Effects of temperature on the in vitro reproduction of Aphelenchoides rutgersi

L'influence de la température sur la reproduction d'#Aphelenchoides rutgersi en culture axénique a été étudiée. La température optimale de reproduction d'#A. rutgersi est de 28°C. A cette température, une femelle d'#A. rutgersi$pond en moyenne 60 oeufs pendant les 11 jours qui suivent sa maturation; les juvéniles commencent à éclore dès le deuxième jour; 80$ n'augmentent plus. A des températures inférieures à 28°C, les oeufs pondus sont moins nombreux, les éclosions plus tardives, et les durées minimale et moyenne de développement demandent au moins 2 jours de plus.

Detection of genetically modified plant products by protein strip testing: an evaluation of real-life samples

The determination of the presence of genetically modified plant material by the detection of expressed genetically engineered proteins using lateral flow protein strip tests has been evaluated in different matrices. The presence of five major genetically engineered proteins (CP4-EPSPS, CryIAb, Cry9C, PAT/pat and PAT/bar protein) was detected at low levels in seeds, seed/leaf powder and leaf tissue from genetically modified soy, maize or oilseed rape. A comparison between &quot;protein strip test&quot; (PST) and &quot;polymerase chain reaction&quot; (PCR) analysis of genetically modified food/feed samples demonstrates complementarities of both techniques. -® Springer-Verlag 2007</p

Guidelines for morpholino use in zebrafish

The zebrafish (Danio rerio) has emerged as a powerful model to study vertebrate development and disease. Its short generation time makes it amenable to genetic manipulation and analysis, and its small size and high fecundity make it especially well suited for large-scale forward genetic and chemical screens. Fast-developing zebrafish embryos are transparent, facilitating live imaging of a variety of developmental processes in wild-type and mutant animals. ... This brief document provides an updated set of guidelines regarding morpholino use in zebrafish that we anticipate will be of value for experimentalists as well as journal and grant reviewers, and decision makers
