Summary
Plant priming with phytohormones enhances crop adaptation to climate change stresses like drought and heat. This method improves biomass yield and quality through molecular and epigenetic modifications.
Area of Science:
- Agricultural Science
- Plant Physiology
- Molecular Biology
Background:
- Climate change poses significant threats to global agriculture, necessitating strategies for crop adaptation.
- Plant priming is a promising approach to enhance stress tolerance and improve crop productivity.
- Phytohormones play a crucial role in mediating plant responses to environmental stimuli.
Purpose of the Study:
- To review the role of phytohormones in inducing plant priming for improved crop adaptation.
- To explore the physiological, morphological, and molecular effects of phytohormone-induced priming.
- To highlight the epigenetic changes associated with phytohormone priming.
Main Methods:
- Literature review focusing on phytohormone-induced priming in crop plants.
- Analysis of key phytohormones: abscisic acid, salicylic acid, jasmonic acid, and gibberellins.
- Examination of molecular and epigenetic mechanisms underlying priming.
Main Results:
- Phytohormone priming effectively enhances plant tolerance to abiotic stresses (water deficiency, low temperatures, heat, soil pollution).
- Priming improves both the quantity and quality of crop biomass.
- Phytohormones induce significant molecular and epigenetic changes, leading to long-term adaptation.
Conclusions:
- Phytohormone-induced priming is a viable strategy for developing climate-resilient crops.
- Understanding the molecular and epigenetic basis of priming can optimize agricultural practices.
- Further research into phytohormone signaling pathways will advance crop adaptation strategies.

01:56Plant Hormones
23.4K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

02:45Biological Clocks and Seasonal Responses
34.6K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

01:25Cell Signaling in Plants
5.6K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

18.6K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
