Genetic variation of Phoma sorghina isolates from southern Africa and Texas

Popis výsledku v původním jazyce

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
