Uridine-5'-tri-phosphate is a candidate component of the soluble sex pheromone bouquet in a marine shrimp, Lysmata wurdemanni (2020)
Journal Article
Zhang, D., Liu, X., Harley, M. A., & Hardege, J. D. (2020). Uridine-5'-tri-phosphate is a candidate component of the soluble sex pheromone bouquet in a marine shrimp, Lysmata wurdemanni. Marine ecology progress series, 640, 139-146. https://doi.org/10.3354/meps13294

Characterisation of distance sex pheromones in decapods is challenging, although great efforts have been made in this field in the past 50 yr. In a previous study, we identified a component of the distance (soluble) sex pheromone bouquet of the peppe...
