ABSTRACT
Abbas
MT, Hatif SA., Melatonin receptor A1 gene
polymorphism and breeding season in gazelle subgutturosa
marica, 22 (4):281-287, 2018. We describe a melatonin receptor A1
gene (MTNR1A)
polymorphism associated with breeding season in Gazelle subgutturosa marica in Iraq. Melatonin and genomic DNA were determined
March to November in blood taken from 11 female gazelle aged 2-4 years. We
found polymorphism among (MTNR1A) gene
sequences in 95% and 96% compared with MTNR1A gene of Cervus Nippon (Sika Deer): In 4 to 6 gazelles we found nucleotide transversion at 96% and
in 6-8 were 95% compatible with GenBank. While transition of
nucleotide between (11-13) and (12-14) to 96% and 95% respectively.
Amino acid (AA) expression was different between gazelles with non-sense 96%
and miss-sense 96% compatible with GenBank.
Melatonin peaked significantly (P < 0.01) during October and November and declined during
March, April and May. Six gazelles cycled in October and 5 in November. Our
results suggest that gazelle
(Gazella subgutturosa)
in Iraq are seasonal with most breeding occurring in October and November.
Results suggest that polymorphism in MTNR1A
gene sequence may be affected by season.
