“…Combination of several pvr genes can, however, be very difficult or impossible using phenotypic screening because of the masking effect of genes and (or) the close interaction between distinct potyviruses inoculated to the same plant (Marchoux et al 1993). When a breeding line already has a gene, for example Pvr4, which controls resistance to all PVY pathotypes, it cannot be distinguished from other lines with Pvr4 plus other genes involved in PVY resistance except if DNA markers are available for each resistance gene.…”

The Pvr4 resistance gene in pepper confers a complete resistance to the three pathotypes of potato virus Y (PVY) and to pepper mottle virus (PepMoV). In order to use this gene in a marker-assisted selection (MAS) program and to permit the pyramiding of several potyvirus resistance genes in the same cultivar, tightly linked amplified fragment length polymorphism (AFLP) markers were obtained by the bulked segregant analysis method. Eight linked AFLP markers were mapped in an interval from 2.1 +/- 0.8 to 13.8 +/- 2.9 cM around this locus. The closest codominant AFLP marker was converted into a codominant CAPS (cleaved amplified polymorphic sequence) marker using data from the alignment of the two allele sequences. We have further characterized the relevance of the CAPS marker for MAS programs in different pepper breeding lines.

“…Disease development resulting from new systemic spread within transgenic plants. The movement of a virus from the initial site of infection throughout a plant, called systemic infection, requires expression of one or more viral genes (a dedicated movement protein, coat protein, and/or viral proteins) and a permissible host plant (Hull, 1989;Maule, 1991;Dawson et al, 1988;Marchoux et al, 1993;Dolja et al, 1995;Cronin et al, 1995;Valkonen and Somersalo, 1995). If a virus is unable to move from the initial site of infection, these infections are called subliminal.…”

The OECD is a unique forum where the governments of 30 democracies work together to address the economic, social and environmental challenges of globalisation. The OECD is also at the forefront of efforts to understand and to help governments respond to new developments and concerns, such as corporate governance, the information economy and the challenges of an ageing population. The Organisation provides a setting where governments can compare policy experiences, seek answers to common problems, identify good practice and work to co-ordinate domestic and international policies.The OECD member countries are: Australia, Austria, Belgium, Canada, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Korea, Luxembourg, Mexico, the Netherlands, New Zealand, Norway, Poland, Portugal, the Slovak Republic, Spain, Sweden, Switzerland, Turkey, the United Kingdom and the United States. The Commission of the European Communities takes part in the work of the OECD.OECD Publishing disseminates widely the results of the Organisation's statistics gathering and research on economic, social and environmental issues, as well as the conventions, guidelines and standards agreed by its members. © OECD 2006 No reproduction, copy, transmission or translation of this publication may be made without written permission.

This book is published on the responsibility of the Working Group on Harmonisation of Regulatory Oversight in Biotechnology, which is a subsidiary group of the Chemicals Committee and Working Party on Chemicals, Pesticide and Biotechnology of the OECD. Foreword 3 FOREWORDGenetically engineered crops (also known as transgenic crops) such as maize, soybean, rapeseed and cotton have been approved for commercial use in an increasing number of countries. During the period from 1996 to 2005, for example, there was more than fifty-fold increase in the area grown with transgenic crops worldwide, reaching 90 million hectares in 2005.1 Such approvals usually follow a science-based risk/safety assessment.The environmental safety/risks of transgenic organisms are normally based on the information on the characteristics of the host organism, the introduced traits, the environment into which the organism is introduced, the interaction between these, and the intended application. The OECD's Working Group on Harmonisation of Regulatory Oversight in Biotechnology decided at its first session, in June 1995, to focus its work on identifying parts of this information, which could be commonly used in countries for environmental safety/risk assessment to encourage information sharing and prevent duplication of effort among countries. Biosafety Consensus Documents are one of the major outputs of its work.B...
