Taxonomy of Fusarium oxysporum f.sp. albedinis
The authors of the work cited in Reporting Service 93/144 stress to the EPPO Secretariat that genetic homogeneity is found among Fusarium oxysporum isolates obtained from date palm leaves (presumably f.sp. albedinis; EPPO A2 quarantine pest), not among all isolates from different parts of date palm. Some isolates from roots (and also from lucerne or from soil) belong to the same RFLP group as the leaf isolates. Others belong to other groups.
