Paratylenchus shenzhenensis n. sp. was collected from the rhizosphere soil of Anthurium andraeanum in Shenzhen, Guangdong Province, China. The new species is characterized by having a female with a small body (249-302 μm), well developed stylet (17-21 μm), rounded head with four submedian lobes and lip-region with a slight depression at the oral area, small post-vulval uterine sac with a few ve...

attempts were made to present a practical key for identification of small strongyles, the identification ofwhich seems to be a difficult task to do. 4000 nematodes collected from the large intestine of horses anddonkeys were examined. 18 species of small strongyles of horse and 15 of donkey were found. from 6species of large strongyles found in both animals, we only dealt with 3 of triodontopho...

From November 1997 to June 1998, 3,118 specimens of Echinogammarus stammeri (Karaman, 1931) (Amphipoda) were collected from the River Brenta (Northern Italy) and examined for larval helminths. Larvae of Polymorphus minutus (Goeze, 1782) singly infected the hemocoel of 23 (0.74%) crustaceans; all these larvae were cystacanth stages. This is the first record of Polymorphus minutus in E. stammeri....

Carbohydrate-protein recognition is central to many biological processes. Enzymes that act on polysaccharide substrates frequently contain noncatalytic domains, "carbohydrate-binding modules" (CBMs), that target the enzyme to the appropriate substrate. CBMs that recognize specific plant structural polysaccharides are often able to accommodate both the variable backbone and the side-chain decora...

Seven new species of Aleurodamaeus (Oribatida: Aleurodamaeidae) from South Africa are described: A. salvadordalii sp. nov., A. vicinus sp. nov., A. angelae sp. nov., A. niedbalai sp. nov., A. minutus sp. nov., A. woasi sp. nov. and A. prominens sp. nov. Their distribution in South Africa is discussed. Aleurodamaeus deswardti (Hugo, 2010) comb. nov. is proposed. A key to all South African specie...

Cephalotes minutus (Fabricius, 1804) Myrmicinae Sebastiani et al. 433 (HARA) Containing approximately 75 genera and 1.300 species, Malpighiaceae is one of the most diverse families of tropical and subtropical lianas and shrubs worldwide, which is predominantly distributed within the neotropics (Anderson, 2013). In Brazil, Malpighiaceae is represented by 44 genera and approximately 561 species d...

BACKGROUND The yeast Saccharomyces cerevisiae, a promising host for lignocellulosic bioethanol production, is unable to metabolize xylose. In attempts to confer xylose utilization ability in S. cerevisiae, a number of xylose isomerase (XI) genes have been expressed heterologously in this yeast. Although several of these XI encoding genes were functionally expressed in S. cerevisiae, the need st...
