Abstract excerpt
BACKGROUND: Amaranthus tuberculatus (waterhemp) is a major agricultural weed known for its rapid evolution of resistance to multiple herbicide modes-of-action. Resistance to 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors such as mesotrione is particularly concerning, yet the underlying genetic and molecular mechanisms remain incompletely understood. This study investigated the basis of mesotrione...
