title: Transgenic peas (Pisum sativum) expressing polygalacturonase inhibiting protein from raspberry (Rubus idaeus) and stilbene synthase from grape (Vitis vinifera).
abstract: The pea (Pisum sativum L.) varieties Baroness (United Kingdome) and Baccara (France) were transformed via Agrobacterium tumefaciens-mediated gene transfer with pGPTV binary vectors containing the bar gene in combination with two different antifungal genes coding for polygalacturonase-inhibiting protein (PGIP) from raspberry (Rubus idaeus L.) driven by a double 35S promoter, or the stilbene synthase (Vst1) from grape (Vitis vinifera L.) driven by its own elicitor-inducible promoter. Transgenic lines were established and transgenes combined via conventional crossing. Resveratrol, produced by Vst1 transgenic plants, was detected using HPLC and the PGIP expression was determined in functional inhibition assays against fungal polygalacturonases. Stable inheritance of the antifungal genes in the transgenic plants was demonstrated.
