Evaluation of Pvpgip2 transgenic tobacco plants for resistance against P. parasitica var. nicotianae. Phenotype of transgenic tobacco lines Pvpgip2 2.1 (A), Pvpgip2 2005 (B), and wild type plants (C) on a highly infected soil at 10 days after planting. The development of stem lesions was evaluated using a linear scale of 1–10, where 1 was no disease and 10 was a dead plant according to Csinos (1999). Comparative evaluation of resistance in two transgenic homozygous lines expressing PvPGIP2 and reference genotypes of Nicotiana plants with different degree of resistance in greenhouse conditions (D). Bars represent mean values with standard error (N = 50). Columns designated with the same letter are not significantly different (P > 0.05). The photographs were obtained at 100 cm of distance and are representative of one typical event. Nicotiana rustica (PI 499174), Nicotiana alata (PI 42334), Nicotiana longiflora (PI 555533), Nicotiana benthamiana (PI 555478), Nicotiana debneyi (PI 503320), Nicotiana megalosiphon (PI 555536).
