During the last years, a great effort has been dedicated at development and employment of diverse approaches for achieving more stress-tolerant climate-flexible crops sustainable yield increases to meet food energy demands future. The ongoing climate change is in fact leading frequent extreme events with negative impact on production, such as increased temperatures, drought, soil salinization well invasive arthropod pests diseases. In this review, "green strategies" (e.g., chemical priming, root-associated microorganisms), advanced technologies genome editing, high-throughput phenotyping) are described basis most recent research evidence. Particularly, attention focused potential use context climate-smart agriculture (the so called "next generation") improve plant tolerance resilience abiotic biotic stresses. addition, gap between results obtained controlled experiments those from application these real field conditions (lab step) also discussed.

We present unresolved questions in plant abiotic stress biology as posed by 15 research groups with expertise spanning eco-physiology to cell and molecular biology. Common themes of these include the need better understand how plants detect water availability, temperature, salinity, rising carbon dioxide (CO2) levels; environmental signals interface endogenous signaling development (e.g. circadian clock flowering time); this integrated controls downstream responses stomatal regulation, proline metabolism, growth versus defense balance). The plasma membrane comes up frequently a site key transport events mechanosensing lipid-derived signaling, aquaporins). Adaptation extremes CO2 affects hydraulic architecture transpiration, well root shoot morphology, ways not fully understood. Environmental adaptation involves tradeoffs that limit ecological distribution crop resilience face changing increasingly unpredictable environments.

Plant metabolites and signaling pathways in response to biotic and abiotic stresses: Exploring bio stimulant applications

Plant Stress, Год журнала: 2024, Номер 12, С. 100454 - 100454

Опубликована: Март 29, 2024

Plants are constantly exposed to a wide array of complex interactions involving various environmental factors, leading disruptions in their metabolic processes and incurring physiological costs when faced with biotic abiotic stress. In response these stimuli, plants have developed diverse signaling mechanisms adapt the prevailing conditions. equipped different pathways undergo changes at transcriptomic level survive stress stimuli. The divided into four major subsections: signal perception, transduction, regulation gene expression responses. Transcription factors (TFs) play crucial role organization defense by regulating downstream expression. Primary metabolites (PMs) Secondary (SMs) represent fundamental compounds involved plant mechanisms. These extracts promising method increasing tolerance stresses can be used as biostimulants. This review aimed elucidate contributions PMs SMs reactions, well biosynthesis pathways. Additionally, interplay between was discussed. molecular physiology responses stimuli via pathway described this research.
