Plant defense mechanisms can be passed down through generations, influencing ecological and evolutionary interactions. This transgenerational defense priming prepares offspring for faster responses to herbivore and pathogen attacks.
Area of Science:
- Plant biology
- Ecology
- Evolutionary biology
Background:
- Plant defense induction by herbivore and pathogen attack was traditionally viewed as a within-generation phenomenon.
- Emerging evidence indicates that defense phenotypes can be inherited across plant generations.
Purpose of the Study:
- To review the evidence for transgenerational defense induction in plants.
- To explore the mechanisms and ecological implications of this phenomenon.
Main Methods:
- Review of existing scientific literature on plant defense mechanisms.
- Analysis of studies demonstrating transgenerational inheritance of defense traits.
- Examination of epigenetic modifications (DNA methylation, histone modifications, small RNAs) involved in defense priming.
Main Results:
- Transgenerational defense induction is a widespread phenomenon across various plant species.
- Epigenetic mechanisms like DNA methylation, histone modifications, and small RNAs mediate this inheritance.
- Induced defenses can persist for multiple generations and prime offspring for enhanced responses.
Conclusions:
- Transgenerational defense induction significantly impacts plant-herbivore and plant-pathogen interactions.
- Understanding the predictability and detectability of these inherited defenses is crucial for ecological and evolutionary studies.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
