Climate Adaptation
Seeds behind 70% of the food on your plate are under threat from climate change, and this research is building the roadmap to make them more resilient — from the wheat in your bread to the tomatoes in your garden.
Researchers took a deep dive into seeds using a suite of cutting-edge tools that can read a seed's genetic activity, proteins, and chemistry all at once — even cell by cell. They discovered new types of cells inside seeds and mapped out the chemical signals that tell a seed when to stay dormant and when to wake up and grow. This knowledge gives plant breeders precise targets to create crops that can handle drought, heat, and other stresses caused by a changing climate.
Key Findings
Seeds supply approximately 70% of the global food supply, making their resilience to climate stress a critical food security issue.
Single-cell and spatial analysis technologies revealed previously unknown cell types and tissue-specific control mechanisms within seeds.
Key molecular networks — including phosphorylation signaling, metabolic shifts, and hormone activity — were identified as central regulators of dormancy and germination.

Scientists have used powerful molecular analysis tools to map the hidden machinery controlling how seeds develop, go dormant, and sprout — discoveries that could help breed crops better suited to a changing climate.
