Based on lumber prices, Western redcedar (Thuja plicata) is at times the highest prized forest tree species in Canada and with a yearly export of more than $ 770 million in 2006. T. plicata lumber is regarded as durable and rot resistant and therefore highly priced for special outdoor applications such as decking, furniture, roof and wall shingles. The rot resistance of trees and the related durability of generated lumber is primarily attributed to high levels of tropolones, antimicrobial compounds that accumulate in the heartwood. Tropolones purified from heartwood are also used in the medical/natural medicine/cosmetic market primarily in Asia because of their strong antimicrobial properties. Although rot resistance is a key trademark for T. plicata lumber, there is considerable variation for this trait in second-growth trees, and a significant portion of cut trees are culled because of considerable internal rot. There is also a similar variation in lumber durability. The genetic stock used for T. plicata production in Canada is produced by the British Columbia Ministry of Forests and range, our major partner in this project. These genetic stocks are in turn used for seed production primarily by our industrial partner Western Forest Products

根据木材价格，Western Redcedar（Thuja Plicata）有时是加拿大珍贵的森林树种，每年在2006年出口超过7.7亿加元。价格适用于特殊的户外应用，例如甲板，家具，屋顶和墙壁带状疱疹。树木的腐烂性和产生的木材的相关耐用性主要归因于高水平的TROPORONE，即积聚在心材中的抗菌化合物。从Heartwood纯化的Tropolones也主要用于亚洲医疗/天然医学/化妆品市场，因为它们具有强大的抗菌特性。尽管腐烂的阻力是T. plicata木材的关键商标，但对于二型树木中的这种特征有很大的变化，并且由于相当大的内部腐烂，因此将大部分砍伐的树木被剔除。木材耐用性也有类似的变化。我们在加拿大的Plicata生产的遗传库存是由我们在该项目中的主要合作伙伴的不列颠哥伦比亚省森林和范围生产的。这些遗传库存反过来主要由我们的工业合作伙伴西方森林产品用于种子生产
