Summary: Redroot amaranth is a noxious weed affecting soybean production in China. Two populations of this weed showed resistance to bentazone, and the resistance was found to be associated with increased expression of the psbA gene and enhanced herbicide metabolism.

Summary: In this study, two populations of common lambsquarters suspected of being resistant to imazethapyr were investigated. The results showed that both populations exhibited resistance to imazethapyr as well as other herbicides. Genetic analysis revealed specific mutations associated with this resistance, and non-target site resistance mechanisms were found to be involved in one of the populations.

Summary: This study elucidated the molecular basis of resistance to the ALS inhibitor nicosulfuron in crabgrass populations from different provinces in China. The resistance was found to be mainly due to the overexpression of the ALS gene and possible metabolic resistance.

Summary: Swim training has a neuroprotective effect on ALS mice, reducing behavioral disturbances and cognitive dysfunction. It impacts spinal cord metabolism and increases glutathione peroxidase levels, offering protection against oxidative stress. Therapeutic aquatic activity may slow down the progression of ALS.

Summary: In this study, three different accessions of Amaranthus palmeri resistant to 2,4-D were identified and characterized. The resistance/susceptibility ratios of these accessions were determined, and it was found that enhanced metabolism played a role in the evolution of herbicide resistance in some of the accessions. Absorption and translocation of 2,4-D were similar between susceptible and resistant accessions, but the metabolism of 2,4-D was significantly higher in the resistant accessions. Further genetic studies are needed to confirm the presence of target-site resistance mechanisms in these accessions.

Summary: This study analyzed the mechanism of multiple resistance of Echinochloa phyllopogon to three herbicides and found that the resistance was likely due to non-target-site resistance mechanisms. These multiple-resistant populations pose a serious threat to global rice production.

Summary: Two black-grass populations in winter wheat fields in China were found to be resistant to clodinafop-propargyl. The resistance was confirmed through dose-response assays and gene sequence analysis, revealing target-site mutations and enhanced metabolism as the resistance mechanisms.

Summary: A weed called Palmer amaranth in Arkansas, USA has developed resistance to the herbicide S-metolachlor. In this study, researchers investigated the effects of two inhibitors, malathion and NBD-Cl, on the resistant biotype. The resistant biotype showed greater inhibition of root elongation when treated with a combination of NBD-Cl and S-metolachlor compared to treatment with S-metolachlor alone. Metabolites of S-metolachlor were also produced at higher levels in the resistant biotype.

Summary: The study investigated the molecular mechanisms of resistance to the herbicide S-metolachlor in glyphosate-resistant Palmer amaranth populations in Arkansas as early as 2014. The resistance was mainly driven by GSTs, causing metabolic resistance in roots. The analysis of candidate genes revealed similarities with known detoxifying GSTs, suggesting elevated baseline expression and inducibility by S-metolachlor in resistant plants.

Summary: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease caused by multiple genes, but the clear mechanism and effective treatment is still unknown. The contribution of neuronal cytoskeleton in ALS is the least explored among the disrupted processes. This article reviews the properties and studies of 8 genes that directly regulate cytoskeleton function and their contribution to ALS.

Summary: This study revealed that GST-mediated metabolism contributes to trifluralin resistance in the A. palmeri accession from Arkansas, USA. There were no SNPs in the alpha- and beta-tubulin genes between resistant and susceptible accessions, and both accessions displayed similar gene copy numbers.

Summary: Studies indicate that there is a connection between systemic lipid metabolism alterations and neurodegenerative disorders like ALS and FTD, however, research in this area is still lacking. Many patients have mixed forms of ALS and FTD, leading to a variety of disease presentations.

Summary: The study suggests that increased activity of perivascular fibroblast cells and vascular remodeling early in ALS pathogenesis can predict patient survival time. Elevated levels of SPP1 in plasma at disease diagnosis are a stronger predictor of shorter survival in ALS patients than established risk factors.
