Overcoming arabidopsis seed dormancy with cold plasma: the role of cytoplasmic glass transition

What is it about?

This article investigates the use of cold atmospheric plasma (CAP) as a novel method for breaking the dormancy of Arabidopsis thaliana seeds, a process that typically takes place over several months and is known as post-maturation. The study explores the effect of CAP on the germination process by manipulating seed water content and applying heat during treatment. Differential scanning micro-calorimetry is used to demonstrate that the transition of seed cytoplasm from a glassy to a rubbery state enhances the impact of CAP, proposing that this reduces cytoplasmic viscosity and promotes oxidative signaling, thereby improving germination.

Why is it important?

The importance of this article lies in the fact that it could revolutionize agricultural practices by providing a method for rapidly lifting seed dormancy using CAP. By understanding the relationship between CAP treatment and the cytoplasmic state of the seed, research could significantly shorten the post-maturation period required for seed germination. This could have far-reaching implications for agricultural production, enabling farmers to plan and undertake crops more efficiently. In addition, the research results provide valuable insights into the fundamental biology of seed dormancy and germination, offering a scientific basis for future technological advances in seed treatment.
