Newswise — A research team has elucidated the biosynthetic pathways of pyrethrum ( Tanacetum cinerariifolium ), identifying key genes responsible for pyrethrin production. These findings highlight pyrethrum's multifaceted chemical defenses and its potential as a companion plant in agriculture. This research paves the way for future studies to enhance sustainable farming practices by integrating pyrethrum's natural defense mechanisms.
Insect pests cause up to 35% of crop yield losses globally, leading to the extensive use of synthetic chemical pesticides, which harm the environment and human health. Recent research has focused on eco-friendly natural pyrethrin from T. cinerariifolium , which is effective and safe but declined in use post-World War II due to cheaper synthetic pyrethroids.
Despite a resurgence in pyrethrin use, understanding the biosynthetic pathways and regulatory mechanisms of pyrethrin production remains crucial. A review article (DOI: 10.48130/opr-0024-0013) published in Ornamental Plant Research on 03 June 2024, explores the historical use of pyrethrum, reveals the biosynthetic pathways and the majority of genes responsible for pyrethrin production, highlights its antifungal sesquiterpene lactones and aphid-repelling pheromones, and emphasizes the need for further research on pyrethrum's defense strategies for sustainable farming practices.
This review delves into the historical use and cultivation of pyrethrum, highlighting its insecticidal properties re.
