Parasitic plants like dodder transfer biomolecules, including mRNA and proteins, to host plants, altering their functions. This interplant signaling impacts plant physiology and ecology.
Area of Science:
- Plant Biology
- Ecology
- Molecular Biology
Background:
- Parasitic plants rely on hosts for resources via haustoria.
- Interplant transfer of biomolecules (systemic signals, mRNA, sRNAs, proteins) occurs between parasitic and host plants.
- These transferred molecules can alter recipient plant physiology and ecology.
Purpose of the Study:
- To review interplant systemic signaling between hosts and dodder (Cuscuta).
- To explore the physiological and ecological functions of these signals.
- To discuss the mechanisms and functions of transferred macromolecules like mRNA, sRNAs, and proteins.
Main Methods:
- Literature review of studies on parasitic plant-host interactions.
- Analysis of research on systemic signaling pathways.
- Examination of molecular mechanisms for macromolecule transfer.
Main Results:
- Dodder actively transfers various biomolecules to host plants.
- Transferred molecules, including mRNA, sRNAs, and proteins, can modify host plant functions.
- Interplant signaling influences plant physiology and ecological interactions.
Conclusions:
- Interplant communication via biomolecule transfer is a significant aspect of parasitic plant-host relationships.
- Understanding these molecular exchanges is crucial for comprehending plant ecology and evolution.
- Further research is needed to fully elucidate the mechanisms and impacts of dodder-mediated interplant signaling.

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...
