Transiently effective VIGS using TRV is a strong technique for functional genomics in plants.
Even pTRV1 and pTRV2 empty vector transiently expressed in planta, systemic leaves often show curling or rolling phenotypes like typical viral symptoms.
Generally, we can generate hairpin structured RNAi transgenic plants for plant gene silencing.
How about pTRV1 and pTRV2 co-expressing stable transgenic? Is it possible to render a much stronger silencing effect? As viral symptom, is impossible to generate stable transgenic?
