Abstract A population of common ragweed from Delaware was not controlled in the field by herbicides that inhibit acetolactate synthase (ALS) or protoporphyrinogen oxidase (PPO). Research was conducted to ascertain if this population was resistant to these herbicidal modes of action and, if so, to determine the resistance mechanism(s). Resistance was confirmed by dose-response studies on greenhouse-grown plants with multiple ALS- and PPO-inhibiting herbicides. DNA sequence data revealed that…

INHERITANCE OF RESISTANCE TO PROTOPORPHYRINOGEN OXIDASE INHIBITOR HERBICIDES IN WILD POINSETTIA
- 2016
Weed resistance to herbicides is a major global problem for agriculture. In recent years, the increased use of herbicides, without proper planning, has led to a large increase in the number of cases…

Multiple Resistance to PPO and ALS Inhibitors in Redroot Pigweed (Amaranthus retroflexus)
- BiologyWeed Science
- 2019
This study confirms the first case of multiple resistance to PPO and ALS inhibitors in A. retroflexus and determines that the target-site resistance mechanism was produced by Ala-205-Val and Arg-128-Gly mutations in the ALS gene and PPX2 gene, respectively.
Resistance to Fomesafen, Imazamox and Glyphosate in Euphorbia heterophylla from Brazil
- BiologyAgronomy

This is the first characterisation of multiple resistance to these three groups of herbicides in E. heterophylla in the world and shows the participation of CytP450 in fomesafen resistance, but a molecular mechanism could also be involved.
Two new PPX2 mutations associated with resistance to PPO-inhibiting herbicides in Amaranthus palmeri.

It is concluded that strain VSR751 must be defective in protoporphyrinogen oxidase (PPO), the product of the hemG gene, which is consistent with the previous report that the mammalian PPO had the flavin cofactor.
