脂壳低聚糖 (LCO) 是由根瘤菌产生的信号分子，可触发豆科植物的结瘤过程，也由一些与植物建立共生关系的真菌（特别是丛枝菌根真菌和外菌根真菌）产生。在这里，我们证明许多其他真菌也产生 LCO。我们测试了代表大多数真菌门的 59 个物种，发现 53 个物种产生的 LCO 可以通过功能测定和/或质谱法检测到。 LCO 处理影响子囊菌和担子菌门非共生真菌的孢子萌发、菌丝分支、假菌丝生长和转录。我们的研究结果表明，LCO 的产生在真菌中很常见，并且 LCO 可能作为调节真菌生长和发育的信号。脂壳寡糖 (LCO) 是某些细菌和真菌产生的信号分子，与植物建立共生关系。在这里，作者表明，许多其他非共生真菌也产生 LCO，并调节真菌的生长和发育。
Lipo-chitooligosaccharides (LCOs) are signaling molecules produced by rhizobial bacteria that trigger the nodulation process in legumes, and by some fungi that also establish symbiotic relationships with plants, notably the arbuscular and ecto mycorrhizal fungi. Here, we show that many other fungi also produce LCOs. We tested 59 species representing most fungal phyla, and found that 53 species produce LCOs that can be detected by functional assays and/or by mass spectroscopy. LCO treatment affects spore germination, branching of hyphae, pseudohyphal growth, and transcription in non-symbiotic fungi from the Ascomycete and Basidiomycete phyla. Our findings suggest that LCO production is common among fungi, and LCOs may function as signals regulating fungal growth and development. Lipo-chitooligosaccharides (LCOs) are signaling molecules produced by certain bacteria and fungi that establish symbiotic relationships with plants. Here, the authors show that LCOs are produced also by many other, non-symbiotic fungi, and regulate fungal growth and development.
