Damage-associated molecular patterns (DAMPs) as future plant vaccines that protect crops from pests

摘要: Abstract Domestication reduced the resistance of most crops which, therefore, require an ever-increasing application pesticides. Nevertheless, in domesticated species, against herbivores and disease agents can be activated by so-called elicitors. Here, we review various strategies biological pest control particularly focus on damage-associated molecular patterns (DAMPs) as a potential novel class plant vaccines: plant-derived molecules that trigger immunity because they indicate damage when appear extracellular space or, case damage-induced volatile compounds, aerial around plant. The or algal extracts, which arguably contain many DAMPs, enhanced herbivory cabbage, tomato maize to fungal bacterial all major grain banana, apple, grapevine, melon, tomato, cucumber carrot. Similarly, purified DAMPs such ATP, fragmented DNA, peptides, cell-wall fragments, volatiles, elicited resistance-related responses species wheat, corn, soybean, bean, eggplant, cucumber, potato tomato. In conclusion, plant-based preparations with different degrees purity improve health multiple horticultural plants. Commercial products based extracts are available, leaf even home-made, e.g., low-income farmers. We conclude their derivatives bear as-yet underestimated serve environmentally friendly vaccines cultivated
