AI Article Synopsis
- The white spruce has been found to have a chemical defense mechanism against spruce budworms, primarily involving compounds called hydroxyacetophenones.
- The study reviews how these compounds exist in different forms (aglycons and glucosides) and highlights the genetic, molecular, and biochemical aspects of this defense.
- New findings reveal variations in defense responses during development and the timing of herbivore attacks, with implications for both evolution and breeding strategies.
Article Abstract
We review a recently discovered white spruce () chemical defense against spruce budworm ( involving hydroxyacetophenones. These defense metabolites detected in the foliage accumulate variably as the aglycons, piceol and pungenol, or the corresponding glucosides, picein and pungenin. We summarize current knowledge of the genetic, genomic, molecular, and biochemical underpinnings of this defense and its effects on . We present an update with new results on the ontogenic variation and the phenological window of this defense, including analysis of transcript responses in to herbivory. We also discuss this chemical defense from an evolutionary and a breeding context.

Forests face an escalating threat from the increasing frequency of extreme drought events driven by climate change. To address this challenge, it is crucial to understand how widely distributed species of economic or ecological importance may respond to drought stress. In this study, we examined the transcriptome of white spruce (Picea glauca (Moench) Voss) to identify key genes and metabolic pathways involved in the species' response to water stress.

Importance: For hospitalized critically ill adults with suspected sepsis, procalcitonin (PCT) and C-reactive protein (CRP) monitoring protocols can guide the duration of antibiotic therapy, but the evidence of the effect and safety of these protocols remains uncertain.
Objective: To determine whether decisions based on assessment of CRP or PCT safely results in a reduction in the duration of antibiotic therapy.
Design, Setting, And Participants: A multicenter, intervention-concealed randomized clinical trial, involving 2760 adults (≥18 years), in 41 UK National Health Service (NHS) intensive care units, requiring critical care within 24 hours of initiating intravenous antibiotics for suspected sepsis and likely to continue antibiotics for at least 72 hours.

Article Synopsis
- The study highlights a growing concern for the mental health of sign language interpreters, alongside traditional physical health issues, prompting a need for a broader, more integrated approach to their occupational health.
- Focus groups with 27 interpreters revealed major concerns like workplace violence, vicarious trauma, poor work-life balance, and negative organizational culture, which contribute to their overall well-being.
- Proposed solutions include prioritizing work tasks, establishing supportive communities, and encouraging physical exercise to improve the safety and mental health of interpreters in their profession.

Climate conditions throughout the 21st century across much of western Canada's boreal forest have been drier than normal leading to significant impacts on forest productivity and tree growth. Determining the limiting factors of radial growth in common boreal tree species under current and future conditions is crucial to reconcile how they will continue to respond to climate change. In this study, we used a network of 26 white spruce tree-ring chronologies south of its natural range as an artificially constructed trailing edge to assess climate-growth relationships and limiting factors by identifying seasonal climate relationships and using the Vaganov-Shashkin Lite (VS-Lite) model, respectively.

DNA methylation plays a crucial role in the development of somatic embryos (SEs) through the regulation of gene expression. To examine the impact of DNA methylation on gene expression during early SE development in , the demethylation reagent 5-aza-dC (5-aza-2'-deoxycytidine) was employed to modify DNA methylation regions and levels during the pre-maturation stage of somatic embryogenesis. The application of 2.
