چکیده مقاله :
Camels have been regarded as the desert ship and they play multi-utility role in the world. Estimation of genetic parameters is foremost step towards managing the genetic resources for their conservation and sustainable utilization. Microsatellite markers have been extensively used in cattle, sheep, goat and camels. However, genetic characterization studies on camels has been poorly recorded. There has been a rapid increase in amount of molecular data produced from indigenous camel populations, which clearly shows awareness among the scientific community. Based on the studies carried out in Australia, Kenya, Saudi Arabia, Canary Islands, India, Egypt and Tunisia the camels have shown very wide genetic diversity via the predefined microsatellite markers. It is highly recommended that to use following microsatellite markers to find the highly informative heterozygosity data: YWLL08, YWLL09, YWLL38, YWLL44, YWLL59, VOLP03, VOLP08, VOLP10, VOLP32, VOLP67, LCA66, CVRL01, CVRL05, CVRL06, CVRL07 and CMS50. These markers have shown a high level of allelic richness and polymorphic information content. Therefore, future genetic diversity analysis on camel can be based on these highly useful markers.
شترها به عنوان کشتیهای صحرا شناخته شده و کاربردهای مختلفی در جهان دارند. برآورد پارامترهای ژنتیکی نخستین گام در مدیریت منابع ژنتیکی برای حفاظت و استفاده مناسب از آنها است. نشانگرهای ریزماهواره به طور وسیعی در گاو، گوسفند، بُز و شتر به کار گرفته شدهاند. ولی مطالعات صورت گرفته در زمینه تعیین خصوصیات ژنتیکی بر روی شترها اندک است. افزایش سریعی در حجم دادههای مولکولی حاصل از جمعیتهای شتر بومی مشاهده میشود. این موضوع حاکی از آن است که سطح آگاهی از این موضوع در جوامع علمی مناسب است. بر مبنای مطالعات صورت گرفته در استرالیا، کنیا، عربستان سعودی، جزایر قناری، هندوستان، مصر و تونس، تنوع ژنتیکی نشانگرهای ریزماهواره در شترها از سطح بالایی برخوردار است. برای یافتن دادههای هتروزیگوسیتی مفید توصیه میشود که نشانگرهای ریزماهواره YWLL08، YWLL09، YWLL38، YWLL44، YWLL59، VOLP30، VOLP08، VOLP10، VOLP32، VOLP67، LCA66، CVRL01، CVRL05، CVRL06، CVRL07 و CMS50 استفاده گردد. این نشانگرها سطح بالایی از غنای آللی و محتوای اطلاعات چند‌شکلی را نشان میدهند. بنابراین آنالیزهای تنوع ژنتیکی بر روی شترها در آینده میتواند بر مبنای این نشانگرهای بسیار مفید صورت گیرد.
