Summary: Monochoria vaginalis is an aquatic herbaceous plant that is often found as a noxious weed in paddy fields. This research evaluated the resistance levels of M. vaginalis to different groups of herbicides and investigated the mutations in the ALS gene of the resistant biotype. The study found that the resistant biotype had varying levels of resistance to different herbicides and had specific amino acid substitutions in the ALS protein. Further research is needed to understand the molecular basis of resistance mechanisms and to develop control strategies.

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: This study identified 12 common herbicide-target genes and their proteins from seven species of Weeds of National Significance in Australia using high-throughput genome sequencing. The study found high sequence conservation at the herbicide-target sites among the diverse weed species. Mutations observed in the proteins of fireweed and parthenium suggest resistance of these weeds to certain herbicides. These findings provide important insights for herbicide discovery and development.

Summary: Opsins are universal photoreceptive proteins in animals that play a role in regulating cyclic nucleotide signaling. Different types of opsins in different animals form different active states during photoconversion, and the position of the negatively charged counterion varies. Through analyzing a distinct group of opsins, researchers found that the counterion position change is related to the efficiency of signaling. This study provides insights into the evolutionary process of opsins and their signaling efficiency.

Summary: In organic paddy fields, the application of fresh rice bran suppresses the germination of Monochoria vaginalis, a tough weed to control. However, the scarcely decomposable component of rice bran stimulates the germination. The presence of conflicting factors that suppress and enhance germination might destabilize the efficacy of rice bran.

Summary: Convergence is the phenomenon where similar phenotypes evolve independently in different lineages. Resistance to toxins in animals is an example of convergence, where molecular adaptations have evolved to counteract the harmful effects of toxins. However, resistance adaptations may carry fitness costs if they disrupt the normal physiology of the resistant animal.

Summary: Armadillo palmeri populations in Spain and Italy have shown resistance to acetolactate synthase (ALS) inhibitors. Mutant ALS alleles, especially 574-Leu, were found to be the main cause of resistance among these populations. Haplotype analyses revealed different evolutionary histories and independent introduction events in both countries.

Summary: This article discusses the phenomenon of hybridization in agricultural weeds and its management implications. It suggests that hybridization can promote weed evolution and exacerbate weed-crop competition, but does not always increase weediness. The article also highlights research priorities in hybridization and emphasizes the importance of weed management.

Summary: Resistance to iodosulfuron, an herbicide targeting acetolactate synthase (ALS), was identified in a population of Lolium perenne L. from Canterbury, New Zealand. The resistance was due to enhanced herbicide metabolism and a target-site gene mutation. This study provides insights into the resistance mechanisms of ALS-inhibiting herbicides in Lolium perenne and highlights the importance of integrated weed management approaches.

Summary: The chloroplast, evolved from endosymbiosis, has a highly conserved genome organization and a slow rate of molecular evolution. Through analysis of angiosperm plastid genomes, it was found that the distance from the replication origin, amino acid composition, and mRNA abundance are key factors influencing the rate of molecular evolution in plastid genes. These factors account for over 50% of the variation in evolution rate and have constrained the adaptive evolution and evolvability of the chloroplast.

Summary: This paper proposes a DRL-assisted co-evolutionary differential evolution algorithm (CEDE-DRL) that effectively utilizes DRL to help EAs solve constrained optimization problems. The method incorporates co-evolution into the extraction of training data, improves the accuracy of the neural network model through information exchange between multiple populations, and uses multiple constraint handling techniques for offspring selection. DRL is used to evaluate the population state, taking into account feasibility, convergence, and diversity. Additionally, an adaptive operator selection and individual archive elimination mechanism is added to avoid premature convergence and local optima.

Summary: The evolution of herbicide resistance in different weed species is a remarkable example of adaptation to human-driven disturbance. In Oregon, multiple populations of Lolium multiflorum have developed resistance to glyphosate. Through phenotypic and genetic analyses, it was found that the resistance is likely due to independent evolution in different populations, and not through gene flow. Potential genetic loci associated with the resistance phenotype were also identified.

Summary: In constrained optimization evolutionary algorithms (COEAs), achieving a balance between the objective function and constraints is crucial. This study proposes a Hybrid Constraint-handling Technique (HCT) that utilizes the information of the population's evolution process to maintain this balance. The proposed ECO-HCT algorithm combines evolutionary algorithms with HCT to solve complex constraint optimization problems (COPs) and has shown competitive performance compared to other advanced methods.

Summary: This study reports how a new phenotype of hybrids between two Imperata cylindrica ecotypes contributes to rapid reproductive isolation from their parents and affects hybrid fitness. The hybrid populations consist of only F-1 individuals, without advanced generation hybrids. The flowering phenology of the F-1 plants is delayed, preventing backcrossing, and changing seed dispersal time. This study highlights the importance of hybrid traits in driving rapid reproductive isolation.

Summary: This study compared the herbicide specificity of CYP81A cytochrome P450s between rice and a weed called Echinochloa phyllopogon. The results showed differences in metabolite formation and activity towards herbicides between rice CYP81A6 and Echinochloa phyllopogon CYP81A12 and CYP81A21. These differences can be utilized to design inhibitors for weed CYP81As and develop selective herbicide ingredients metabolized by crop CYP81As.
