As the next-generation sequencing standardized panel for ctDNA detection emerges, its clinical utility needs to be validated. We prospectively recruited 184 resectable lung cancer patients from four medical centers.

Role of carbohydrate-active enzymes in mycorrhizal symbioses.

Mycorrhizal fungi form mutually beneficial interactions with a wide range of terrestrial plants. During this symbiosis, the associated fungus provides mineral nutrients, such as phosphorus and nitrogen, to its host plant in exchange of photosynthesis-derived carbohydrates. Genome sequencing of mycorrhizal fungi has shown that arbuscular mycorrhizal fungi and ectomycorrhizal fungi have a restricted set of plant-cell wall degrading enzymes (PCWDE) genes, while orchid and ericoid mycorrhizal fungi have an extended PCWDE repertoire similar to soil decomposers and wood-decay fungi.
