  "account": "A groundbreaking study reveals that dry plant seeds preserve fully formed mitochondria, enabling rapid energy production during germination. Despite losing 90% of their water content, seeds enter a dormant state, resembling raisins compared to grapes. Upon rehydration, mitochondria swiftly resume cellular respiration, providing the necessary energy for growth. Researchers from the Universities of Münster, Hanover, and Halle in Germany examined thale cress (Arabidopsis thaliana) mitochondria and discovered that they maintain a fully developed structure with all required proteins for respiration. This rapid activation of mature mitochondria is a shared feature among plants with orthodox seeds, including rapeseed, millet, and tomato. Understanding the proteins involved in mitochondria survival during dry conditions could potentially lead to improved seed longevity and enhanced resistance to unfavorable storage conditions.",
  "summary": "The majority of plant seeds have the special ability to almost completely dry out and yet remain viable. While most living cells die with a 90% loss of water, cells in seeds enter a biological state of dormancy. With a moisture content of less than 10%—similar to a raisin compared to a grape—they become small time capsules and can lie dormant for decades until they are awakened by favorable…",
