CYP81A68 confers metabolic resistance to ALS and ACCase-inhibiting herbicides and its epigenetic regulation in Echinochloa crus-galli

Lang Pan et al.

Summary: Long-term and excessive herbicide use has led to the evolution of herbicide resistance in weeds. This study confirmed the resistance of a global weed population, Echinochloa crus-galli, to ALS-inhibiting herbicide penoxsulam and ACCase-inhibiting herbicides cyhalofop-butyl and metamifop. The resistance was found to be due to the higher expression of a cytochrome P450 gene, CYP81A68, and enhanced metabolism via O-demethylation. Epigenetic regulation, specifically differential methylation of CpG islands, was also observed between resistant and susceptible populations. This research highlights the importance of alternative herbicide selection and nonchemical control tactics in reducing environmental impacts.

CytochromeP450-mediated herbicide metabolism in plants: current understanding and prospects

Nina Gracel Dimaano et al.

Summary: Cytochrome P450s (P450s) play a key role in herbicide metabolism research, providing selectivity in crops and resistance in weeds. While diverse plant P450s with herbicide-metabolizing functions have been identified, fully exploring their potential in crop improvement and herbicide resistance mitigation remains challenging due to the complexity of their function and regulation. Comparing substrate specificity and protein structures of P450s may lead to the development of selective herbicides and crops with higher herbicide tolerance.

Cytochrome P450 CYP81A10v7 in Lolium rigidum confers metabolic resistance to herbicides across at least five modes of action

Heping Han et al.

Summary: The rapid evolution of multiple herbicide resistance in global weed species, especially through metabolic resistance, poses a major threat to herbicide sustainability and global food production. A study found that a P450 gene in Lolium rigidum confers resistance to at least five modes of action across seven herbicide chemistries, indicating a wide cross-resistance profile to many dissimilar herbicides in transgenic plants.

Investigation of clomazone-tolerance mechanism in a long-grain cultivar of rice

Feng Guo et al.

Summary: The long-grain cultivar Kasalath exhibited approximately five-fold higher tolerance to clomazone compared to short-grain cultivars Nipponbare and Koshihikari, suggesting involvement of multiple loci in clomazone tolerance. Chromosome segment substitution lines of Nipponbare/Kasalath and Koshihikari/Kasalath showed partial tolerance to clomazone, indicating a potential genetic basis for developing clomazone-tolerant short-grain cultivars.

A promiscuous fatty acid ω-hydroxylase CYP94A90 is likely to be involved in biosynthesis of a floral nitro compound in loquat (Eriobotrya japonica)

Takuya Yamaguchi et al.

Summary: Nitro groups are commonly found in synthetically manufactured compounds, but loquat emits (2-nitroethyl)benzene as a flower scent. Two cytochrome P450s, CYP79D80 and CYP94A90, are identified to likely catalyze the biosynthesis of (2-nitroethyl)benzene in loquat. CYP94A90 and other CYP94As are promiscuous fatty acid omega-hydroxylases that catalyze the formation of nitro groups from aldoximes in dicot plants.

Heterologous expression of CYP81A6 from rice (Oryza sativa) in Escherichia coli and structural analyses of bensulfuron-methyl metabolites

Takuya Yamaguchi et al.

Summary: Herbicides are often selective, with CYP81A6 in rice playing a key role in tolerance towards acetolactate synthase herbicides such as bensulfuron-methyl. Through heterologous expression in E. coli, it was confirmed that CYP81A6 catalyzes the formation of O-demethylated BSM from BSM, enhancing rice tolerance towards the herbicide.
