What is Metabolic Engineering Plant Volatiles?

Metabolic engineering of plant volatiles redirects metabolic flux in plants toward volatile organic compounds (VOCs) like terpenoids and phenylpropanoids to enhance emission for pollinator attraction, defense, and commercial applications.

Researchers use CRISPR, synthetic pathways, and overexpression to boost VOC production in planta. Key pathways include terpenoid synthases and phenylpropanoid metabolism. Over 10 high-citation papers, led by Dudareva et al. (2013, 1553 citations) and Chen et al. (2011, 1378 citations), detail biosynthesis and engineering strategies.

Key Challenges

Why It Matters

Engineered plant volatiles improve crop resilience against drought and herbivores, as shown by Nakabayashi et al. (2013) overaccumulating flavonoids for oxidative tolerance (1335 citations). They enhance fruit flavors for agriculture and perfumery, with Dudareva et al. (2013) linking VOCs to pollinator attraction and pathogen defense (1553 citations). Commercial impacts include aroma modulation in wine via microbial influences (Swiegers et al., 2005, 1134 citations) and scalable fragrance production.

Key Research Challenges

Flux Competition in Pathways

Redirecting precursors from primary metabolism to VOCs competes with essential processes like growth. Dudareva et al. (2013) note terpenoid engineering often reduces non-volatile outputs. Synthetic pathway integration requires balancing enzyme kinetics (Chen et al., 2011).

Volatilome Emission Control

Engineered VOCs must emit at optimal rates without toxicity or loss to non-target sinks. Tholl (2015) highlights terpenoid synthase diversification challenges in emission profiles. Dudareva et al. (2006) report 1700+ volatiles needing precise regulation (1330 citations).

CRISPR Off-Target Effects

Genome editing for synthase genes risks unintended mutations affecting development. Dong and Lin (2020) detail phenylpropanoid pathway sensitivity to edits (1449 citations). Verification of stable, high-emitting lines remains labor-intensive.
