Vitamin B₁₂ is synthesized exclusively by bacteria and archaea, yet duckweeds accumulate bioavailable B₁₂ despite lacking the capacity to produce or use it. We asked how this function is organized within the duckweed microbiome, and whether cultivation conditions could enhance it.
Bioavailable B₁₂ was detected across rooted and rootless duckweed genera, and in additional aquatic plants. Among...
Potential cobalamin (vitamin B12)-producing Wolffia globosa-associated bacteria were investigated through shotgun metagenomic sequencing analysis. Taxonomic classification assigned microbiomes consisting of 5 phyla, 8 classes, 36 families, and 68 genera. High-quality metagenome-assembled genomes (MAGs) were assigned to Allorhizobium sp., Alsobacter sp., Bosea sp., Bradyrhizobium...
Duckweeds are small, fast-growing aquatic plants that provide a useful model for studying plant–microbiome interactions in aquatic environments. Among them, Spirodela polyrhiza is particularly interesting because it can switch from active vegetative growth to dormant turion formation (starch-rich vegetative propagules), in a turion–plant–turion cycle that allows to examine plant-associated...
In duckweed pond systems established either for biofiltration or biomass production, excessive proliferation of planktonic algae reduces ecosystem services. In this study we revealed those algal related mechanisms resulting duckweed growth inhibition. We isolated 26 algal species from duckweed covered mesocosms and measured their impact on axenic culture of Lemna gibba. At low duckweed...
