Saprolegnia bulbosa sp. nov. isolated from an Argentine stream: taxonomy and comparison with related species
2007
Saprolegnia bulbosa sp. nov. was isolated from floating and decaying twigs and leaves in El Gato stream, Partido de La Plata, Buenos Aires Province, Argentina. The distinctive characteristics of S. bulbosa are the product of smooth oogonia and predominantly contorted monoclinous, androgynous and diclinous antheridia. The oogonial stalks are usually bent, curved or once coiled; oospores are subcentric, (1) 2–15 (45) per oogonium and are variable in size. Taxonomical description of this new species, its comparison with related oomycetes of the genus and the nucleotide sequences of the internal transcribed region (spacers ITS1, ITS2 and the gene 5.8S) of its rRNA gene are given here.
Indagini EPR su legni moderni e antichi
