Comparative transcriptomics and metabolomics provide insight into degeneration-related physiological mechanisms of Morchella importuna after long-term preservation.
Article in Microbial biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ascomycetes fungi are often prone to degeneration. Agricultural production of the prized ascomycete mushroom Morchella importuna (black morel) typically suffers from reduced yield and malformed ascocarps owing to culture degeneration. This study compared M. importuna cultures subjected to five different long-term preservation treatments, using transcriptomics and metabolomics. Avoiding repeated subculturing in combination with nutrient-limited conditions was found to be the most beneficial method for maintaining the fruiting capability of morels. The expression of the gene sets involved in cysteine and methionine metabolism and nucleocytoplasmic transport was upregulated under nutrient-limited and nutrient-rich conditions, respectively. This increased expression was accompanied by differential accumulation of metabolites involved in nucleobase metabolism. Repeated subculturing triggered dissimilar changes in the functional modules under nutrient-rich and nutrient-limited conditions. A diverse set of cellular biochemical processes related to carbon metabolism were altered by repeated subculturing under nutrient-rich conditions, whereas glycerophospholipid and purine metabolism were key functions affected by repeated subculturing under nutrient-limited conditions. Altogether, metabolic alterations related to sulfur-containing amino-acid biosynthesis, DNA repair, and cellular structural maintenance contributed to improved preservation outcomes in terms of morel fruiting capability. Our findings contribute to a more detailed understanding of the molecular mechanisms related to subculturing and fruiting of ascomycete macrofungi after long-term preservation.
