| 1 | Host Genetic Background Impacts Microbiome Composition in Newborn Alligator显示文摘Genetic factors play a key role in determination of the structure of the cloacal flora for newborn Chinese Alligators.We collected the cloacal microbiomes for 24 newborn Chinese Alligators from three different genetic backgrounds for 16S gene amplicon sequencing.The number of cloacal flora for the Chinese Alligators from different groups was comparable but differed structurally.There were variations in proportions of floral compositions at the phylum and family levels;however,the main difference was at the genus level.There were two significant differences in richness and evenness among the three groups.Non-metric multidimensional scaling NMDS analysis revealed that the 24 samples could be clearly divided into three categories based on their genetic backgrounds(stress=0.0244).Thus,we postulated that newborn Chinese Alligators with different genetic backgrounds have different immune strengths,which affects individual responses to environmental microorganisms.In summary,newborn Chinese Alligators from different genetic backgrounds exhibit variations in cloacal microbiome. | Huabin ZHANG Wengang LI Genjun TU Ke SUN Liuyang YANG Ziyi WANG Zirui WU Yongkang ZHOU Song ZHANG Hao SUN Changshun SHENG Xiaoping WANG Rongjun ZHANG Xiaobing WU Tao PAN | 2023 | Asian Herpetological Research2023，14，3： | 0 |
