Hemp (Cannabis sativa) is an important fiber crop, and native cultivars exist widely throughout China. In the present study, we analyzed the genetic diversity of 27 important Chinese native hemp cultivars, by using inter-simple sequence repeats (ISSR) and chromosome markers. We determined the following chromosome formulas: 2n = 20 = 14m + 6sm; 2n = 20 = 20m; 2n = 20 = 18m + 2sm; 2n = 20 = 16m +...

سابقه و هدف: میزان مرگ ناشی از سرطان معده در جهان رو به افزایش است. امروزه در بسیاری از سرطان ها ارتباط بسیار دقیقی بین ایجاد سرطان و تغییر میزان بیان رسپتور egf وجود دارد. شاید شناخته شده ترین این تغییرات بیان بالای گیرنده های her2 و her1 در سرطان معده باشد. هدف این مطالعه بررسی میزان بیان این دو گیرنده در آدنوکارسینوم های پیشرفته موضعی معده و ارتباط آن با بقاء بیماران می باشد. مواد و روش ها: ...

با توجه به تنوع بالای مورفولوژیکی در ارقام انار ایران، تنوع ژنتیکی 24 رقم انار با استفاده از نشانگرهای RAPD و ISSR مورد بررسی قرار گرفت. آغازگرهای RAPD در مجموع 131 قطعه DNA تکثیر نمودند که 29 قطعه آنها (14/22 درصد) چندشکل بودند. آغازگرهای ISSR نیز از مجموع 173 قطعه تکثیر شده، 29 (37 درصد) چند‌شکلی حاصل نمودند. میانگین محتوای اطلاعات چندشکل (PIC) برای آغازگرهای RAPD و ISSR به ترتیب 128/0 و 163/...

Interspecific hybrids between cultivars of eggplant (Solanum melongena L.) and its wild relative S. torvum, which has disease resistance and desirable traits for crop improvement, were obtained by cross-hybridization and embryo rescue. Twenty-one hybrid progenies were obtained and examined based on morphological traits, RAPD and ISSR markers. Five of them were confirmed to be true interspecific...

Molecular genetic fingerprints of eleven Hedychium species from Northeast India were developed using PCR based markers. Fifteen inter-simple sequence repeats (ISSRs) and five amplified fragment length polymorphism (AFLP) primers produced 547 polymorphic fragments. Positive correlation (r = 0.46) was observed between the mean genetic similarity and genetic diversity parameters at the inter-speci...

Genetic diversity was investigated in 60 individuals of Primula obconica from four natural populations (from Hubei, central China, and Sichuan, south-west China) and from cultivated material. Inter-simple sequence repeat (ISSR) techniques produced 249 polymorphic bands and identified 60 ISSR genotypes. Based on Shannon's index and Nei's genetic diversity, the genetic diversity detected in all n...

The genetic diversity and structure of the ant Atta robusta were assessed by ISSR (inter-simple sequence repeats) in 72 colonies collected from 10 localities in the Brazilian states of Espírito Santo (48 colonies) and Rio de Janeiro (24 colonies). The ISSR pattern included 67 bands, 51 of them (76.1%) polymorphic. Analysis of molecular variance (AMOVA) revealed a high level (57.4%) of inter-pop...

To address the “grand challenge” of biosphere sustainability, it is imperative that we examine the assumptions and philosophies underlying Information Systems sustainability research and expand research approaches. Despite calls for transdisciplinary research and recognition that addressing sustainability will require multiple perspectives, a review of the IS sustainability literature finds tha...

Genetic relationships of 16 cultivars of pigeonpea (Cajanus cajan (L) Millsp.) and its two wild relatives (C. albicans and C. lineatus) from different parts of the India were analysed using 22 random amplified polymorphic DNAs (RAPDs) primers and 10 inter simple sequence repeats (ISSRs) primers. Twenty two RAPD primers yielded 151 polymorphic markers (71.2%) with an average of 6.8 polymorphic b...

Inter-simple sequence repeat (ISSR) markers were used to evaluate the genetic stability of the micropropagated plants of Cannabis sativa over 30 passages in culture and hardening in soil for 8 months. A total of 15 ISSR primers resulted in 115 distinct and reproducible bands. All the ISSR profiles from micropropagated plants were monomorphic and comparable to mother plants, confirming the genet...
