Special Issue Information

Dear Colleagues,

Weeds are a kind of biotic threat to agricultural production, causing crop yield losses and health hazards, and impairing product quality. Herbicides are one of the most effective ways to control weeds; however, relying heavily on herbicides results in the development of resistance. To clarify the mechanism of weed resistance to herbicides, it is very important to develop a rapid resistance detection method in order to decide on a strategy for weed control. Many scientific studies have been carried out to understand herbicide resistance and have been shared with the public. However, more knowledge on herbicide resistance is still needed, especially using genomics, transcriptomics, and other omics techniques, as well as monitoring measures and control strategies of resistant weeds that depend on clear resistance mechanisms.

The aim and scope of this Special Issue, titled “Mechanisms of Herbicide Resistance in Weeds”, are to elucidate the biochemical and molecular resistance mechanisms of weeds to herbicides, especially using omics techniques and novel weed control strategies that have never been reported. Topics of interest include, but are not limited to, the following:

  • Target-site/non-target-site herbicide resistance;
  • Molecular basis of evolution in herbicide resistance;
  • Fitness traits of herbicide-resistant weeds;
  • Omics techniques in weeds;
  • Rapid methods for detection of herbicide resistance in weeds;
  • Management of herbicide/stress resistance.

We welcome novel research articles and reviews addressing all related topics.

The evolved resistance of Bromus japonicus Houtt. to ALS-inhibiting herbicides is well established. Previous studies have primarily focused on target-site resistance; however, non-target-site resistance has not been well characterized. This investigation demonstrated that ALS gene sequencing did not detect any previously known resistance mutations in a mesosulfuron-methyl-resistant (MR) population, and notably, treatment with the P450 monooxygenase (P450) inhibitor malathion markedly heightened susceptibility to mesosulfuron-methyl. Utilizing UPLC-MS/MS analysis confirmed elevated mesosulfuron-methyl metabolism in MR plants. The integration of Isoform Sequencing (Iso-Seq) and RNA Sequencing (RNA-Seq) facilitated the identification of candidate genes associated with non-target sites in a subpopulation with two generations of herbicide selection. Through qRT-PCR analysis, 21 differentially expressed genes were characterized, and among these, 10 genes (comprising three P450s, two glutathione S-transferases, one glycosyltransferase, two ATP-binding cassette transporters, one oxidase, and one hydrolase) exhibited constitutive upregulation in resistant plants. Our findings substantiated that increased herbicide metabolism is a driving force behind mesosulfuron-methyl resistance in this B. japonicus population. Full article
