Abstract:
Oilseeds provide a renewable platform to produce lipids and other valuable biomolecules. While conventional crops accumulate a limited set of fatty acids, advances in synthetic biology now enable exogenous pathways to expand oil diversity. The oilseeds camelina (Camelina sativa) and pennycress (Thlaspi arvense) have emerged as powerful platforms for this work due to their efficient transformation methods. Recent breakthroughs have come from genome-editing rewiring of endogenous lipid metabolism to remove competing pathways, which, when combined with bioprospecting to identify more efficient enzymes, delivers the greatest gains in product yield. Overcoming challenges such as achieving cell-type-specific expression and developing scalable strategies for pathway gene expression control will ensure these crops realize their potential as versatile platforms for next-generation bioproducts.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

Factors Affecting Drug Biotransformation: Biological
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...
