Soil microbiome dataset from Yok Don national park in the Central Highlands region of Vietnam

The Central Highlands region contains most of the national parks in Vietnam with different ecosystems, including the national parks of Kon Ka Kinh, Chu Mon Ray, Chu Yang Sin, Yok Don, Bidoup-Nui Ba, and Ta Dung. Thus, this region is considered a center with the highest biodiversity in Vietnam [1]. Among the national parks, Yok Don is unique in its conservation of the dry deciduous dipterocarp forest. Furthermore, Yok Don is the second-largest park in Vietnam; it has the most different ecosystem compared with other national parks in this region [2]. Although some studies have investigated biodiversity preservation in the region, some other studies have only dealt with medicinal plants, lichens, and the rhizospheric bacteria of cultivated black pepper [1,[3], [4], [5]. To the best of our knowledge, no research on the microbial communities in Yok Don national park and in the Central Highlands has been reported. At present, global warming and a decrease in the forest area in the Central Highlands have led to the ongoing reduction in biodiversity and microbial resources. The current study reports the microbiome dataset from the soil sample collected in Yok Don national park. Metagenomic next-generation sequencing was used to characterize the microbial communities in the sample. The metagenome dataset generated provides information on microbial diversity and its functionality and can be useful for further studies on the conservation and use of microbial genetic resources in this region.

Value of the Data
• The data generated provides information on the microbiome in the soil at Yok Don national park in the Central Highlands, Vietnam. • The data could be useful for the comparative analysis of the taxonomic profiles of Yok Don national park with those of other national parks. • The data could be useful for future studies on the conservation and use of indigenous microbial gene resources for sustainable crop production and related fields.

Sample collection
A 5-30 cm deep soil sample (about 300 g) was collected from Yok Don national park in the Central Highlands, Vietnam, kept at 4 °C, and transported to the laboratory within 2 h. The sample was stored at −80 °C until analyzed.

DNA extraction and the 16S rRNA gene amplicon sequencing
DNA was extracted from 0.3 g of the soil sample using the DNeasy PowerSoil kit (Qiagen, Germany). The V1-V9 region of the 16S rRNA gene was amplified from the extracted DNA. Libraries of the 16S rRNA gene amplicon were prepared using the Swift amplicon 16S plus internal transcribed spacer panel kit (Swift Biosciences, USA) according to the manufacturer's instructions. The 16S rRNA gene amplicon sequencing was performed using the Illumina MiSeq platform (2 × 150-bp paired ends). Primers used for amplification are shown in Table 2 .
