AI Article Synopsis

  • * Recent studies highlight the role of nucleotide-binding domain/leucine-rich-repeat (NLR) receptors in plant immunity, particularly how they interact with calcium signaling to activate defenses against pathogens.
  • * New discoveries involving TIR domain NLRs show that specific nucleotide signals can modulate immune responses, opening up innovative strategies for enhancing disease resistance in crops.

Article Abstract

While working for the United States Department of Agriculture on the North Dakota Agricultural College campus in Fargo, North Dakota, in the 1940s and 1950s, Harold H. Flor formulated the genetic principles for coevolving plant host-pathogen interactions that govern disease resistance or susceptibility. His 'gene-for-gene' legacy runs deep in modern plant pathology and continues to inform molecular models of plant immune recognition and signaling. In this review, we discuss recent biochemical insights to plant immunity conferred by nucleotide-binding domain/leucine-rich-repeat (NLR) receptors, which are major gene-for-gene resistance determinants in nature and cultivated crops. Structural and biochemical analyses of pathogen-activated NLR oligomers (resistosomes) reveal how different NLR subtypes converge in various ways on calcium (Ca) signaling to promote pathogen immunity and host cell death. Especially striking is the identification of nucleotide-based signals generated enzymatically by plant toll-interleukin 1 receptor (TIR) domain NLRs. These small molecules are part of an emerging family of TIR-produced cyclic and noncyclic nucleotide signals that steer immune and cell-death responses in bacteria, mammals, and plants. A combined genetic, molecular, and biochemical understanding of plant NLR activation and signaling provides exciting new opportunities for combatting diseases in crops.

Unlabelled: Purpose: Chemotherapy-induced peripheral neuropathy (CIPN) with associated weakness, areflexia, neuropathic pain, and sensory loss, is a common occurrence in children treated for cancer. However, accurate, quantifiable descriptions of gait deviations due to CIPN are lacking. This scoping review explores common gait abnormalities in children with CIPN.

Primary care researchers are increasingly at the forefront of developing innovations and new research methods to address complex issues in health care, including multi-morbidity, social determinants of health, health equity, managing population health in clinical practice, patient satisfaction, and provider burnout. Research demonstrates that "primary care is the only health care component where an increased supply is associated with better population health and more equitable outcomes." As a primary care specialty, family medicine has evolved beyond its initial focus on clinical practice and education to realizing the imperative for the discipline to robustly engage in research and embrace the responsibility to generate the evidence that drives changes in primary care practice and policy.

Early life environmental exposures, even those experienced before conception, can shape health and disease trajectories across the lifespan. Optimizing the detection of the constellation of exposure effects on a broad range of child health outcomes across development requires considerable sample size, transdisciplinary expertise, and developmentally sensitive and dimensional measurement. To address this, the National Institutes of Health (NIH) Environmental influences on Child Health Outcomes (ECHO) Cohort Study is an observational longitudinal pediatric cohort study.
