Terpenoid Aroma Metabolism in Specialty Food Crops

Plants produce a wealth of volatile organic compounds (VOCs) that contribute to pollinator attraction, interorganismal interactions and defense. We perceive these VOCs as fruit and flower scents and aromas. To better understand the diversity of terpenoids to aroma and environmental interactions and provide resources for breeders and growers toward improving crop quality and resilience traits, we currently investigate terpenoid aroma metabolism in strawberry and Christmas trees.

A GIFT SEED: Accelerated Genetic Improvement of Fir Through Sequencing, Economics, Extension, & Diagnostics  

Many types of conifers are used as Christmas trees, but true firs (Abies spp.) are the most popular, comprising 66% of all sales. The most popular Christmas trees are Fraser fir (Abies fraseri) and noble fir (A. procera) which account for half of all real trees sold as part of the $2.5 billion annual real Christmas tree industry. However, warming climates threaten productivity of Fraser and noble fir in the US. This project aims to genetically improve fir species by (1) enhancing climate resilience; (2) enhance disease and pest resistance; and (4) develop new technologies to reduce production costs, improve safety, reduce labor, and improve the environmental benefits of real trees through sustainability.
