gather data involving 160 chickens in four districts in West Java Province, including Cianjur, Sukabumi, Bandung, and Garut Districts. The results showed that adult female Pelung chickens have similar qualitative characteristics except for plumage color. The majority of pelung chickens in Bandung, Garut, and Sukabumi have black plumage, while in Cianjur District have yellow-brown color. The chicken contest seems to be the main factor dictating keepers’ preferences in terms of plumage color in Bandung, Garut and Sukabumi Districts. This study indicates a decreasing variation in plumage color of female Pelung chickens. These findings are important in terms of breeding strategy of Pelung chickens.

“…Different authors have carried out studies in poultry utilizing molecular markers (including SNPs) ( Sheng et al, 2013; Hoque et al, 2013 ). Currently, the search for SNP markers represents one of the favourite genotyping approaches because they are very abundant in the genome and amenable to high-throughput analysis ( Yang et al, 2013 ).…”

Expression profile of six stress-related genes and productive performances of fast and slow growing broiler strains reared under heat stress conditions

et al. 2015

High temperature is one of the prominent environmental factors causing economic losses to the poultry industry as it negatively affects growth and production performance in broiler chickens. We used One Step TaqMan real time RT-PCR (reverse transcription polymerase chain reaction) technology to study the effects of chronic heat stress on the expression of genes codifying for the antioxidative enzymes superoxide dismutase (SOD), and catalase (CAT), as well as for heat shock protein (HSP) 70, HSP90, glucocorticoid receptor (NR3C1), and caspase 6 (CASP6) in the liver of two different broiler genetic strains: Red JA Cou Nu Hubbard (CN) and Ross 508 Aviagen (RO). CN is a naked neck slow growing broiler intended for the free range and/or organic markets, whereas RO is selected for fast growing. We also analysed the effect of chronic heat stress on productive performances, and plasma corticosterone levels as well as the association between transcriptomic response and specific SNPs (single nucleotide polymorphisms) in each genetic strain of broiler chickens. RO and CN broilers, 4 weeks of age, were maintained for 4 weeks at either 34 °C or 22 °C. The results demonstrated that there was a genotype and a temperature main effect on the broilers' growth from the 4th to the 8th week of age, but the interaction effect between genotype and temperature resulted not statistically significant. By considering the genotype effect, fast growing broilers (RO) grew more than the slow growing ones (CN), whereas by considering the temperature effect, broilers in unheated conditions grew more than the heat stressed ones. Corticosterone levels increased significantly in the blood of heat stressed broilers, due to the activation of the HPA (hypothalamic–pituitary–adrenocortical axis). Carcass yield at slaughter was of similar values in the 4 cohorts (genotype/temperature combinations or treatment groups), ranging from 86.5 to 88.6%, whereas carcass weight was negatively influenced by heat stress in both broiler strains. Heat stress affected gene expression by downregulating CASP6 and upregulating CAT transcript levels. HSPs, SOD and NR3C1 mRNA levels remained unaffected by heat stress. The differences found in the mRNA copies of CASP6 gene could be partly explained by SNPs.

“…white Herri with black nose and mouth. It has been reported that single mutations in MC1R gene can lead to either entirely or partially black animals [27–29]. For example, Kijas et al [27] identified a single nonsynonymous mutation at position 121 (Asp121Asn) of MC1R gene in pigs associated with both generally black colored and white or red pigs with black spots.…”

ObjectiveThis study was designed to characterize the DNA polymorphisms of the melanocortin-1 receptor (MC1R) gene in indigenous Saudi Arabian sheep breeds exhibiting different color coats, along with individuals of the Sawaknee breed, an exotic sheep imported from Sudan.MethodsThe complete coding region of MC1R gene including parts of 3′ and 5′ untranslated regions was amplified and sequenced from three the indigenous Saudi sheep; Najdi (generally black, n = 41), Naeimi (generally white with brown faces, n = 36) and Herri (generally white, n = 18), in addition to 13 Sawaknee sheep.ResultsFive single nucleotide polymorphisms (SNPs) were detected in the MC1R gene: two led to nonsynonymous mutations (c.218 T>A, p.73 Met>Lys and c.361 G>A, p.121 Asp>Asn) and three led to synonymous mutations (c.429 C>T, p.143 Tyr>Tyr; c.600 T>G, p.200 Leu>Leu, and c.735 C>T, p.245 Ile>Ile). Based on these five SNPs, eight haplotypes representing MC1R Ed and E+ alleles were identified among the studied sheep breeds. The most common haplotype (H3) of the dominant Ed allele was associated with either black or brown coat color in Najdi and Sawaknee sheep, respectively. Two other haplotypes (H6 and H7) of Ed allele, with only the nonsynonymous mutation A218T, were detected for the first time in Saudi indigenous sheep.ConclusionIn addition to investigating the MC1R allelic variation in Saudi indigenous sheep populations, the present study supports the assumption that the two independent nonsynonymous Met73Lys and Asp121Asn mutations in MC1R gene are associated with black or red coat colors in sheep breeds.
