The presence of DNA fragments in tissues from rabbits given genetically modified (GM) soya-bean meal (solvent extracted) was investigated by using the polymerase chain reaction (PCR) approach. Moreover, the possible effects on cell metabolism were evaluated by determination of several specific enzymes in serum, heart, skeletal muscle, liver and kidney. The chloroplast sequence for tRNA Leu by u...

Several cover crops with potential for use in tropical and subtropical regions were assessed for susceptibility to three common species of root-knot nematode, Meloidogyne arenaria, M. incognita, and M. javanica. Crops were selected based on potential use as organic amendments in anaerobic soil disinfestation (ASD) applications. Nematode juvenile (J2) numbers in soil and roots, egg production, a...

Winter oilseed rape (OSR) can be grown intercropped with frost-sensitive service plant mixtures. This practice may reduce weed pressure and contribute to providing N for OSR after freezing. However, there is little knowledge of how plants interact together the soil in diverse annual crop To assess these interactions, two contrasting legume were selected: faba bean grass pea, as well a non-legum...

Abstract Aim Intercropping often leads to improved productivity of individual species compared monocultures. We have practically little knowledge facilitation effects in different intercropping systems and their importance creating soil legacies that can indirectly affect the succeeding crop a rotation through plant-soil feedback (PSF) effects. Methods To test this, we used two-phased field exp...

Phaseolus vulgaris L. (Fabaceae) forms symbioses with arbuscular mycorrhizal fungi (AMF) and nitrogen-fixing rhizobia (NFB). The tripartite relationship uses molecular singals to establish intracellular in roots. goal of this study was determine if Rhizobium tropici CIAT 899 exogenous riboflavin (vitamin B2) have an effect on AMF species selection root colonization P. vulgaris. Using SSU rRNA f...

A new species, Caliothrips tongi, is described from eastern China, and an old record of the North American bean thrips, Caliothrips fasciatus (Pergande), from the same area is considered unreliable. Oneilliella pallidizonata Kudo is transferred to Caliothrips as a new combination.
