“…Hundreds of reference samples from provenance trials, herbaria or directly collected in the field were tested to develop this assay. A sampling and laboratory protocol was also developed to quantify and localize exotic individuals or components resulting from hybridization (e.g., Talbot et al 2012;Roe et al 2014). Such a method becomes an efficient way for companies to comply with forest certification standards by providing a precise measure of the invasiveness of the exotic species introduced into their plantations.…”

“…Such a method becomes an efficient way for companies to comply with forest certification standards by providing a precise measure of the invasiveness of the exotic species introduced into their plantations. Moreover, the localization and quantification of exotic gene dispersion improve the targeting and effectiveness of potential mitigation initiatives (Talbot et al 2012;Meirmans et al 2014). In poplars, the use of these molecular tools showed that the extent of exotic gene dispersion from plantations with exotic components depends on the recipient native species, the gender of novel varieties used for plantations, the size of natural surrounding native populations, and the environment in which they are found.…”

“…For instance, disturbed habitats (e.g., near-urban locations) appear more prone to exotics establishment than natural ones (Meirmans et al 2010;Thompson et al 2010). Moreover, male poplar varieties should be preferred to female trees since the exotic pollen coming from plantations is diluted in the native pollen cloud (Talbot et al 2012;LeBoldus et al 2013). Indeed these tools have helped demonstrate that effective monitoring and risk assessment is imperative to ensure that plantations with exotics do not threaten the genetic integrity of native forest trees or Canada's forest certification.…”

Consumers, retailers, investors, and governments want quality products that are both safe and obtained through legal and sustainable practices. The solution put into place to meet those challenges requires the implementation of a traceability system. In the context of forestry, traceability is the ability to inform about the identity or provenance of a wood product. The principle of traceability helps establish trust among the various stakeholders throughout the value chain. To this day, most traceability systems are based on paper permits, which are easier to falsify than systems that are based on genetic markers. In this manuscript, we define the elements of a traceability system based on genomic tools that could be useful for the Canadian forest sector. We also present several examples in which genomic tools are or could be used as traceability systems. Genomic tools and data happen to be available in quantity for several forest species and they could constitute the basis for the development of such traceability systems. Our aim is to demonstrate that there are actually great opportunities to develop such systems that could be applied to the Canadian forest sector.Keywords: traceability, genomic, markets, certification, sustainability, urban forestry, quality control, value chain, taxonomy, origin, database RÉSUMÉ:Les consommateurs, les détaillants, les investisseurs et les gouvernements veulent des produits de qualité, sécuritaires et qui résultent de pratiques légales et durables. Les principes de la traçabilité permettent de répondre à ces différents enjeux. Dans le contexte forestier, la traçabilité est la capacité d'informer sur l'identité ou la provenance d'un produit du bois. Ce principe aide à établir la confiance entre les différents acteurs de la chaîne de valeur. À ce jour, la plupart des systèmes de traçabilité sont basés sur des permis en papier qui sont facilement falsifiables. Dans ce manuscrit, nous définissons les élé-ments d'un système de traçabilité basé sur des outils génomiques qui pourrait être utile pour le secteur forestier canadien. Nous présentons aussi plusieurs exemples de la façon dont les outils de la génomique sont ou pourraient être utilisés. Des données et des outils génomiques sont actuellement disponibles en grandes quantités pour plusieurs essences forestières et ceux-ci pourraient constituer la base du développement de tels systèmes de traçabilité. Notre objectif est de démontrer qu'il y a actuellement de grandes opportunités pour développer de tels systèmes qui pourraient s'appliquer au secteur forestier canadien.

“…(Eckenwalder 1984;Floate 2004;Mahama et al 2011). Adding to this complexity, trihybrids (crosses involving three different species) and more complex combinations have been developed and deployed in Populus-breeding programs (e.g., Meirmans et al 2010;Talbot et al 2011) and have been detected in nature (Thompson et al 2010;Talbot et al 2012;Williams et al, unpublished). Molecular diagnostics, including AFLP (Cervera et al 2005), DNA sequencing (Hamzeh and Dayanandan 2004) combined with RFLP , microsatellites (Liesebach et al 2010), and mediumthroughput single nucleotide polymorphism (SNP)-based genotyping assays (Hamzeh et al 2007;Meirmans et al 2007; Thompson et al 2010;Talbot et al 2011) have been used to diagnose poplar species and hybrids with success.…”

Rapid identification of Populus L. species and hybrids can be achieved with relatively little effort through the use of primer extension-based single nucleotide polymorphism (SNP) genotyping assays. We present an optimized set of 36 SNP markers from 28 gene regions that diagnose eight poplar species (Populus angustifolia James, Populus balsamifera L., Populus deltoides Bartram, Populus fremontii Watson, Populus laurifolia Ledeb., Populus maximowiczii Henry, Populus nigra L., and Populus trichocarpa Torr. & Gray). A total of 700 DNA sequences from six Populus species (1-15 individuals per species) were used to construct the array. A set of flanking and probe oligonucleotides was developed and tested. The accuracy of the SNP assay was validated by genotyping 448 putatively "pure" individuals from 14 species of Populus. Overall, the SNP assay had a high success rate (97.6 %) and will prove useful for the identification of all Aigeiros Duby and Tacamahaca Spach. species and their early-generation hybrids within natural populations and breeding programs.Null alleles and intraspecific polymorphisms were detected for a few locus/species combinations in the Aigeiros and Tacamahaca sections. When we attempted to genotype aspens of the section Populus (Populus alba L., Populus grandidentata Michx., Populus tremula L., and Populus tremuloides Michx.), the success rate of the SNP array decreased by 13 %, demonstrating moderate crosssectional transferability.

Trees bearing novel or exotic gene components are poised to contribute to the bioeconomy for a variety of purposes such as bioenergy production, phytoremediation, and carbon sequestration within the forestry sector, but sustainable release of trees with novel traits in large-scale plantations requires the quantification of risks posed to native tree populations. Over the last century, exotic hybrid poplars produced through artificial crosses were planted throughout eastern Canada as ornamentals or windbreaks and these exotics provide a proxy by which to examine the fitness of exotic poplar traits within the natural environment to assess risk of exotic gene escape, establishment, and spread into native gene pools. We assessed postzygotic fitness traits of native and exotic poplars within a naturally regenerated stand in eastern Canada (Quebec City, QC). Pure natives (P. balsamifera and P. deltoides spp. deltoides), native hybrids (P. deltoides × P. balsamifera), and exotic hybrids (trees bearing Populus nigra and P. maximowiczii genetic components) were screened for reproductive biomass, yield, seed germination, and fungal disease susceptibility. Exotic hybrids expressed fitness traits intermediate to pure species and were not significantly different from native hybrids. They formed fully viable seed and backcrossed predominantly with P. balsamifera. These data show that exotic hybrids were not unfit and were capable of establishing and competing within the native stand. Future research will seek to examine the impact of exotic gene regions on associated biotic communities to fully quantify the risk exotic poplars pose to native poplar forests.
