ZIKV is a singlestranded positive-sense RNA virus encoding three structural proteins, including nucleocapsid protein C, prM/M,envelope glycoprotein E, and seven non-structural proteins.Since 2015.展开更多

These DNA viruses are characteristic for their ability in quickly multiplying viral genetic materials without integrating into the genome of plants, which makes them ideal for developing viral vectors for plants bioengineering. Geminivirus-derived vectors can be classified into expression vectors and virus-induced gene silencing（VIGS） vectors. Details of the design, construction, application and improvements of these geminivirus vectors are summarized and discussed.展开更多
