Brycon is one of the main genera of Neotropical freshwater fish. In Brazil, Brycon species have been found in many hydrographic basins, such as the Amazon, Paraná, Paraguay, and Araguaia-Tocantins basins. We examined the phylogenetic relationships among the species Brycon orbignyanus, B. hilarii, B. cf. pesu, B. cephalus, B. falcatus, and B. gouldingi, using mitochondrial and nuclear molecular ...
Rye (Secale cereale L.) is important food crop in Russia. The study of the genetic diversity crops carried out using molecular markers. To identify effective primers, ISSR (Inter Simple Sequence Repeats), a method for determining DNA polymorphism, was used.The selection primers according to largest number polymorphic fragments, their clear amplification and reproducibility repeated PCR. Of 22 a...
Genetic analysis of 30 accessions of marvel grass (Dichanthium annulatum Forsk.), a tropical range grass collected from grasslands and open fields of drier regions, was carried out with the objectives of identifying unique materials that could be used in developing the core germplasm for such regions as well as to explore gene (s) for drought tolerance. Five inter-simple sequence repeat (ISSR) ...
Background: Arecanut (Areca catechu L.) is an important plantation crop of India belongs to the family Arecaceae. As it a highly cross-pollinated there significant difference among genotypes. Morphological traits used for determining diversity and relationships genotypes or variety are prone environmental influences. Thus, usefulness molecular markers has been investigated as means characterizi...
Catharanthus roseus or vinca produces over 130 TIAs with pharmaceutical value. Two of them, namely vinblastine (VB) and vincristine (VC), are species-specific and extensively used in anticancer chemotherapeutics. To detect C. roseus genotypes abundant in desired TIAs, contrasting genotypes should be analyzed via marker-assisted selection (MAS) to avoid analytical quantitation. A trustable morph...
There is scanty information on tamarind’s genetic diversity in Easter Kenya. The objective of this study was to determine the 64 tamarind accessions from Eastern Kenya using 12 Inter Simple Sequence Repeat (ISSR) markers. DNA extracted young apical leaves modified CTAB method and amplified standard PCR. data collected were scored as presence (1) or absence (0) bands then compared 100bp ladder a...
ISSR markers and morphometry determine genetic diversity and population structure in Hedera helix L.
ISSR markers and morphometry determine genetic diversity population structure in Hedera helix L. | Abdul Shakoor, Gul Zaib, Fang Zhao, Wuyang Li, Xincan Lan, Somayeh Esfandani-Bozchaloyi Agricultural Journals
در این تحقیق، تنوع ژنتیکی درون و بینجمعیتی 125 ژنوتیپ از نه جمعیت برودار (Quercus brantii) در جنگلهای زاگرس شمالی با استفاده از نشانگرهای ریختشناختی برگ، توالیهای تکراری سادة میانی (ISSR) و چندشکلی تکثیرشده بین رتروترانسپوزونها (IRAP) بررسی شده است. براساس تجزیة خوشهای مبتنی بر دادههای ریختاری، جمعیتهای مورد بررسی بهطور معنیداری از هم متمایز شدند و در شش خوشة اصلی قرار گرفتند...
—Sceptridium dissectum, the most variable North American grapefern species, demonstrates variation in degree of blade dissection, blade color, pinnule shape, and pinnule margins. Historically, various morphologies have been included within S. dissectum. For example, Clausen’s monograph recognized five infraspecific taxa in S. dissectum, of which only the morphologies of variety dissectum and ob...
خرما یکی از محصولات باغی مهم است. اهمیت خرما به دلیل صادراتی بودن آن و نیز ارزش غذایی بالا و محصولات متعدد و متنوعی دیگری است که از آن بدست می آیند. شناخت تنوع ژنتیکی و طبقه بندی ذخایر توارثی (ژرم پلاسم) از فعالیت های مهم و ضروری در به نژادی و مدیریت حفظ ذخایر ژنتیکی گیاهان می باشد. در این تحقیق 75 نمونه از 15 جمعیت درخت خرما به منظور ارزیابی تنوع ژنتیکی توسط نشانگرهای مولکولی issr و rapd مورد ...
