- Plant Defense Mechanisms Against Biotic Stress | SpringerLink
Plant reactive mechanisms, ranging from molecular signaling pathways involving salicylic acid and jasmonic acid to a physical level of trichome emergence or wax sheaths, show an impressive array of tactics to protect against pathogens and herbivores
- Biotic Stress - an overview | ScienceDirect Topics
These secondary metabolites trigger different plant defense mechanisms in the form of ascorbic acid, antioxidative enzymes (peroxidase, polyphenol oxidase, lipoxygenases), salicylic acid, jasmonic acid, and Ca2+ against biotic stress and also act as toxins (terpenes, alkaloids, and phenolic compounds) against plant pathogens
- Biotic stress - Wikipedia
Biotic stress is stress that occurs as a result of damage done to an organism by other living organisms, such as bacteria, viruses, fungi, parasites, beneficial and harmful insects, weeds, and cultivated or native plants [1] It is different from abiotic stress, which is the negative impact of non-living factors on the organisms such as temperature, sunlight, wind, salinity, flooding and
- Biotic and Abiotic Stresses in Plants - IntechOpen
The abiotic stress causes the loss of major crop plants worldwide and includes radiation, salinity, floods, drought, extremes in temperature, heavy metals, etc On the other hand, attacks by various pathogens such as fungi, bacteria, oomycetes, nematodes and herbivores are included in biotic stresses
- Biotic and Abiotic Stresses in Plants: Challenges, Responses, and . . .
The interplay between biotic and abiotic stresses presents significant challenges to plant growth and productivity, with complex molecular and physiological mechanisms underlying these interactions Recent research emphasizes the critical role of cross-talk between plant immune systems, signaling pathways, and stress-responsive genes in managing these dual stresses Strategies for enhancing

10 1 INTRODUCTION Biotic stress refers to the adverse effects on plants caused by living organisms, including pathogens (bacteria, viruses, fungi), insects, nematodes, weeds, and other plants These stresses can lead to various negative outcomes such as diseases, reduced growth, lower yields, and in severe cases, plant death Biotic stress contrasts with abiotic stress, which is caused by non
- Biotic Stress | Plant Physiology | Oxford Academic
Plants use specific receptor proteins on the cell surface to detect host-derived danger signals released in response to attacks by pathogens or herbivores and activate immune responses against them
- Plant Responses to Biotic and Abiotic Stresses: From Cellular to . . .
Plants continually encounter biotic and abiotic stresses, which threaten their growth, development, and productivity Biotic stresses emanate from interactions with other living organisms, such as pathogens, pests, and weeds, whereas abiotic stresses result from environmental factors, such as drought, salinity, extreme temperatures, and heavy
