Protein phosphatases (PPs) are a class of enzymes that play a critical role in cellular regulation by catalyzing the removal of phosphate groups from proteins. This dephosphorylation process is essential for controlling and modulating various cellular functions, including signal transduction, cell cycle progression, metabolic regulation, and stress responses. This study focuses on the comprehensive genomic identification, evolutionary analysis, and transcript profiling of the PP2C gene family within Solanum lycopersicum, an economically significant crop with substantial agricultural and nutritional importance.

The Role of Electron Transfer in Copper-Mediated C(sp)-H Trifluoromethylation.

Angew Chem Int Ed Engl

December 2024

Department of Chemistry and Biochemistry, The Ohio State University, 100 West 18th Avenue, Columbus, OH, 43210, United States.

We report copper(II) and copper(III) trifluoromethyl complexes supported by a pyridinedicarboxamide ligand (L) as a platform for investigating the role of electron transfer in C(sp)-H trifluoromethylation. While the copper(II) trifluoromethyl complex is unreactive towards (hetero)arenes, the formal copper(III) trifluoromethyl complex performs C(sp)-H trifluoromethylation of a wide range of (hetero)arenes. Mechanistic studies using the copper(III) trifluoromethyl complex suggest that the mechanism of arene trifluoromethylation is substrate-dependent.

December 2024

USDA ARS, Aflatoxin Control Laboratory, 416 West Congress Street, Tucson, Arizona, United States, 85701;

Fusarium ear rot (FER) and Gibberella ear rot (GER) caused by Fusarium species are major diseases affecting maize production in Ethiopia. In addition to reducing quality and yield, these fungi can produce mycotoxins that contaminate maize kernels and, thereby, pose health hazards to humans and livestock. A survey was conducted in 10 administrative zones of Ethiopia within the major maize-growing regions of the country to identify the species of Fusarium associated with ear rot.

Department of Pharmaceutical Sciences, Mohanlal Sukhadia University, Udaipur, Rajasthan, India.

Traditional drug discovery approach is based on one drug-one target, that is associated with very lengthy timelines, high costs and very low success rates. Network pharmacology (NP) is a novel method of drug designing, that is based on a multiple-target approach. NP integrates systems such as biology, pharmacology and computational techniques to address the limitations of traditional methods of drug discovery.

The muscle-specific microRNA miR-206 has recently emerged as a potential regulator of genes involved in the formation and regeneration of the neuromuscular junction (NMJ). This study investigated miR-206-3p (miR-206) expression in synaptic and non-synaptic regions of denervated mice and α-dystrobrevin (Dtna)-knockout mice, as well as its impact on the formation and/or maintenance of agrin-induced acetylcholine receptor (AChR) clusters. In denervated, Dtna-deficient and crushed muscles, miR-206 expression significantly increased compared to what was seen for innervated muscles.

Premise: The soils in lowland tropics are teeming with microbial life, which can impact plant community structure and diversity through plant-soil feedbacks. While bacteria and fungi have been the focus of most studies in the tropics, oomycetes may have an outsized effect on seed and seedling health and survival, given their affinity for moister, warmer environments.

Methods: We assessed the diversity and pathogenicity of oomycete species present in a lowland tropical forest in Panama.

Objective: This study examined relationships between home smoking/vaping bans and caregiver restrictions on child access to tobacco in the home among rural, Black/African American caregivers who smoke.

Methods: Data were from the baseline survey of a randomized trial conducted in 2020-2022 among caregivers who smoke cigarettes and/or little cigars/cigarillos (N = 188). Logistic regressions examined associations between independent variables (tobacco product-specific and comprehensive home smoking/vaping bans) and dependent variables (caregiver keeps tobacco in the home; among caregivers with tobacco at home, caregiver restricts child tobacco access at home) Models were adjusted for caregiver tobacco use, income, and additional covariates based on stepwise selection.

Developing a separation system to enable real-time recovery of acetone-butanol during fermentation.

Appl Microbiol Biotechnol

November 2024

Department of Animal Science, College of Food Agricultural and Environmental Sciences, The Ohio State University, Wooster, OH, 44691, USA.

Article Synopsis
  • The study developed hydrophobic stainless steel meshes for effective recovery of ABE (acetone, butanol, and ethanol) from bioreactors during vacuum-assisted gas stripping, minimizing water loss.
  • Three types of meshes with varying pore sizes (180 µm, 300 µm, and 425 µm) were coated with zinc oxide and polydimethylsiloxane, showing that the 180-µm mesh retained significantly more water (54-65% more) compared to uncoated ones.
  • The technology increased butanol concentration in recoveries by up to 10.8-fold and proved effective for real-time ABE extraction from lignocellulosic fermentation without clogging issues.

Behavioral syndromes in paper wasps: Links between social and non-social personality in .

Curr Zool

October 2024

Department of Ecology and Evolutionary Biology, University of Michigan, 1105 N University Ave, Ann Arbor, MI 48109, USA.

Although much work has focused on non-social personality traits such as activity, exploration, and neophobia, there is a growing appreciation that social personality traits play an important role in group dynamics, disease transmission, and fitness and that social personality traits may be linked to non-social personality traits. These relationships are important because behavioral syndromes, defined here as correlated behavioral phenotypes, can constrain evolutionary responses. However, the strength and direction of relationships between social and non-social personality traits remain unclear.

Fungal Biol

November 2024

USDA, Agricultural Research Service, National Center for Agricultural Utilization Research, Mycotoxin Prevention and Applied Microbiology Unit, 1815 N. University St., Peoria, IL, 61604, USA.

Article Synopsis
  • Fusarium verticillioides is a fungus that can act as both an endophyte and a pathogen in maize, producing harmful mycotoxins like fumonisins, which are linked to various diseases, including cancer in some animals.
  • The research investigates how F. verticillioides interacts with other co-infecting fungi and how their metabolites, particularly low molecular weight acids, may influence its mycotoxin production.
  • Findings show that exposure to fusaric acid significantly upregulates over 225 genes in F. verticillioides, suggesting it may serve as a signaling molecule, while other acids only slightly affect gene expression, indicating a complex communication role among the fungi.

Department of Natural Sciences, College of Arts, Sciences, and Letters, University of Michigan-Dearborn, 4901 Evergreen Rd, Dearborn, MI 48128, USA. Electronic address:

Loss-of-function mutations in the tissue-nonspecific alkaline phosphatase (TNAP) gene can result in hypophosphatasia (HPP), an inherited multi-systemic metabolic disorder that is well-known for skeletal and dental hypomineralization. However, emerging evidence shows that both adult and pediatric patients with HPP suffer from cognitive deficits, higher measures of depression and anxiety, and impaired sensorimotor skills. The cerebellum plays an important role in sensorimotor coordination, cognition, and emotion.

L-Cysteine-Catalysed Hydration of Activated Alkynes.

Angew Chem Int Ed Engl

January 2025

IUQOEM - Department of Organic and Inorganic Chemistry, School of Chemistry, University of Oviedo, Julián Clavería 8, 33006, Oviedo, Spain.

Hydration reactions consist of the introduction of a molecule of water into a chemical compound and are particularly useful to transform alkynes into carbonyls, which are strategic intermediates in the synthesis of a plethora of compounds. Herein we demonstrate that L-cysteine can catalyse the hydration of activated alkynes in a very effective and fully regioselective manner to access important building blocks in synthetic chemistry such as β-ketosulfones, amides and esters, in aqueous media. The mild reaction conditions facilitated the integration with enzyme catalysis to access chiral β-hydroxy sulfones from the corresponding alkynes in a one-pot cascade process in good yields and excellent enantiomeric ratios.
