BACKGROUND This paper describes the isolation and characterization of pregnancy-associated glycoproteins (PAG) from fetal cotyledonary tissue (FCT) and maternal caruncular tissue (MCT) collected from fallow deer (Dama dama) pregnant females. Proteins issued from FCT and MCT were submitted to affinity chromatographies by using Vicia villosa agarose (VVA) or anti-bovine PAG-2 (R#438) coupled to S...

Viral insect-borne plant pathogens have devastating impacts in agroecosystems. Vector-borne are often transmitted by generalist insects that move between non-crop and crop hosts. Insect vectors can wide diet breadths, but it is unknown which hosts serve as pathogen reservoirs host harbours the highest density of vectors. In Pacific Northwest USA, pea aphid (Acyrthosiphon pisum) a key virus vect...

The structure of the tetrameric Vicia villosa isolectin B4 (VVLB4) in complex with a cancer antigen, the Tn glycopeptide (GalNAc-O-Ser), was determined at 2.7 A resolution. The N-acetylgalactoside moiety of the ligand binds to the primary combining site of VVLB4 in a similar way as observed for other Gal/GalNAc-specific plant lectins. The amino acid moiety of the Tn antigen is largely exposed t...

In a natural ecosystem, endophytic fungi in the internal tissues of plants help to improve growth host and decrease negative effects biotic abiotic stresses without having adverse effects. Japan, Vicia villosa (hairy vetch), legume plant with high capacity fix nitrogen, is usually used as cover crop before soybeans enhance fertility structure soil. This study aimed isolate associated different ...

This study investigated the effects of crop rotations and different ratios dairy manure fertilizer on nitrogen loss rice yield in Erhai Lake basin. Two kinds herbages were set rotation: Ryegrass (Lolium multiflorum cv.‘Tetragold’) (R) Villose Vetch (Vicia villosa var. Glabresens) (V). The experiment involved two-year field tests with nine management treatments. results showed that rice-Vicia ro...
