Transgenic plants, plant tissue, and propagation materials are disclosed that exhibit or convey increased resistance to pathogens of multiple higher-order phylogenetic lineages. The disclosed transgenic plants and plant tissues include plant cells containing a DNA construct encoding Gastrodia Anti-Fungal Protein (GAFP), also known as gastrodianin, an anti-fungal gene naturally occurring in a Chinese orchid, Gastrodia elata. Transgenic plants disclosed include herbaceous plants as well as woody plants, including fruit trees. Disclosed transgenic plants can also be beneficially utilized as rootstock, for instance rootstock for stone fruit crops such as peach, thereby conferring enhanced disease resistance to the rootstock without genetically altering the scion
