摘      要：Gut microbiota plays a critical role in host physiology and *** coevolution between the host and its gut microbes facilitates animal adaptation to its specific ecological *** factors such as host diet and phylogeny modulate the structure and function of gut ***,the relative contribution of each factor in shaping the structure of gut microbiota remains *** giant(Ailuropoda melanoleuca)and red(Ailurus styani)pandas belong to different families of order *** have evolved as obligate bamboo-feeders and can be used as a model system for studying the gut microbiome convergent ***,we compare the structure and function of gut microbiota of the two pandas with their carnivorous relatives using 16S rRNA and metagenome *** found that both panda species share more similarities in their gut microbiota structure with each other than each species shares with its carnivorous *** indicates that the specialized herbivorous diet rather than host phylogeny is the dominant driver of gut microbiome convergence within *** analysis revealed that the symbiotic gut microbiota of both pandas possesses a high level of starch and sucrose metabolism and vitamin B12 *** findings suggest a diet-driven convergence of gut microbiomes and provide new insight into host-microbiota coevolution of these endangered species.
