Researchers identify protein chain that triggers plant growth changes after touch
A team at Lund University published findings in Nature Communications explaining how Arabidopsis thaliana activates a specific protein pathway within a minute of mechanical stimulation.
Mechanical stimulus activates proteins quickly
Scientists subjected the small flowering weed Arabidopsis thaliana to various forms of physical contact. A chain of three specific proteins known as MAP kinases becomes activated within one minute. This rapid response sends signals that influence the activity of hundreds of genes.
Gene activity drives growth changes
The resulting signals contribute to observable changes in how the plant grows and develops. Researchers combined genetic, molecular, and large-scale analyses to track these internal processes. The study identifies a missing piece of the puzzle regarding how touch links to development.
