DOI: 10.1021/acs.jafc.2c02327
Abstract: As a highly efficient 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicide, topramezone is an ideal target for herbicide-resistant genetic engineering. In this study, two mutants, K-19 (N321Y) and K-63 (Q166R/E322V), with topramezone resistance increased by 205.3 and… read more here.

DOI: 10.3389/fpls.2018.01644
Abstract: Waterhemp [Amaranthus tuberculatus (Moq.) Sauer] is a problematic dicot weed in maize, soybean, and cotton production in the United States. Waterhemp has evolved resistance to several commercial herbicides that inhibit the 4-hydroxyphenylpyruvate-dioxygenase (HPPD) enzyme in… read more here.
