  6. 4. Plants as Factories for Insect Pheromone Production : Deciphering and Reconstructing Sex Pheromone Biosynthetic Pathways of Female Moths

    Author : Yihan Xia; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pheromones biosynthesis; desaturases; elongases; reductases; plant factories;

    Abstract : Compared to other organisms in which the fatty acyl desaturases (FADs) are mostly involved in normal cellular lipid metabolism, moth FADs have evolved extent functions in the biosynthesis of sex pheromones. Female moths releasespecies-specific sex pheromones to attract conspecific males over a long distance for mating. READ MORE
