Subgenomic Distribution and Herbicide Cross‐Resistance of ALS Gene Mutations in Allohexaploid Echinochloa crus‐galli [PDF]

Plant Direct
Herbicide target site resistance in polyploid species is more complex than in diploids due to potential subgenome interactions. This study characterized mutations in the ALS gene across distinct subgenomes of hexaploid Echinochloa crus‐galli and ...

De Novo Design and Synthesis of Novel Benzoxazinone Derivatives Targeting Dihydroxyacid Dehydratase. [PDF]

Plant Biotechnol J
ABSTRACT Dihydroxyacid dehydratase (DHAD), a key enzyme in the branched‐chain amino acid (BCAA) synthesis pathway, is a promising herbicide target. Currently, no commercial herbicides target DHAD, and no inhibitors are in development. Structural analysis suggests that coordination with iron–sulfur clusters and hydrophobic interactions with Tyr215 and ...

Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism. [PDF]

Plant Direct
ABSTRACT Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate. The transfer of electrons to the P450 active site in the P450 catalytic site relies on a robust and intricate CPR:P450 complex in the endoplasmic reticulum membrane.
