It is a new attempt by taking agricultural landscapes into the development system of scenic spot for their mutual support and promotion. With the detail plan of Yanmen Mountain Scenic Spot in Zhaixing Mountain Scenic Area as a study case, the authors studied how to take agricultural landscapes into the development system of scenic spot.展开更多

[ Method] Cloning and sequence analysis of 5' flanking region and exon of inihibinα (INHE) precursor gene in twenty ewes between non-seasonal estrous breed (Haimen goats) and seasonal estrous breed (Anhui white goats) was analyzed in this study. [ Result] Compared with Anhui white goats, INHα precursor gene in Haimen goats had three SNP but no amino acid change, while its nucleotide homology was 99.7% and amino acid homology was 100%. The nucleotide homology of INHα precursor gene in goat, cattle, pig, person, chicken, horse, rat and dog ranged from 12.7% to 96.5%. [ Conclusion] INHα precursor gene tends to be highly conserved in species, and any change of nucleotide and amino acid maybe directly influence the function of the whole gene coding and regulation.展开更多
