Resistance levels to two strains of Potato virus Y (PVY) in transgenic potatoes cv. Achat
Horticultura Brasileira 19 (3), 348-350
Abstract: Two transgenic potato clones of cv. Achat, denominated 1P and 63P were challenged with two Potato virus Y strains (PVY^O and PVY^N), under greenhouse conditions, to be evaluated for resistance to these strains. Optical density values of the Elisa readings of samples from the transgenic plants were compared to readings from samples of the inoculated non-transformed plants. Clone 1P was extremely resistant to both PVY strains, reflected by not being systemically infected. Clone 63P, however, presented partial resistance to both PVY strains as local or systemic infection was delayed in some days. These results confirm the previously reported extreme resistance to PVY of clone 1P.
