Plant nursery techniques have been developed intensely not only for food production, but also for gardening and indoor plants. The plant nursery business is booming with current high demand for indoor plants in homes, offices and public spaces. Currently, Canadians are importing many different plant species from all over the world and are propagating them to meet an ever increasing demand. According to Statistics Canada, in 2013 the Canadian Greenhouse Industry produced a combined 14,700,000 plants of Chrysanthemums and Kalanchoes (the two leading indoor flowering plants). Introduction of a new plant that will compete in the same marketplace as Chrysanthemum and Kalanchoe can breathe new life into the potted indoor plant market in Canada. Even at a mere 10% of the market of these plants, it would equal 1, 470,000 plants. In addition, importing seeds/seedlings continuously from other countries will have a significant risk for environmental contamination (microorganisms and unwanted foreign plant species) in addition to the cost associated with import and safety regulations. To seek cost-effective and sustainable ways to propagate commercially valuable plants in Canada, the Canadian plant nursery company, Valleyview Gardens has established a plant tissue culture facility for in vitro propagation. Recently they have succeeded in generating viable callus tissue of Michelia alba (White Sandalwood) which is a commercially important woody plant. The next step, the regeneration of whole seedling from this callus, is challenging and requires assistance from plant tissue culture specialists. The Yoshioka laboratory at the University of Toronto has extensive expertise in plant tissue culture and is fully-equipped with all infrastructure necessary for this challenge. Thus, we will collaborate for the regeneration of plants from the M. alba callus. The anticipated established method can be applied to other commercially important woody plants and this will provide a significant advantage to the Canadian plant nursery business as well as maintain Canadian environmental safety. The outcome is also scientifically important as it may advance woody plant tissue culture, which is currently difficult for many tree species.

植物苗圃技术不仅在粮食生产方面得到了大力发展，而且在园艺和室内植物方面也得到了大力发展。目前，家庭、办公室和公共场所对室内植物的需求很高，苗圃业务正在蓬勃发展。目前，加拿大人正在从世界各地进口许多不同的植物物种，并进行繁殖，以满足不断增长的需求。根据加拿大统计局的数据，2013年加拿大温室产业共生产了1470万株菊花和kalanies（两种主要的室内开花植物）。引进一种新的植物，将在同一市场上与菊花和kalanche竞争，可以为加拿大的室内盆栽植物市场注入新的活力。即使只占这些植物市场的10%，也相当于147万株。此外，除了与进口和安全法规相关的成本外，持续从其他国家进口种子/幼苗将面临环境污染（微生物和不需要的外来植物物种）的重大风险。为了在加拿大寻找具有成本效益和可持续发展的方法来繁殖具有商业价值的植物，加拿大植物苗圃公司Valleyview Gardens建立了一个植物组织培养设施，用于体外繁殖。最近，他们成功地培育出了一种具有重要商业价值的木本植物——白檀香的愈伤组织。下一步，从这个愈伤组织再生整个幼苗，是具有挑战性的，需要植物组织培养专家的帮助。多伦多大学的吉冈实验室在植物组织培养方面拥有广泛的专业知识
