Damage activates EXG1 and RLP44 to suppress vascular differentiation during regeneration in Arabidopsis.

Plants possess remarkable regenerative abilities to form de novo vasculature after damage and in response to pathogens that invade and withdraw nutrients. To look for common factors that affect vascular formation upon stress, we searched for Arabidopsis thaliana genes differentially expressed upon Agrobacterium infection, nematode infection and plant grafting. One such gene was cell wall related and highly induced by all three stresses and was named ENHANCED XYLEM AND GRAFTING1 (EXG1) since mutations in it promoted ectopic xylem formation in Vascular cell Induction culture System Using Arabidopsis Leaves (VISUAL) and enhanced graft formation.

Sex-specific cognitive benefits and anti-inflammatory effects of coumestrol pretreatment in transient global cerebral ischemia.

Cerebral Global Ischemia (CGI) is a devastating neurological condition affecting millions globally each year, leading to significant inflammatory responses and long-term consequences, including delayed neuronal death and neurocognitive impairment. Following brain injury, resident microglial cells are activated, triggering pro-inflammatory cytokine expression and altering neuroimmune processes in a sex-dependent manner, particularly within the hippocampus. Coumestrol, a plant estrogen, is promoted as an alternative to post-menopausal hormone therapy due to its various mechanisms that enhance brain health, including its anti-inflammatory effects.

Preparation of a Self-Assembled Nanoantiviral Pesticide with Strong Adhesion Performance for Efficiency Control of Destructive .

In this context, we reported for the first time the design and development of a self-assembled nanoantiviral pesticide based on the star polycation (SPc) and the broad-spectrum fungicide/antiviral agent seboctylamine for field control of (SMV), a highly destructive plant virus in soybean crops. The SPc could self-assemble with seboctylamine through hydrogen bonds and van der Waals forces, and the complexation with SPc reduced the particle size of seboctylamine to form a spherical seboctylamine/SPc complex. In addition, the contact angle of seboctylamine decreased, and its retention increased with the aid of SPc, indicating excellent wetting properties and strong leaf surface adhesion performance.

Comparing field and lab quantitative stable isotope probing for nitrogen assimilation in soil microbes.

Unlabelled: Soil microbial communities play crucial roles in nutrient cycling and can help retain nitrogen in agricultural soils. Quantitative stable isotope probing (qSIP) is a useful method for investigating taxon-specific microbial growth and utilization of specific nutrients, such as nitrogen (N). Typically, qSIP is performed in a highly controlled lab setting, so the field relevance of lab qSIP studies remains unknown.

Identification and functional characterization of a fructose-inducible phosphotransferase system in Sp7.

Plant growth-promoting rhizobacterium Sp7 utilizes fructose efficiently via a fructose phosphotransferase system (Fru-PTS). Its genome encodes two putative Fru-PTS, each consisting of FruB (EIIA), FruK (Pfk), and FruA (EIIBC) proteins. We compared the proteomes of Sp7 grown with malate or fructose as sole carbon source, and noticed upregulation of the constituent proteins of Fru-PTS1 only on fructose.

Ecological Drivers of Evolution of Swine Influenza in the United States: A Review.

Influenza A viruses (IAVs) pose a major public health threat due to their wide host range and pandemic potential. Pigs have been proposed as "mixing vessels" for avian, swine, and human IAVs, significantly contributing to influenza ecology. In the United States, IAVs are enzootic in commercial swine farming operations, with numerous genetic and antigenic IAV variants having emerged in the past two decades.

Exploring the Interface Between Planetary Boundaries and Palaeoecology.

The concepts of planetary boundaries are influential in the sustainability literature and assist in delineating the 'safe operating spaces' beyond which critical Earth system processes could collapse. Moving away from our current trajectory towards 'hothouse Earth' will require knowledge of how Earth systems have varied throughout the Holocene, and whether and how far we have deviated from past ranges of variability. Such information can inform decisions about where change could be resisted, accepted or where adaptation is inevitable.
