RAPD profiling in detecting genetic variation in Stellaria L. (Caryophyllaceae)

Genetic Variability Evaluation Among Iraqi Rice (Oryza sativa L) Varieties using RAPD Markers and Protein Profiling

Genetic variability and relationships among ten rice varieties were studied by using 20 decamer random primers and SDSPAGE methods. Out of 22, 20 Random Amplified Polymorphic DNA (RAPD) primers revealed polymorphism, while the remaining 2 primers showed no reaction. The primers produced a total of 109 bands, of which 62 (56.88%) were polymorphic. The number of polymorphic fragments for each pri...

شمارش کروموزومی برخی گونه های (Stellaria L. (Caryophyllaceae و بعضی تاکسونهای مرتبط در ایران

شمارش کروموزومی 23 جمعیت متعلق به 3 جنس و 8 آرایه از تیره میخک ( زیر تیره Alsinoideae) از ایران گزارش می شود. اولین گزارش کروموزومی برای گونه های S. persica (2n=28)، S. alsinoides (2n=2x=30) و Mesostemma kotschyanum subsp. kotschyanum ( 2n=32) ارائه می شود. گونه های جنس Stellaria به دو گروه تتراپلوئید و دیپلوئید تقسیم بندی می شوند. شمارش کروموزومی برای شش تاکسون از Stellaria (Caryophyllaceae) و...

Genetic polymorphism in rice (Oryza sativa L.) through RAPD analysis

Random Amplified Polymorphic DNA (RAPD) assay was performed to estimate genetic polymorphism in six different rice (Oryza sativa L.) cultivars viz. Basmati 370, DM 25, IRATOM 24, Binadhan 6, TNDB 100 and Y 1281. Three out of the 15 decamer random primers showed amplification of genomic DNA in 24 individuals. The primers produced a total of 26 bands of which 14 were polymorphic. Proportion of po...

Assessment of genetic variation within Indian mustard (Brassica juncea L.) germplasm using RAPD markers

Molecular cloning of a cDNA encoding cytochrome c of Stellaria longipes (Caryophyllaceae)--and the evolutionary implications.

A cDNA clone encoding cytochrome c of Stellaria longipes was isolated and characterized. The nucleotide and predicted amino acid sequences were highly similar to those from other plant, fungal, and animal species. No significant polymorphism was observed among different genotypes (ecotypes). The S. longipes genome contained a low copy number of nucleotide sequences of cytochrome c. The gene exp...
