AI Article Synopsis

  • - Aldehydes, which are lipid derivatives found in higher plants, play critical roles in various physiological and biological processes and are produced through both enzymatic and non-enzymatic pathways.
  • - While they can damage proteins and nucleic acids at high concentrations, making them harmful to plant growth, aldehyde levels can also serve as biomarkers for plant health.
  • - Recent studies highlight that certain aldehydes, at specific concentrations, may activate survival and defense mechanisms in plants, suggesting a complex role that includes detoxification strategies and signaling effects.

Article Abstract

Aldehydes, derivatives of lipids, are ubiquitously produced through non-enzymatic and enzymatic pathways in higher plants and participate in many physiological and biological processes. Increasing evidence demonstrates that aldehydes are involved in plants response to many abiotic stresses, such as light, drought, heat and nutrient deficiency. In plant cells, endogenously triggered or exogenously applied high concentrations of aldehydes can damage proteins and nucleic acid, disturb redox homeostasis, and consequently inhibit plant growth; therefore, they are considered cytotoxins. Aldehyde levels are also used as biomarkers to evaluate the health status of plants. Further genetic research shows that several enzymes have strong capacities to detoxify these electrophilic aldehydes. Small molecules, such as carnosine and glutathione, also exhibit the ability to scavenge aldehydes, effectively promoting plant growth. Recently, increasing evidence has shown that certain aldehydes at certain concentrations can upregulate survival genes, activate antioxidant responses, increase defense against pathogens and stimulate plant growth. This review summarizes recent studies of lipid-derived aldehydes in higher plants, mainly focusing on the generation pathway, toxic effects, and detoxification strategies. In addition, the signaling effects of aldehydes in plants are also discussed.
