Crop Improvement
Faster, cheaper ways to study plant genes mean researchers can more quickly develop crops that resist drought, disease, or pests — directly benefiting the food on your plate and the plants in your garden.
When scientists want to understand what a specific gene does in a plant, they often need to temporarily 'switch it on' in the plant to watch what happens. VAST is a new technique that uses vacuum suction and ultrasonic sound waves to push genetic material into plant seedlings much more efficiently than before. It works on many different kinds of plants — both grasses like wheat and corn, and flowering plants like tomatoes — making it a versatile tool for plant research.
Key Findings
VAST combines vacuum infiltration and sonication pretreatments to substantially increase the efficiency of transient gene expression compared to existing methods.
The method is effective across diverse plant groups, including both monocots (e.g., grasses and cereals) and eudicots (e.g., most flowering plants), broadening its applicability.
Systematic optimization of plant growth conditions was a key factor in achieving consistent, high-efficiency transformation across species.

Scientists developed VAST, a faster and more reliable method to temporarily introduce genes into plant seedlings using vacuum pressure and sound waves. This tool works across a wide range of plant types, accelerating research into how plants grow, defend themselves, and respond to stress.
