19、tically modified plants is tested in an experimental field, it is important that a valid monitoring strategy is used, and that the monitoring strategy has been designed in accordance with the specific plant species and experimental requirements. In this European Standard, monitoring refers both to t

20、he monitoring of the occurrence, persistence and/or spread of the genetically modified plant and/or the gene(s) involved in the modification. This European Standard is intended to aid the experimenter in the design of a monitoring strategy appropriate to the monitoring objectives. Therefore, this Eu

21、ropean Standard gives the experimenter a list of points that should be considered in determining the validity of a monitoring strategy comprising valid design, review, execution and documentation of a monitoring protocol. 1 Scope This European Standard gives guidance on factors and criteria consider

22、ed for the determination of the suitability and validity of the design, development and execution of a monitoring strategy for genetically modified plants. Monitoring encompasses detection of genes and traits, as well as the identification of genetically modified plants in an experimental release. T

23、his European Standard provides the person conducting a monitoring programme with factors and criteria that should be considered in determining the validity of the proposed monitoring strategy. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from o

24、ther publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment

25、or revision. For undated references the latest edition of the publication referred to applies. EN 12305 Biotechnology Modified organisms for application in the environment Guidance for the sampling strategies for deliberate releases of genetically modified plants 3 Definitions For the purposes of th

26、is standard, the following definitions apply. 3.1 analyte substance sought or determined 3.2 behaviour interaction of the organism(s) with abiotic and biotic environments, its (their) occurrence, persistence, multiplication and spreading abilities 3.3 control preparation of known characteristics use

27、d to standardize an analysis 3.4 detection recognition of the presence of an organism or of a molecular structure within a sample 3.5 experimental field area within a release site which contains the plots necessary to standardize the analysis 3.6 genetic modification of interest conceptual design fo

28、r altering the genetic material within an organism NOTE 1 The genetic modification of interest can be described at different levels of molecular detail. NOTE 2 The conceptual design can include insertion, substitution or deletion of genetic material. 3.7 genetically modified plant plant in which the

29、 genetic material has been altered in a way that does not occur naturally by mating and/or natural recombination NOTE Within the terms of this definition genetic modification occurs at least through the use of the techniques listed in the Directive 90/220/EEC or its appropriate annexes (see annex B

30、2). 3.8 identification establishment of identity by comparison with a reference NOTE 1 The reference could be an organism, a molecular structure or the genetic modification of interest. NOTE 2 The certainty of identification can be affected by the types and/or number of characteristics investigated.

34、 site. The design and execution of a valid monitoring strategy is therefore dependent on the particular objectives of the monitoring strategy. These can include the following. a) Studies on the effect of the genetic modification of interest on the behaviour of the genetically modified plants release

35、d into the environment. The monitoring strategy can include studies on the presence of the genetically modified plant of interest in environmental samples, its performance in the environment and of its effects on the ecosystem considered. b) Studies on the functioning of the genetic modification in

36、the genetically modified plants released into the environment. The monitoring programme can include studies on the molecular stability and functional expression of the gene(s) involved in the genetic modification of interest. c) Studies on the transfer of the gene(s) involved in the genetic modifica

37、tion of interest. The monitoring programme can include studies on transfer to the indigenous plant population cultivated or not. 5 Monitoring strategy 5.1 General It is first necessary to determine the objectives of the monitoring strategy. The main steps in the development of the monitoring strateg

38、y are: a) design and review of the monitoring protocol; b) validation of the monitoring protocol; c) execution of the monitoring protocol; d) appropriate record keeping. Responsibility for these steps should be assigned to a specific authority, organization or person. The monitoring strategy should

39、be reviewed regularly, in the light of the field inspections, to ensure its continuing validity. 5.2 Criteria for the design of the monitoring protocol The following key factors should be considered in the initial design of the protocol to ensure the design correlates with the monitoring strategy ob

40、jectives as determined by the person designing the test: a) sampling strategy appropriate to the objectives and needs of the monitoring strategy as described in EN 12305; NOTE The development of a valid monitoring and sampling strategy for deliberate releases of genetically modified plants in the en

41、vironment is summarized in Figure A.1. b) extent of monitoring necessary to fulfil the requirements of the experiment such as timescale, scale and area of sampling; c) plant species, predicted behaviour of plant, particularly with respect to pollination and pollen dispersal, seed dispersal, dispersa

42、l by vegetative means, competitive ability and weediness; d) relevant area for monitoring in line with the monitoring objectives such as the release site and/or the potential dispersal area; e) particular features of the release site to monitor such as adjacent sites, streams, soil movement activiti

43、es, meteorological parameters, wild relatives; f) appropriate choice of methods used for monitoring with respect to plant species involved in experiments. 5.3 Validity of the design of the monitoring protocol 5.3.1 General Factors and criteria which should be considered for the determination of the

44、suitability and validity of a monitoring protocol are given in 5.3.2 to 5.3.5. These should not be considered as exhaustive lists. 5.3.2 Considerations with respect to fulfilling the overall experimental objective In fulfilment of the overall experimental objective, the aim of individual experiments

45、 can be: detection; identification; determination of the molecular stability of the gene expression; determination of the effect of the modification; rapid screening or detailed investigation; quantitative or qualitative approach.Page 5 EN 12468:1997 BSI 1998 5.3.3 Considerations with respect to the

46、 genetic modification The factor(s) being monitored can be one or a combination of the following: gene presence; gene expression; presence of genetically modified plant; behaviour of the genetically modified plants in the environment. 5.3.4 Considerations with respect to the release site Factors inf

47、luencing the monitoring strategy with respect to the release site can be: environmental conditions; presence of organisms which feed on the plant; presence of organisms that can serve as carriers for genetic material; presence of compatible species within a potential dispersal area. 5.3.5 Considerat

48、ions with respect to the validity of methods used for monitoring 5.3.5.1 Key considerations with respect to the validity of methods used for monitoring The following parameters should be considered for method validation to ensure that the performance characteristics of the method(s) are understood,

49、and to demonstrate that the method used for monitoring is scientifically sound and valid under the experimental conditions to which it is applied: fit for purpose; selectivity; specificity; reproducibility; repeatability; reliability; feasibility; limitations; detection limit; access to appropriate controls. NOTE A full definition of several of these parameters is given in Eurachem guidance document n1 - 1993 (see annex B 5). The following explanations are intended as a
