Artificial Endosymbiosis of Pedobacter sp. DDGJ Boosts the Growth Potential, Stress Resistance and Productivity of Morchella Mushrooms.
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 5 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
True morels are precious edible and medicinal mushrooms. The sustainable development of morel cultivation necessitates urgent breeding programmes to develop improved varieties or strains. Some soil bacteria, including Pedobacter spp., are recognised as morel's beneficial microbes. In this paper, the potential beneficial bacterium Pedobacter sp. DDGJ with minor chitinolytic activity was isolated and confirmed for improving morel's mycelial growth and identified using a combination of morphological characteristics, 16 S rRNA gene sequencing, and comparative genomics. Then, it was introduced into the hyphal cells of three cultivated Morchella strains (M. sextelata 13, M. eximia SM, and M. importuna Y2) through a confrontation culture method. The successful establishment of artificial endosymbiosis was confirmed by PCR assay, green fluorescent protein gene (gfp) localisation, and the cryo-preparation system conjunction with high-resolution field emission scanning electron microscopy. Laboratory assay indicated that artificial endosymbiosis of the bacterium significantly enhanced morel's growth potential, resistance to allelochemicals of 4-coumaric acid and antagonistic capability against the pathogenic fungus Fusarium oxysporum and soil-dominant fungus Chaetomium globosum. Moreover, the outdoor planting experiment showed significant increase in productivity among the endosymbiotic morel strains. The study provides an additional tool to improve Morchella strains with high yield and strong stress resistance.
