Summary:Holcoglossum kimballianum is a rare and endangered orchid, and its wild populations are in urgent need of conservation. Endophytic fungi and bacteria are important to the growth and development of orchids. In order to assess the diversity of H. kimballianum endophytes and the impact of sampling methods on the endophytes, high-throughput sequencing technology was used to study the diversity of endophytes in fresh and silica gel-dried roots of H. kimballianum in ex-situ conservation. The results were as follows: (1) The species compositions of endophytic fungi and endophytic bacteria were distinctly different in fresh and silica gel-dried roots of H. kimballianum. There were total of 6 phyla 46 families 51 genera of endophytic fungi and 15 phyla 105 families 178 genera of endophytic bacteria annotated in the roots of the H. kimballianum. After silica gel-dried, the endophytic fungi of the H. kimballianum had total of 6 phyla, 88 families, 116 genera, and the endophytic bacteria had total of 21 phyla, 154 famili
