Comparative transcriptomics and metabolomics provide insight into degeneration-related physiological mechanisms of Morchella importuna after long-term preservation

mycolabadmin

This research studied how to best preserve morel mushroom cultures for long periods without them losing quality. Scientists compared five different storage methods over 7 years and found that storing cultures in nutrient-poor conditions without repeatedly replicating them produced the healthiest mushrooms. The study identified specific genes and metabolic processes that stayed healthy under the best preservation method, offering farmers better ways to maintain morel quality for cultivation.

Biophysical Manipulation of the Extracellular Environment by Eurotium halophilicum

mycolabadmin

Eurotium halophilicum is a remarkable fungus found on old books that can survive in extremely dry conditions by using salt crystals to pull water from the air. The fungus covers itself with hair-like structures and produces sticky polymers that help it maintain moisture. This ability to thrive in seemingly dry environments makes it a challenge for museums and libraries trying to preserve old books, and climate change may make this problem worse.

Esterase and Peroxidase Are Involved in the Transformation of Chitosan Films by the Fungus Fusarium oxysporum Schltdl. IBPPM 543

mycolabadmin

Researchers discovered that a common fungus called Fusarium oxysporum can modify chitosan films in unique ways without destroying them. The fungus produces special enzymes (esterase and peroxidase) that strengthen and reorganize the chitosan material, making it more resistant to dissolution and better suited for practical applications like drug delivery or water purification.

Chalkbrood Disease Caused by Ascosphaera apis in Honey Bees (Apis mellifera)—Morphological and Histological Changes in Infected Larvae

mycolabadmin

Chalkbrood is a serious fungal disease that kills honeybee larvae, caused by the fungus Ascosphaera apis. This study examined exactly how the infection progresses by infecting larvae in controlled laboratory conditions and observing them over time under a microscope. The researchers found that once infected, larvae die very quickly within 3-7 days as the fungus spreads throughout their bodies, and the fungus continues to grow even after the larvae are dead, eventually forming visible spores on the dead larvae that spread the disease to other bees in the colony.
