The number of alleles per SSR locus ranged from 4 (VVIn16) to 20 (VVIv67) and the mean allele number per locus was 10.09. Expected locus heterozygosity ranged from 0.586 (locus VVIb01) to 0.898 (locus (VVIv67)). The three cpSSR molecular markers presented variation in size both in cultivars and in wild Turkish accessions. Two size variants were detected for cpSSR3 (106 and 107 bp) for cpSSR5 (104 and 105 bp), and for cpSSR10 (115 and 116 bp). The six alleles in wild grapevines fell into three haplotypes B, C and D.

Here, we examined the correlation between egg-laying traits and <i>GH</i> gene polymorphisms and expression patterns in the muscovy duck (<i>Cairina moschata</i>). PCR single-strand conformation polymorphism was used to identify polymorphisms in intron 3 of <i>GH</i>. One single nucleotide polymorphism (g.3270 A &gt; G) was detected by sequencing, and the frequencies of the A and G alleles in the population were 0.65 and 0.35, respectively. A comparison test showed that the AA genotype group had more consecutive laying days and more eggs at 300 days than the GG genotype group (P &lt; 0.05); however, there was no significant difference for the age at first laying (P &gt; 0.05). Such a significant correlation between <i>GH</i> polymorphisms and egg-laying performance suggested that <i>GH</i> could be a candidate locus affecting the laying trait in muscovy duck. Furthermore, real-time fluorescent quantitative PCR demonstrated that <i>GH</i> is expressed in all selected tissues, but is highly expressed in the hypothalamic–pituitary–gonadal axis and heart. This unique expression pattern suggested that <i>GH</i> may exert its local physiological function through the autocrine or paracrine pathway during gonad development and growth in the muscovy duck. The data presented in this paper revealed <i>GH</i> polymorphisms and expression patterns in the muscovy duck and indicated a potential regulatory effect of GH on reproduction.</p>","PeriodicalId":55057,"journal":{"name":"Hereditas","volume":"151 1","pages":"14-19"},"PeriodicalIF":2.7,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1601-5223.2013.00016.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32174683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
