Chris Walters, Research Leader of the Plant Germplasm Preservation Research team at USDA-ARS National Laboratory for Genetic Resources Preservation Knowing how long storedgermplasmsurvives is critical for effective banking of genetic resources. Longevity is inherently difficult to predict because there are so many factors controlling how cells respond to storage conditions. Uncertainty increases forgermplasmcollections of natural […]
