Elm breeding programs worldwide have relied heavily on Asian elm germplasm, particularly
Ulmus pumila, for the breeding of Dutch elm disease tolerant cultivars. However, the extent …

During the last decades, the development of ever more powerful genetic, molecular and
omic approaches has provided plant pathologists with a wide array of experimental tools for …

Interspecific hybridisation and gene flow from cultivated plants may have profound effects on
