As a general trend, research activities related to biotechnology in the Canadian Forest Service (CFS) have increased significantly during the last decade as illustrated by a marked increase in resources committed to this field and in the number of publications produced by the scientists involved. The three areas covered by CFS biotechnological activities are forest regeneration, forest protection and environmental impact assessment. In forest regeneration, the tissue culture of conifers using somatic embryogenesis is a good example of potential application of biotechnology to conventional tree improvement. This technology is being used on a large scale in British Columbia and involves private firms such as BC Research Inc. Other technologies are also being developed such as genetic engineering which eventually will allow the incorporation of advantageous traits into trees which would otherwise be difficult or impossible to achieve. In forest protection, Bacillus thuringiensis is a well known success of biotechnology. This bacterium is used as a biopesticide in Canada to control spruce budworm and gypsy moth. Its use has been increasing during the last few decades and, with the phasing out of chemical insecticides for forestry use, Bacillus thuringiensis will become one of the few alternatives available for insect control. Insect viruses are also becoming more attractive for the biological control of forest pests. The CFS has registered three viruses for forestry use and the next generation of viruses will be genetically engineered to increase their efficiency and effectiveness. The last area of activity encompasses environmental impact studies of biotechnology products for forestry use. The CFS has been a pioneer in the development of microcosms (soil and aquatic) for studying microbial pesticides used to evaluate the impact of engineered biopesticides. Key words: biotechnology, genetic engineering, biopesticides, molecular biology, tissue culture, microcosm, regulation, environmental impact

Abstract The Third Revolution—the application of molecular biology to plant improvement—is providing biotechnology for Pinus taeda breeding programs in the southern United States. To harness commercial value, forest biotechnology must be integrated with pine breeding. Overlaying an agriculture biotechnology template on any aspect of forestry ignores key historical, economic and biological factors unique to pine breeding programs and even to biotechnology applications. Understanding differences between forestry and agriculture will aid policy decisions about the use of genetically enhanced pines and identify numerous leverage points for directing forest biotechnology research toward commercial advantage. Integrating biotechnology into a P. taeda breeding program is illustrated using a case study approach. A molecular marker system is proposed for improving the selection efficacy of a pine breeding program. South. J. Appl. For. 25(3):116–121.

This paper discusses the potential risks and benefits that may be derived from present and future use of forest biotechnology in Canada. The complementary use of forest biotechnology along with traditional silvicultural programs has the potential to improve the quality of Canadian forests by promoting: increased forest productivity, a reduction of exploitation pressure on forest lands, an increase in gene conservation, and improved forest management. However, these benefits could also be followed by undesirable effects such as pest adaptation to control methods, non-target pest emergence, reduction of biodiversity, and genetic pollution. Measures that could be implemented to circumvent these potentially undesirable effects are discussed. Such measures should be based on a sound understanding of the ecological effects of biotechnology and should promote biotechnology use within programs of integrated forest management.

Annotation:

The importance of forest ecosystems for ecological balance and as a reservoir of genetic heritage and biodiversity is evident, the need for conservation is further exalted by the great anthropic pressure suffered by these ecosystems due to the increasing demand of the forest sector. The possibility of using biotechnological practices to combine conservation with sustainable economic development emerges as a promising alternative for the recovery and use of forest species, especially those threatened with extinction. The aims of the article is to demonstrate the main aspects of Forest Biotechnology with regard to conservation and the continuity of the supply of the demand of the economic sector. The central role of wood in economic development has led to the intense exploitation of forest ecosystems, which has resulted in the loss of biodiversity and reduced capacity to meet the demands of the sector. The tools of forest biotechnology, when employed in the optimization of conservation, allow a compatibilization with commercial production, acting as instruments of sustainable development. Forestry Biotechnology acts as an instrument to reconcile conservation with economic development, including forests at the heart of a strategy for a sustainable future.

The Canadian forest sector is at a critical juncture in maintaining its competitive position internationally. One reason is the difficulty that we are experiencing in holding the line on the costs of timber and its processing. The expenditure on silviculture alone is often in the range of 10-20% of the cost of delivering roundwood to manufacturing plants. The entire forest community is counting of forestry science, and especially biotechnology, to enhance industry viability and provide solutions to problems with environmental quality. However, the funding of forestry R&D has always been handicapped by our inability to argue persuasively for science budgets. The central theme of this paper is that the application of biotechnology and other science to forestry certainly does pay. A synthesis of traditional and newer approaches to benefit-cost analysis is recommended to assist science managers in making their case for financial support.

Abstract Woody plants have been cultured in vitro since the 1930s. After that time much progress has been made in the culture of tissues, organs, cells, and protoplasts in tree species. Tree biotechnology has been making strides in clonal propagation by organogenesis and somatic embryogenesis. These regeneration studies have paved the way for gene transfer in forest trees. Transgenics from a number of forest tree species carrying a variety of recombinant genes that code for herbicide tolerance, pest resistance, lignin modification, increased woody bio-mass, and flowering control have been produced by Agrobacterium-mediated and biolistic methods, and some of them are undergoing confined field trials. Although relatively stable transgenic clones have been produced by genetic transformation in trees using organogenesis or somatic embryogenesis, there were also unintended unstable genetic events. In order to overcome the problems of randomness of transgene integration and instability reported in Agrobacterium-mediated or biolistically transformed plants, site-specific transgene insertion strategies involving clustered regularly interspaced short palindromic repeats (CRISPR-Cas9) platform offer prospects for precise genome editing in plants. Nevertheless, it is important to monitor phenotypic and genetic stability of clonal material, not just under greenhouse conditions, but also under natural field conditions. Genetically modified poplars have been commercialized in China, and eucalypts and loblolly pine are expected to be released for commercial deployment in USA. Clonal forestry and transgenic forestry have to cope with rapid global climate changes in the future. Climate change is impacting species distributions and is a significant threat to biodiversity. Therefore, it is important to deploy Strategies that will assist the survival and evolution of forest tree species facing rapid climate change. Assisted migration (managed relocation) and biotechnological approaches offer prospects for adaptation of forest trees to climate change.

Although the two current high profile scientific fields of biotechnology and biodiversity have extremely different scientific foundations and philosophies, they are still closely interrelated. Useful forest biotechnology is dependent on the availability and maintenance of a broad genetic foundation. Such a foundation is best achieved over time by maintaining the biological diversity of natural systems. In contrast, it is conceivable that with the release of genetically engineered organisms, natural biological diversity could be negatively impacted. The possibility of such an influence will be discussed. Finally, the politics of the relationship between these two emerging scientific fields will be briefly reviewed.

In the article substantiates that development of forest complex of the Russian economy is not possible without the implementation of structural reforms and emphasis on diversification of forestry as an important industry segment. Reasons for diversification of forest complex are shown, including: disparities in development of technological chain - forestry-logging-woodworking; technological, territorial and economic fragmentation of forest, harvesting and processing enterprises and industries; infrastructural and economic barriers; low level of Research and Advanced Development and industrial innovation at all stages of technologically related industries. It is proved that diversification of forestry should be carried out at the level of the most significant sub-systems: reforestation and afforestation in order to transfer to the technologies allowing reducing the period of growing of wood and target assortments. Diversification of forestry is possible during the transition from forest crops to plantation afforestation through the establishment of industrial forest plantations on the lands of forest fund. To reduce the risk component in the diversification of forest production, creation of industrial forest plantations must be carried out not far from industrial consumers of wood, which will ensure the economic feasibility of growing, harvesting and delivery of wood raw material. The proposed mechanism of diversification in combination with biotechnology will provide increasing demand for timber, with significant reduction of the environmental load on natural forest stands, allowing you to preserve natural ecosystems for purposes of recreation. Introduction of biotechnology in forestry will reduce the gap in development segments of the forest complex and increase wood supply for diversified industries. Diversification of forestry and development of industrial plantation afforestation is constrained by legal framework and absence of measures of financial support of enterprises of forest complex.

Forest genomics is a relatively recent research field and is often poorly understood both by the public and forest managers. Genomics in forestry, an expansion of forest biotechnology, seeks to develop generalized technologies for use in industrial plantations and/or natural forests as well as within process optimization, product development and international trade facilitation. With such tools it is possible to address formerly intractable issues such as understanding the underpinnings of complex traits for conservation management purposes, improved use of forest trees as carbon sinks, feedstock for biofuels and “green chemistry” through deeper understanding and effective utilization of forests’ natural variation. Diverse end-users could benefit from genomics tools; for example, real-time detection and mapping of known and novel pathogens along with risk assessments to protect forest nurseries and natural forests from invasive pathogens and reduce economic losses associated with diseases. Since 2001, there has been approximately $123 million invested in Canadian forest genomics research; we thought it would be helpful to summarize projects in Canada and the USA and to identify research priorities and potential economic implications by: (a) developing a robust typology of forest sector genomics research relevant to Canadian application; (b) categorizing each initiative for its application potential (commercial, noncommercial); and, (c) demonstrating with silvicultural gain, insect resistance, and wood composition themes the application of modeling and economic analysis.

Abstract In this review we examine the history and progression of conifer genetic engineering. The review includes the methods used, the conifer species transformed, the genes inserted and the regeneration of genetically engineered conifer trees. We cover both Biolistic® and Agrobacterium-mediated transformation, and we detail transformation events with and without plant regeneration. We show that almost all conifer transformation work uses nptII as a selective marker, and very often uidA is included as a reporter gene. Further, we show that a range of genes that are of commercial interest for forest tree plantations have been introduced, such as herbicide resistance, insect resistance and those related to wood properties. We briefly discuss the future for biotechnology in the context of socially acceptable enhanced plantation forestry and under consideration of benefits and risks.

This paper presents an overview of the results achieved in the laboratory for molecular studies of the Institute of Lowland Forestry and Environment, University of Novi Sad, in the field of biotechnology, mainly in molecular genetics, genomics and functional genomics. Researches are designed to serve as a breeding tool. The aim was to clarify the processes of classical genetics by applying modern methods and enable a qualitative and rapid progress in understanding the processes that occur at the level of genes in the genome of forest plant species and thus help the processes of conservation of valuable taxa at the time of global climate change. The results are presented within various research fields and by type of forest trees that were given priority by importance in forest ecosystems. Studies have in most cases been of applicative character with the aim of solving the major problems in forestry, but also of fundamental nature when they were necessary to elucidate the response of forest species to the induced stress, which is an inevitable component of the time characterized by tolerance and adaptation as keywords.

AbstractLeuce-poplars are a native stand-forming tree species throughout Hungary. Several species or selections of them are used as ornamental plants in parks or to line streets and highways. They cover approximately 4.0 per cent of the total forested area in Hungary (70000 ha). The white (grey) poplar belongs to the Leuce poplars and plays a significant role in sand fixation, regional forestation, and nature conservation. The National Agricultural Research and Innovation Centre, Forest Research Institute or NARIC-FRI (formerly known as the Forest Research Institute) is involved in long-term breeding work for the selection of fast-growing white poplar trees under dry conditions. In vitro multiplication of trees is applied mainly to fruit growing trees in Hungary; in forestry research it is used primarily for selective breeding. This paper presents a short overview of the most important issues concerning the biotechnology of different Populus species, the related research on micropropagation trials, and the results of field investigations of micropropagated Leuce-poplar clone experiments.

Poplars (genus Populus) have emerged as a model organism for forest biotechnology, and genetic modification (GM: asexual gene transfer) is more advanced for this genus than for any other tree. The goal of this paper is to consider the benefits expected from the use of GM poplar trees, and the most significant claims made for environmental harm, by comparing them to impacts and uncertainties that are generally accepted as part of intensive tree culture. We focus on the four traits with greatest commercialization potential in the near term: wood modification, herbicide tolerance, insect resistance, and flowering control. After field trials and selection of the top performing trees, similar to that during conventional poplar breeding, GM poplars appear vigorous and express their new traits reliably. The ecological issues expected from use of GM poplars appear similar in scope to those managed routinely during conventional plantation culture, which includes the use of exotic and hybrid genotypes, short rotations, intensive weed control, fertilization, and density control. The single-gene traits under consideration for commercial use are unlikely to cause a significant expansion in ecological niche, and thus to substantially alter poplar's ability to "invade" wild populations. We conclude that the ecological risks posed by GM poplars are similar in magnitude, though not in detail, to those of routine poplar culture. We also argue that the tangible economic and environmental benefits of GM poplars for some uses warrant their near-term adoption—if coupled with adaptive research and monitoring—so that their economic and ecological benefits, and safety, can be studied on commercially and ecologically relevant scales. We believe that the growing demand for both wood products and ecological services of forests justifies vigorous efforts to increase wood production on land socially zoned for tree agriculture, plantations, or horticulture. This is the key reason for poplar biotechnology: the combination of economic efficiency with reduction of farm and forestry impact on the landscape.

Annotation:

Time is a major constraint in the progress of tree improvement programs. Four ways in which time influences the tree improvement process are (i) evolutionary time, (ii) time to harvest, (iii) time to achieve phenotypic stability, and (iv) time to reach reproductive maturity. The ways in which each of these affects the three phases of a tree improvement program (conservation, selection and breeding, and propagation) are identified and discussed. How biotechnological techniques, as well as other enabling technologies, address the time constraint problem is also discussed. The biotechnological approaches include tissue culture, molecular genetics, and genetic engineering; the enabling technologies include early testing and flower induction. Through tissue culture it is possible to increase genetic gain per unit time and increase total genetic gain by using more of the total genetic variation. Development of high-resolution linkage maps, through application of molecular genetics technology, will provide new approaches to early screening, testing, and selection. Additionally, molecular probes will be useful in improving methods that genetically fingerprint germ plasm. Genetic engineering has considerable potential to reduce time constraints. However, because of the diverse breeding and production populations typically employed, much basic work needs to be done to integrate genetically engineered materials into tree improvement programs. Early selection and flower induction address the time constraints imposed by age-stable performance and reproductive maturity. When used in combination with the previously described biotechnologies, a powerful system is created that can dramatically reduce the time required to integrate genetically improved material into forest regeneration programs. An example of integrating tree improvement, clonal forestry, and biotechnology is described for an existing black spruce regeneration program.

Annotation:

Agricultural biotechnology plays a key role in research tools that scientists use to understand and manipulate the genetic makeup of organisms for use in agriculture: crops, livestock, forestry and fisheries. Biotechnology has vast application than genetic engineering; it also includes genomics and bioinformatics, markers-assisted selection, micropropagation, tissue culture, cloning, artificial insemination, embryo transfer and other technologies. However, genetic engineering, mainly in crop sector, is the area in which biotechnology is most directly affecting agriculture in developing countries and in which the most vital public concerns and policy issues have arisen. Therefore, this review report tries to touches all the aspect of biotechnology in the field of agriculture.
