The C-terminal domain of the 2b protein of Cucumber mosaic virus is stabilized by divalent metal ion coordination.

The main function of the 2b protein of Cucumber mosaic virus (CMV) is binding permanently the double stranded siRNA molecules in the suppression process of post-transcriptional gene silencing (PTGS). The crystal structure of the homologue Tomato aspermy virus (TAV) 2b protein is known, but without the C-terminal domain. The biologically active form is a tetramer: four 2b protein molecules and t...

A cucumber mosaic virus mutant lacking the 2b counter-defence protein gene provides protection against wild-type strains.

Several plant virus mutants, in which genes encoding silencing suppressor proteins have been deleted, are known to induce systemic or localized RNA silencing against themselves and other RNA molecules containing homologous sequences. Thus, it is thought that many cases of cross-protection, in which infection with a mild or asymptomatic virus mutant protects plants against challenge infection wi...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
