Resistance to Grapevine leafroll associated virus-2 is conferred by post-transcriptional gene silencing in transgenic Nicotiana benthamiana.

abstract：:Several reports of promoters from plants, viral and artificial origin that confer high constitutive expression are known. Among these the CaMV 35S promoter is used extensively for transgene expression in plants. We identified candidate promoters from Arabidopsis based on their transcript levels (meta-analysis of avail...
