Please address the information requirements listed in this section if the PNT was derived through recombinant DNA technology.
4.1 Transformation method:
4.1.1 Describe and provide references for the transformation method, e.g. Agrobacterium- mediated transformation or direct transformation by methods such as particle bombardment, electroporation, polyethylene glycol transformation of protoplasts, etc.
4.1.2 For direct transformation methods, describe the nature and source of any carrier DNA used.
4.1.3 For Agrobacterium-mediated transformation, provide the strain designation of the Agrobacterium used during the transformation process, and indicate if tumor-inducing genes were present on the plasmid-based vector, and whether Agrobacterium was cleared from the transformed tissue. Briefly describe or provide reference(s) describing the construction of the vector.
4.1.4 For transformation systems other than Agrobacterium, provide the following information:
4.2 Description of the genetic material potentially delivered to the recipient plant material (the modification/constructs):
4.2.1 Provide a summary of all genetic components which comprise the vector including coding regions,
and non-coding sequences of known function. Example of a table
describing the DNA components of a vector (from APHIS petition #94-257-01P) is available at
http://www.inspection.gc.ca/english/plaveg/
bio/usda/usda03e.shtml#table1. For each genetic component provide a citation where these functional sequences were
described, isolated, and characterized (publicly available database citations are acceptable) and indicate:
4.2.2 If there has been a modification in the transgene relative to the native gene that affects the amino acid sequence of the protein designed to be expressed in the plant, provide the citation. If the modified amino acid sequence has not been published, provide the complete deduced sequence highlighting the modifications. Indicate whether the modifications are known or expected to result in changes in post-translational modifications or sites critical to the structure or function of the gene product. An example of such modifications might include the addition of new glycosylation sites.
4.2.3 Provide a detailed map of the vector with the location of sequences described above that is
sufficient to be used in the analysis of data supporting the characterization of the DNA, including as appropriate the location of restriction sites and/or primers used

plasmid vector (from APHIS petition #94-257-01P)
is available at the following address: http://www.inspection.gc.ca/english/plaveg/
bio/usda/usda03e.shtml#figure
4.3 Characterization of the DNA inserted in the plant:
4.3.1 For all coding regions, provide data that demonstrate if complete or partial copies are inserted into the plant's genome. Coding regions may include truncated sense constructs, sequences engineered to be nontranslatable, antisense constructs, and constructs containing ribozymes, regardless of whether or not the coding region is designed or expected to be expressed in the transgenic plant. For allopolyploid plants, information may be required indicating into which parental genome insertion has occurred.
4.3.2 For noncoding regions associated with the expression of coding regions:
4.3.3 For non-coding regions which have no known plant function and are not associated with expression of coding regions:
4.3.4 Where appropriate, provide sequence data of the inserted material and of the surrounding regions (sequencing information may be informative in some cases, i.e., to fully characterize a partial or rearranged DNA insert).
4.4 Protein and RNA characterization and expression:
4.4.1 For all complete coding regions inserted, provide data that demonstrates whether the protein is or is not produced as expected in the appropriate tissues consistent with the associated regulatory sequences driving its expression (e.g., if the gene is inducible, determine if the gene is expressed in the appropriate tissues under induction conditions). For virus resistant plants where the transgenes are derived from a viral genome, in addition to transgene protein analysis, determine transgene RNA levels in tissues consistent with the associated regulatory regions driving expression of the transgene. The following exceptions also apply:
4.4.2 When a fragment of a coding region designed to be expressed in a plant is detected, determine whether a fusion protein could be produced and in which tissues it may be located.
4.4.3 Protein or RNA characterization may not be required for fragments of genetic constructs not expected to be functional in the plant (e.g., fragments of selectable marker genes driven by bacterial promoters.)
5.1 For plants which are either male or female fertile or both, provide data that demonstrates the pattern and stability of inheritance and expression of the novel traits. If the new trait can not be directly measured by an assay, it may be necessary to examine the inheritance of the novel DNA sequences directly, and expression of the RNA.
5.2 For plants which are either infertile or for which it is difficult to produce seed (such as vegetatively propagated male-sterile potatoes), provide data to demonstrate that the novel trait is stably maintained and expressed during vegetative propagation over a number of cycles that is appropriate to the plant.
In the case of an allopolyploid PNT, in which parental genome is the genetic modification?
8.1 Where applicable, characterize in detail the novel gene products, breakdown products, by-products and their metabolic pathways.
8.2 Is the novel trait expressed in a tissue-specific manner?
8.3 Is the novel trait expressed in a developmental stage-specific manner?
8.4 Is expression of the novel trait induced? If yes, what are the inducing agents?
8.5 Where applicable, describe the activity of the gene products, breakdown products and by-products in the host plant. Describe any changes to existing metabolic pathways (including altered accumulation and storage patterns), including those that might not be intended.
8.6 Where applicable, the toxicity of the novel gene products, breakdown products and by-products in the environment must be established. Describe:
1.1 Provide common name(s) and currently accepted scientific nomenclature.
1.2 A biology document describing the biology of the plant species must be submitted with the application if it is not available in the biology document series, unless the PBO confirms that such a document has previously been submitted.
Generally the most suitable counterpart for comparative studies is the isogenic line closest to the PNT, provided that the PNT is intended to be cultivated in the same region as this line. The counterpart may be a previously authorized PNT that has been in large-scale commercial production for several years. Developers are encouraged to consult with the PBO where there are questions regarding selection of an appropriate counterpart.
The applicant must provide information on the intended phenotype and any known unintended or unanticipated traits. The PNT should be compared to its counterpart(s) and related cultivated varieties as appropriate. If differences are detected, the applicant should address these findings in the application.
Typically, observations are made when the plants are grown in multiple sites and over more than one growing season. Confined research field trials of PNTs should take place in the intended growing region of the PNT in Canada. Data collected from field studies outside Canada can be used if the applicant demonstrates that the environment for testing the PNT is similar to the Canadian environment. In some cases, such as where there may be a potential for increased weed characteristics or if the plant is an outcrossing species, it may be appropriate to evaluate the plants outside of managed ecosystems. Depending upon the results, additional studies may be warranted to provide the required information. Applicants may provide valid scientific rationale why certain information is unnecessary or inappropriate.
3.1 Describe the breeding history of the PNT population being evaluated starting at the point of trait introduction.
3.2 Compare the PNT to its counterpart with respect to the following characteristics which influence reproductive and survival biology:
3.3 Compare the compositional analysis of the PNT to its counterpart(s) including, protein, lipids, fiber, and other parameters as appropriate. This data is used to assess secondary or pleiotropic effects and may indicate environmental impacts (e.g., changes in nutritional quality of seeds affecting birds).
3.4 Compare the PNT and its counterpart(s) with respect to levels of known naturally expressed toxicants, antinutrients and allergens known for that species.
4.1 Description of area of cultivation
4.2 Description of cultivation practices
Determine whether there are any sexually compatible species in areas where the PNTs will be grown. If there are, then this section is applicable and the following questions should be considered.
5.1 Which sexually compatible species, if any, are found in areas where the plant will be cultivated, including any new areas of cultivation?
5.2 Characterize the compatible wild relative(s) with respect to weediness in managed ecosystems and/or establishment and spread into natural ecosystems
5.3 In what ways would the introduced trait itself be likely to change the ability of the PNT to interbreed with other plant species?
5.4 In cases in which there is a potential for gene flow from the PNT into sexually compatible species (e.g. same or related species as appropriate), describe the consequences for the offspring of such crosses. Characterization of the crosses between wild relatives and PNTs should be considered using the criteria described in Section 1 above for PNTs in order to address questions 5.4.1) and 5.4.2) below.
6.1 Characterize the extent to which the gene product has been a part of the human or animal diet.
6.2 Where applicable, characterize to what extent the introduced DNA directly or indirectly leads to the expression or altered expression of a toxin or other product that is known to affect metabolism, growth, development, or reproduction of animals, plants, or microbes?
6.3 Consider potential physiological and behavioral effects to other organisms including insect, avian, aquatic, or mammalian species in the areas where the plant will be cultivated, including any new area of cultivation.
Consideration may be given to:
Consider levels and routes of exposure to all plant parts that express the gene, i.e., direct feeding or other exposure to the plant or plant part, dispersed plant parts, secretion, degradation, or leaching of the novel gene product, gene introgression, or organisms that have fed on the plant.
To address the possibility of persistent toxins in the environment or persistent changes in soil ecosystem function, applicants are encouraged to undertake residual effects studies. The residual effects of the PNT in comparison to the counterpart may be assessed by crop rotation studies or other techniques. Direct measurements in soil microbial communities may be indicated if microbial toxins are expected in root exudates.
6.4 Characterize potential adverse effects on the health of humans (including workers, adults, and children) which may arise through physical contact with or use of the PNT or its parts or its raw or processed products, other than for uses for which other authorizations or reviews are required (e.g. food, feed, pharmaceuticals). The analysis might include a comparison of the transgenic and non-transgenic counterpart(s) with respect to the likely exposure to toxins, irritants, and allergens.
In the case of PNTs developed using plant viral coding regions, address synergy, facilitated movement, transcapsidation, and viral recombination. For a description of these terms, see the OECD "Consensus Document on General Information concerning the Biosafety of Crop Plants Made Virus Resistant through Coat Protein Gene-Mediated Protection" No. 5, 1996, OCDE/GD(96)162 (http://www.olis.oecd.org/olis/1996doc.nsf/LinkTo/ocde-gd(96)162).
Biology Document
Have you confirmed with the PBO that a biology document has been prepared
for your species? (Note that biology documents used by the PBO are posted at
http://www.inspection.gc.ca/english/plaveg/bio/dir/biodoce.shtml as they are finalized). If not, have you enclosed a draft
biology document for your species, following those on the PBO web site as
an example? (See Section 7.2 of the Directive).
Core Characterization
Have you considered all the questions in Appendix 3?
Environmental Characterization
Have you considered all the questions in Appendix 4? Note that data from at least two seasons of trials in multiple
locations in Canada or in a similar environment are normally required to address these questions.
Detection and Identification
Have you provided a detection method capable of distinguishing your PNT
from other commercial cultivars of the same species? (See Section 7.4 of the Directive).
Food and Feed Use Approvals
If your PNT is intended for food and/or feed use, have you applied to the
Novel Foods Section, Health Canada and/or the Feed Section, CFIA
for food and/or feed use approval as appropriate? (See Section 8.2 of the Directive).
Special Crop Management Considerations
If your PNT carries a novel insect resistance, have you provided an
appropriate Insect Resistance Management (IRM) plan (Please see Section 7.5.1 of this Directive)? If your PNT carries a novel herbicide tolerance, have you provided an appropriate Herbicide
Tolerance Management (HTM) plan? You are encouraged to work with
seed distributors, extension personnel and growers to develop and implement an appropriate HTM plan for your PNT (Please see Section 7.5.2 of this Directive).
Please note that the PBO's decision with regards to authorizing the environmental release of a PNT expressing either a novel insect resistance or a novel herbicide tolerance, will take into consideration whether or not the applicant has provided a stewardship plan addressing the need for the responsible deployment of the novel crop in question into the environment.
Post-Release Monitoring Plan
You must provide a general plan for post-release monitoring of environmental effects of your PNT (see Section 7.6 of the Directive).
Payment
Have you enclosed the application fee, according to the guidelines provided
in http://www.inspection.gc.ca/english/plaveg/bio/feepaie.shtml? Please note that review of your application may not begin
until your payment has been received.
