Dynamic Changes of Gut Microbial Communities of Bumble Bee Queens through Important Life Stages.

abstract：:Microbial and plant specialized metabolites, also known as natural products, are key mediators of microbe-microbe and host-microbe interactions and constitute a rich resource for drug development. In the past decade, genome mining has emerged as a prominent strategy for natural product discovery. Initially, such minin...
