Genetic variation in homothallic and hyphal swelling isolates of Pythium ultimum var. ultimum and P. utlimum var. sporangiferum.

Molecular plant-microbe interactions : MPMI - 1 Jan 2000

Francis D M, Gehlen M F, St Clair D A

Abstract excerpt

Genetic variation in a collection of 22 Pythium ultimum isolates was analyzed using restriction fragment length polymorphisms (RFLPs), random amplified polymorphic DNA (RAPD), and sequence characterized amplified regions (SCARs) as genetic markers. Qualitative evidence for the occurrence of sexual outcrossing in the field, asexual mechanisms affecting variation, and differences in aggressiveness between isolates...
