Abstract
In the present study, growth hormone (GH) gene and Cytochrome b gene in Salmo trutta caspius and Salmo trutta fario were discussed, the rate of relationships between salmonids were analyzed by GH and Cytochrome b gene. The GH gene is a genetics marker in nuclear DNA that expressed paternal traits in salmons, furthermore, Cytochrome b gene also is genetics marker that expressed maternal DNA in mitochondrial genomics. With two genes we documented that there were high homology between sequences of GH gene and Cytochrome b gene, hence the salmonids types, specially salmo trutta caspius, salmo salar and salmo trutta fario probably had similar ancient in bony fishes.
Highlights
The salmo types including, salmo trutta caspius (S. t. caspius), salmo salar
According to the annotation growth hormone (GH) genes, these are genes linked to economic traits and polymorphism genetics which are governed by many genes, Following to the sequences of the salmon GH gene and cytochrome b were published in the BLASTn on the National Centre for biotechnology information (NCBI) network service, was designed a fragment of almost 3kb. for S.t.caspius and S.t.fario (Figure 1)
Comparison of the GH gene and cytochrome b in the s. t. caspius and S. t. fario with other salmons: There are high homology between bony fishes, such as s. t. fario, s. salar, s. t. caspius and rainbow trout regarding marker genetics as mithocondrial genetics (Rezaei and Akhshabi, 2012), In related to, GH gene were compared between s. t. caspius was recorded in Genebank (JN241634.1) with s.salar was recorded in Genebank (AY614010), the result showed there were high homology between sequences, in figure 3, the number of exons of GH in s.salar more than s. t. caspius (6 exon in s. salar and 5 exons in s. t. caspius) but was similar almost the position of exons in s.salar and s. t. caspius
Summary
The salmo types including, salmo trutta caspius (S. t. caspius), salmo salar (S. Salar) and Salmo trutta fario (S. t. fario), is important for economic aquaculture industry. Fario), is important for economic aquaculture industry. They live in the part of rivers and exhibit homing behavior. The research on the marker of genetics most concentrated on the paternal and maternal traits in fishes. GH gene is an important trait in other animals, like cattle that regulate somatic growth in muscle and the skeletal body (Harvey et al.,1995; Rocha et al, 1991; Hoj et al, 1993; Pilla et al, 1994; Schlee et al, 1994a, b; Lagziel et al, 1996), and pigs (Casas-Carrillo et al.,1994; Nielsen et al, 1995)
