Rice (Oryza sativa L.) cultivated in the Central Highlands of Vietnam: Dataset on the endophytic microbiome

Abstract

Rice (Oryza sativa L.) is the main annual crop cultivated in the Central Highlands region of Vietnam. Understanding the endophytic bacterial community of this plant, a new technique for sustainable production can be developed. In this work, a representative sample was obtained by combining rice (RVT variety) root samples collected from five different fields in Dray Sap Commune, Krong Ana District, Dak Lak Province, the Central Highlands of Vietnam. Using the Illumina MiSeq technology, the 16S rRNA metagenomics was applied to the sequencing amplicons library. The QIIME2 matched with the SILVA SSURef reference database was employed to analyze the taxonomic profile, and the PICRUSt2 and MetaCyc databases were used to predict the functional profile of rice endophytic prokaryotes. Results revealed that Enterobacterales was the most predominant class (57.7%) in the bacterial community, and biosynthesis was the primary function of the rice endophytic microbiome (75.95%). Raw sequences obtained in this work are available from the National Center for Biotechnology Information (NCBI) (Bioproject ID: PRJNA994482) and Mendeley Data [1]. Data in this work provide insight into the endophytic microbiome of rice (RVT variety) cultivated in the Central Highlands of Vietnam. These data are valuable for developing a new method for producing locally sustainable rice employing endophytic bacteria. This is the first report on the endophytic microbiome of rice cultivated in this region.
