RNA-Seq of vitis viniferar: berry at veraison
The viral vector pIR was used to construct the VvVHP1;2 overexpressing vector. The spike-stalks of the grape clusters  were punctured with a hypodermic needle. A capillary tube was inserted into the resultant hole, and plasmid DNA was pipetted into the tube until fully soaked up by the grape clusters. The IL-60-BS vector was used as a helper plasmid.
