it has been more than half a century that plant geneticists and breeders have been trying to assemble a combinationof genes in crop plants, in order to make them as suitable and productive as possible. plant transformation technology incrop plants was first undertakenin the 1980s based on the ability of foreign gene integration into host plant genome andregeneration of transformed plant cells i...

در جنگاکاری با گونه های بومی می بایست حفاظت از گوناگونی زمانی و ساختار جغرافیایی تنوع ژنتیکی گونه های جنگلی در نظر گرفته شود. برای تهیه اطلاعات کاربردی در مورد کارآمدی روشهای جمع آوری نمونه، ترکیب ژنتیکی ده جمعیت راش (حداقل 40 درخت در هر جمعیت) و نتاج آنها (بذور 10 درخت مادری در هر جمعیت، به میزان 7 بذر از هر درخت) توسط چهار لوکوس میکروساتلایتی پلی مورف بررسی شد. تکثّر آللی در نمونه های بذر بیش ...

'Gene flow' means the movement of genes. In some cases, small fragments of DNA may pass from one individual directly into the germline of another, perhaps transduced by a pathogenic virus or other vector, or deliberately via a human transgenic manipulation. However, this kind of gene flow, known as horizontal gene transfer, is rare. Most of the time, gene flow is caused by the movement or dispe...
