Hidden allies: Seed microbiome diversity and its potential in early plant development and stress resilience

Seeds are essential for plant growth, but they are not alone. They carry tiny microorganisms, including bacteria, that can influence how well seeds germinate and young plants grow, especially under challenging conditions such as drought and high salt levels.

In this PhD research, I investigated how these microorganisms become associated with seeds, how they are passed from one plant generation to the next, and how growing conditions influence their diversity. I also compared seeds collected from wild plants with those grown in greenhouses to understand differences in their microbial communities.

My research showed that some seed-associated bacteria release natural gases, known as volatile compounds, that can help seeds germinate and young plants grow better under stressful conditions. Seeds from wild plants also provide a valuable source of potentially beneficial microorganisms.

These findings highlight the hidden role of microorganisms in seed health and their potential to improve crop growth and resilience, contributing to more sustainable agriculture.
