Floral scent biochemistry in plants

The production of floral scents is a sophisticated biochemical process that significantly influences plant-pollinator interactions. Floral scent profiles are composed of various volatile organic compounds (VOCs), synthesized through several metabolic pathways, including the terpenoid and phenylpropanoid pathways. Enzymes such as terpene synthases and phenylalanine ammonia-lyase are critical in determining the types of scents produced. Factors such as environmental conditions, plant health, and developmental stages can alter the scent composition, affecting pollinator attraction. By exploring the biochemical pathways behind floral scent synthesis, researchers can enhance breeding programs aimed at improving the fragrance of crops, thereby boosting pollination and fruit yield.
