“…A ocorrência de polimorfi smos no íntron 1 e sua associação ao crescimento já foram relatadas em peixes como o linguado (Kang et al, 2002), o salmão-do-atlântico (Gross & Nilsson, 1999), a truta "Artic charr" (Salvelinus alpinus) (Tao & Boulding, 2003) e a dourada (Sánchez-Ramos et al, 2006). Também foram observados polimorfi smos no gene GH, em regiões não codifi cadoras, associados à produção, em bovinos, aves e suínos (Kuhnlein et al, 1997;Zhou et al, 2005;Faria et al, 2006).…”

Resumo -O objetivo deste trabalho foi determinar a associação de polimorfi smos no gene do hormônio de crescimento GH1 às características corporais, em linhagens de tilápia-do-nilo (Oreochromis niloticus). Foram coletados fragmentos da nadadeira caudal de exemplares das linhagens, aos cinco meses de idade, para as análises de "polymerase chain reaction-restriction fragment lenght polymorphism" (PCR-RFLP). Foram realizadas as seguintes mensurações: comprimento total, comprimento padrão, altura, largura e comprimento da cabeça. Realizou-se a amplifi cação de um fragmento com 652 pb do gene GH1, com subsequente restrição com a enzima PstI. Para a análise de associação do marcador molecular com as características quantitativas, utilizou-se o procedimento GLM do SAS. O polimorfi smo descrito para o íntron 1, do gene GH1 da tilápia-do-nilo, apresentou correlação signifi cativa com o comprimento total, comprimento padrão, altura e largura corporal. Foi verifi cado que o genótipo PstI +/-está associado ao melhor crescimento, independentemente da linhagem. A associação verifi cada pode ter ocorrido em razão do efeito direto da regulação do próprio gene GH.Termos para indexação: Oreochromis niloticus, enzima de restrição, hormônio do crescimento, PCR-RFLP. Polymorphism in the GH1-PstI gene associated to corporal characteristics in Nile tilapia strainsAbstract -The objective of this study was to determine the association of polymorphisms in the growth hormone gene GH1 with the corporal characteristics in Nile tilapia (Oreochromis niloticus) strains. Fragments of the caudal fi n were collected from 5-month old fi shes for analysis by polymerase chain reaction -restriction fragment length polymorphism (PCR-RFLP). The following measurements were accomplished: total length, standard length, height, width, and head length. A fragment with 652 bp of the GH1 gene was amplifi ed with subsequent restriction with the enzyme PstI. For the analysis of the association of the molecular marker with the quantitative traits the SAS GLM procedure was used. The polymorphism described for the intron 1 of the GH1 gene of Nile tilapia had signifi cant correlation with total length, standard length, and body height and width. It was found that the genotype PstI +/-is associated with better performance regardless of strain. Such association may be due to direct effect of the GH gene own regulation.

“…Molecular markers for association analysis of target traits in aquatic animals can be used with 2 methods, including isolating a population marked for association analysis (Gross and Nilsson, 1999;Kang et al, 2002) and random selection of a population marked for associated analysis (Cnaani et al, 2003). In this study, these 2 methods were used together.…”

ABSTRACT. Mandarin fish (Siniperca chuatsi) is a traditionally cultured freshwater fish with high commercial value in China. To facilitate marker-assisted selection for genetic improvement of this species, 100 microsatellite markers identified in previous studies were characterized in the 25 largest and 25 smallest individuals. Twenty polymorphic loci were used to genotype 200 individuals, and the associations between their genotypes and growth traits were examined. We found that 9 genotypes at 8 loci Sin 135, Sin 166, were positively correlated with growth traits (body weight, body length, body height) in the mandarin fish population. The average of observed and expected heterozygosities were 0.71 and 0.59, respectively, and the average 8927 Microsatellite markers associated with growth traits ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (3): 8926-8934 (2015) polymorphism information content value was 0.54, indicating that the population had high genetic diversity. The markers developed in this study are useful for selection of genetic breeding in this species and its related species.

“…Although the genes that affect a polygenic trait such as growth are unknown, a number of potential candidate genes have been recognized. Candidate genes have been selected based on a known relationship between physiological or biochemical processes and a trait, and then tested as putative quantitative trait loci (QTLs) (Kang et al, 2002). Growth hormone is the major regulator of postnatal growth and metabolism in mammals and thus affects growth rate, milk production, and aging by modulating the expression of many genes (Ho and Hoffman, 1993;Chung et al, 1998).…”

The growth hormone gene (GH) affects animal growth and is a potential target for genetic studies of variation related to growth traits. In this study, we analyzed single nucleotide polymorphisms (SNPs) in GH intron regions and their associations with growth traits in large yellow croaker, Larimichthys crocea, from Zhejiang and Fujian stocks. The results of PCR-single strand conformation polymorphism showed two haplotypes of intron 1, named AA and AB genotypes, in Zhejiang stock. AB exhibited an SNP at position 196 (G A) that was negatively correlated with body height and positively correlated with standard length/body height (P 0.05). Two different genotypes, CC and CD, were identified in intron 2 in Fujian stock, with CD showing an SNP at position 692 (T C). The CD genotype had a significantly positive correlation with both weight and total length (P 0.01). These basic data highlight the potential for using GH as a genetic marker of fish growth in marker assisted selection.
