BERBEE, M. L., AND TAYLOR, J. W. 1992. 18s ribosomal RNA gene sequence characters place the human pathogen Sporothrix schenckii in the genus Ophiostoma. Experimental Mycology 16, 87-91. Using the sequence of the gene for the 18s subunit of ribosomal RNA, we show that the asexual human pathogen Sporothrix schenckii lies phylogeneticaily within the sexual genus Ophiostoma. By distance or maximum ...

Eriophyoid mites from Qinghai Province, northwestern China were studied herein. Up to now, only six species have been reported from Qinghai Province. In field surveys, 17 eriophyoid mite species were collected, among which nine species were found new to science. The new species and their host plants are listed as follows: Acaphyllisa tuberculumaesp. n. on Populus sp. (Salicaceae); Proiectus xin...

In order to contribute to taxonomic information on Tetranychid mites (Acari: Tetranychidae) in South America, surveys were conducted in Brazil (15 States and the Federal District) and Uruguay (one Department); 550 samples of 120 plant species were collected. Tetranychid mite infestations were confirmed in 204 samples, and 22 species belonging to seven genera of the Bryobiinae and Tetranychinae ...

Dutch elm disease fungus Ophiostoma novo-ulmi contains a hydrolase activity which catalyses the resolution of racemic ethyl naproxen to the corresponding acid. The recombinant enzyme has been crystallized by the vapour-diffusion method in two crystal forms. The crystals of the first form belong to space group P2(1)2(1)2, with unit-cell parameters a = 115.9, b = 174.4, c = 62.1 A. The enzyme als...
