Summary
Plants defend against herbivores by producing toxins and attracting predators. This review details plant perception of herbivory and the signalling pathways mediating these complex defence responses.
Area of Science:
- Plant biology
- Ecology
- Biochemistry
Background:
- Plants have co-evolved with herbivores for millions of years, developing sophisticated defense mechanisms.
- Herbivore attack triggers metabolic reconfigurations in plants, producing defensive compounds and volatile signals.
Purpose of the Study:
- To review recent advancements in understanding plant recognition of herbivory.
- To elucidate the signalling pathways involved in plant defense against herbivores.
- To explore signals that mediate local and systemic plant responses to herbivore attack.
Main Methods:
- Review of scientific literature on plant-herbivore interactions and signaling.
- Analysis of molecular and physiological responses to herbivore elicitors.
- Summary of research on plant perception, defense compound production, and signal transduction.
Main Results:
- Plants perceive herbivory through specific compounds in herbivore oral secretions and oviposition fluids.
- Herbivory triggers rapid cellular events including membrane depolarization, calcium influx, and mitogen-activated protein kinase (MAPK) activation.
- Plant defense responses are systemic, occurring in both attacked and unattacked tissues.
Conclusions:
- Plant defense against herbivores is a complex, regulated process involving intricate signaling networks.
- Understanding these plant defense mechanisms is crucial for agriculture and ecology.
- Further research into plant signaling pathways can reveal novel strategies for crop protection.

Cell Signaling in Plants
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...
Defenses Against Pathogens and Herbivores
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.
Photoreceptors and Plant Responses to Light
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.
Short-distance Transport of Resources
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.
Plant Hormones
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.
