Summary: Chickpea is an important crop in Israel, but sensitive to imidazolinone herbicides. A chickpea line resistant to these herbicides was developed using chemical mutagenesis, with a point mutation detected in one of the genes encoding the AHAS catalytic subunit. The mutation provided resistance to a specific group of herbicides and showed single-gene semi-dominant inheritance pattern, as confirmed by genetic transformation in tobacco plants.

Summary: Significant heterosis has been documented in Brassica juncea L., where male sterility induced by the herbicide tribenuron-methyl (TBM) has been shown to effectively increase pollen sterility and inhibit seed yield, making it a practical chemical hybridization agent in B. juncea breeding programs.

Summary: Assessing the capacity of weeds to develop herbicide resistance before it occurs in the field is crucial for effective chemical weed control. This study used herbicide selection and controlled crosses to accelerate the evolution of resistance to two commonly used herbicides in Ambrosia artemisiifolia. The results showed that non-target-site-based resistance (NTSR) to herbicides was significantly increased in just two generations of selection. NTSR to the tested herbicides emerged and was reinforced in subsequent generations. Further bioassays confirmed the emergence of resistance to imazamox and/or tribenuron in multiple A. artemisiifolia populations. NTSR was found to be the predominant type of resistance, with only one population showing a mutant ALS allele in addition to NTSR. This study highlights the importance of pre-emptive assessment of resistance evolution in weed populations.

Summary: A new mutation conferring tolerance to IMI in cotton was isolated in this research, showing promising potential for the development of commercial cotton cultivars with IMI tolerance. The mode of inheritance of this trait was determined, and field assays confirmed the increased tolerance of the mutant line compared to non-tolerant genotypes.

Summary: Based on the pharmacophore binding strategy and the principle of bioelectronic isobaric, a series of novel thiourea compounds containing aromatic-substituted pyrimidines were designed and synthesized using the sulfonylurea bridge as the parent structure. Some compounds showed good herbicidal activity, especially compounds 4d and 4f, which exhibited higher comparative activity than the commercial herbicide bensulfuron-methyl. The preliminary structure-activity relationship (SAR) and in vivo AHAS enzyme activity inhibition experiments further confirmed the activity of these compounds.

Summary: The application of herbicides is an effective strategy for weed control, and the development of herbicide-resistant crops can enhance weed management. However, the use of the herbicide tribenuron-methyl (TBM) is limited in rapeseed fields due to rapeseed's sensitivity to TBM. A study was conducted on the TBM-resistant rapeseed mutant M342 and its wild-type plants, revealing that M342 exhibited improved tolerance to TBM and had higher levels of proteins related to non-target-site resistance (NTSR) to herbicides compared to the wild-type plants. Differentially accumulated proteins (DAPs) between the two genotypes were enriched in glutathione metabolism and oxidoreduction coenzyme metabolic process, providing protection against oxidative stress caused by TBM. These findings offer insights into the mechanism of NTSR in plants and contribute to the development of herbicide-resistant crops.

Summary: This study investigates the prevalence, mode of evolution, and spread of resistance-endowing ALS alleles in corn poppy populations in France. With the use of massively parallel amplicon sequencing, it was found that mutant ALS alleles have complex geographic distributions, which could be attributed to large population sizes, multiple independent mutation events, and human-mediated spread of resistance. The study also reveals that mutant ALS alleles are associated with resistance to the synthetic auxin 2,4-D.

Summary: A study in southern Spain found that Sinapis alba populations have developed resistance to the acetolactate synthase-inhibiting herbicide tribenuron-methyl. The resistant populations showed significantly higher resistance to tribenuron-methyl compared to the susceptible population. A mutation in the ALS gene and P450-mediated metabolism were identified as contributing factors to the resistance. Alternative chemical control methods were effective in controlling both the resistant and susceptible populations.

Summary: Flixweed in the North China Plain has developed resistance to the herbicide florasulam, with 30 populations showing resistance, 9 at high risk of resistance, and 6 being susceptible. Some populations with specific genetic mutations showed cross-resistance to all ALS inhibitors while remaining sensitive to other herbicides.

Summary: Centaurea cyanus, a weed species commonly found in fields with cereals, sugar beet, and maize, shows resistance mainly against acetolactate synthase (ALS) inhibitors. Genetic variability in ALS sequence has been observed among resistant plants, with four amino acid sequence changes identified in some resistant plants compared to susceptible ones. Further research is needed to confirm the significance of these mutations in herbicide resistance development.

Summary: A population of Echinochloa crus-galli obtained from direct-seeding rice fields in Jiangxi Province, China, exhibited high resistance levels to the herbicide cyhalofop-butyl and evolved cross-resistance to multiple herbicides. Analysis of ACCase gene sequencing and metabolic inhibition experiments suggested that the resistance may be due to enhanced metabolic activity.

Summary: Digitaria ciliaris var. chrysoblephara is a xerophytic weed that severely invades rice fields in China due to the use of rice mechanical direct seeding technology. This study identified a resistant population (M5) with a mutation in ACCase1 gene, resulting in broad-spectrum resistance to three classes of ACCase-inhibiting herbicides. The other two populations (M2 and M4) only exhibited resistance to aryloxyphenoxypropionate herbicides. In addition, pre-treatment with the P450 inhibitor PBO significantly reduced the resistance to aryloxyphenoxypropionate herbicide in the M2 population. Soil-applied herbicides such as pretilachlor, pendimethalin, and oxadiazon effectively inhibit the germination and growth of D.ciliaris var. chrysoblephara.
