The European S and F intersterility groups of <i>Heterobasidion annosum</i> may represent sympatric protospecies

Abstract: Abstract:In those regions of Europe where they coexist, the F and S intersterility groups (ISGs) of Heterobasidion annosum (Fr.) Bref. are primarily found on Abies spp. and Picea abies (L.) Karst., respectively. Eighty-three isolates of H. annosum were collected from Abies alba Mill. from 19 sites in Italy, including 10 Abies-Picea mixed conifer stands in the eastern Alps. The ISGs of a subsample of 34 isolates were determined by ISG-diagnostic arbitrary-primed (AP) PCR primers. For a subsample of 16 isolates,… Show more

“…In Italy H. annosum shows strong differences in terms of pathogenic activity between northern (Italian Alps) and southern (Apennine mountains) silver fir forests (Garbelotto et al, 1998). H. annosum populations of the Spanish Pyrenees could be closer to those of Italian Alps.…”

“…The presence of dsRNA in the recipient tip isolates was confirmed either by CF11 chromatography (isolates 99020 and 06111) or RT-PCR (isolate 93672). In order to confirm that the tip isolates were identical in genotype with the original recipient isolate, their genotypes were determined using both mitochondrial markers (primer pairs ML1 and ML2; White et al 1990, or Mito5, MLS, and MLF;Garbelotto et al 1998), and multilocus nuclear genotyping with the M13 primer . M13 fingerprinting was also used to control the quality of DNA samples used for the screening of viral genetic material potentially integrated in the host genome.…”
