Abstract
D-factors are genetic elements that have the potential to exert a deleterious effect on the growth and reproductive fitness of Ophiostoma ulmi, the causative agent of Dutch elm disease [1,2]. They show cytoplasmic inheritance and are readily transmitted by hyphal anastomosis to other isolates in the same vegetative-compatibility (v-c) group; less efficient transmission is also possible between isolates in different v-c groups [3]. When a d-infected donor isolate and a “healthy” recipient isolate are paired on elm sapwood agar (ESA) medium, altered sectors of growth (d-reactions) are observed in the recipient isolate on either side of the area where the two colonies initially merged. In its most severe form a d-reaction can result in almost complete cessation of growth of the recipient culture.
