ISSR molecular markers have been used to investigate genetic diversity of oca (Oxalis tuberosa Mol.), an Andean neglected tuber crop species. Sampling procedure allowed a preliminary study of the genetic diversity at the intraand intervarietal levels. Twenty tuber lots conserved in situ in the microcentre of Candelaria and ex situ in the Toralapa Centre (Bolivia) were identified. Four ISSR prim...
Morpho-agronomic and molecular (RAPD and ISSR markers) data were used to evaluate genetic distances between papaya backcross progenies in order to help identify agronomically superior genotypes. Thirty-two papaya progenies were evaluated based on 15 morpho-agronomic characteristics, 20 ISSR and 19 RAPD primers. Manhattan, Jaccard and Gower distances were used to estimate differences based ...
Twenty-seven accessions of Lippia alba Mill. collected in Rio Grande do Sul state, Brazil, were analysed by ISSR and RAPD markers to evaluate their genetic variability and relationships. Six ISSR primers and four RAPD primers generated 120 amplified fragments, most of which were polymorphics. The overall genetic variability among accessions was very high when compared with other plant species. ...
بیماری پوسیدگی ریشه و طوقه چغندرقند ناشی از قارچ pythium aphanidermatum، یکی از مهمترین بیماری های چغندرقند می باشد. به منظور بررسی تنوع ژنتیکی عامل این بیماری، از مزارع چغندرکاری استان های آذربایجان غربی، خراسان، فارس، تهران، کرمانشاه، لرستان، مرکزی و همدان نمونه برداری شد. جدایه های بدست آمده از نمونه های خاک و ریشه های چغندرقند دارای علائم پوسیدگی، پس از خالص سازی بر اساس خصوصیات ریخت شناسی ...
ریزازدیادی تجاری انگور ممکن است بواسطه بروز تغییرات فنوتیپی و ژنوتیپی در گیاهان حاصل از کشت بافت دچار محدودیت شود. در این تحقیق، هدف بررسی یکنواختی ژنتیکی در ژنوم هسته-ای، بین گیاه مادری و گیاهچه های حاصل از چند واکشت در طی پروسه ی باززایی در in vitro می باشد. پنج رقم مختلف انگور به نام های، ترکمن 6، ترکمن 8، کشمشی قرمز، صاحبی نیشابور و سیاه سعدی درگز برای آنالیز (rapd) و (issr) و ارزیابی ثبات ...
The DNA polymorphism among 92 selected tef genotypes belonging to eight origin groups was assessed using eight inter simple sequence repeat (ISSR) primers. The objectives were to examine the possibility of using ISSR markers for unravelling genetic diversity in tef, and to assess the extent and pattern of genetic diversity in the test germplasm with respect to origin groups. The eight primers w...
A large number of micropropagated plantlets of banana, Musa acuminata var. Nanjanagudu Rasabale (NR), that were developed from axillary shoot bud explants over 10 years ago were screened for genetic variation, if any, using RAPD (Random Amplified Polymorphic DNA) and ISSR (Inter-Simple Sequence Repeats) markers. Of the 4000 in vitro plantlets, 11 were used for screening that involved shoot cult...
Molecular characterization of 19 Jatropha accessions that included 15 accessions of J.curcas and 4 different species was carried out using 3 different markers systems. Highest polymorphism (96.67%) was recorded by RAPD followed by DAMD (91.02%) and ISSR (90%). Polymorphism Information Content (PIC) was higher for DAMD (0.873) and almost equal for RAPD (0.863) and ISSR (0.862) markers, whereas R...
Successful conservation of fish such as Plectropomus species depend on analysis of genetic signature and relations among fish species and subspecies. Knowledge about the genetic signature and structure of Plectropomus species needs to increase several times to enable us for conserve these economic fish in the future. The current study aims to develop and analysis of genetic signature for three ...
