Plant grafting induces inheritable genetic variation through horizontal gene transfer. Genetic material moves via plasmodesmata and phloem, with non-coding RNAs mediating epigenetic changes for stress adaptation.
Area of Science:
- Plant Biology
- Genetics
- Epigenetics
Context:
- Plant grafting is a widespread horticultural practice.
- The mechanisms underlying graft-induced inheritable variation remain incompletely understood.
- Recent research highlights horizontal gene transfer between stock and scion.
Purpose:
- To review recent advances in understanding graft-induced genetic variation.
- To elucidate the mechanisms of genetic material transport in grafted plants.
- To explore the role of non-coding RNAs in epigenetic modifications and stress adaptation.
Summary:
- Genetic information is horizontally transferred between stock and scion in grafted plants.
- Transport occurs through plasmodesmata and phloem, influencing scion growth and development.
- Non-coding RNAs play a role in epigenetic modifications, aiding plant adaptation to grafting stress.
Impact:
- Provides a comprehensive overview of current research on graft-induced genetic variation.
- Enhances understanding of molecular mechanisms governing plant responses to grafting.
- Offers insights into epigenetic regulation and plant adaptation strategies.

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...
