Genetic variation of Phoma sorghina isolates from southern Africa and Texas
Original language description
Genetic variation of Phoma sorghina, an ubiquitous facultative phytopathogen was studied on 41 isolates cultivated from surface-sterilized sorghum grains and originating from South Africa and Texas. Pearl millet isolates from Namibia were also included.Most of the isolates from Texas produced intensive red pigments, especially on Czapek-Dox agar plates. Many African isolates formed conspicuous dark radial substrate hyphae with intercalated chlamydospores on oatmeal plates. Conidial dimensions and shapewere very variable (mean lengths 4.5-5.7 ium). Haplotypes were defined based on 53 markers from banding patterns obtained with rep-PCR (primers: M13core, ERIC 1R). The shared geographic origin was partially reflected in the clades of the haplotype phylogram. The values of GST were intermediate; 16 ? 37 percent of the variation was found between the populations. Nm values of gene flow were 0.84 - 1.15
