With the rapid development of molecular biotechnology, transcriptomics has been widely used in the study of gene expression. In recent years, the techniques for microbial transcriptomics research have also been rapidly developing. At the gene level, the way for obtaining sequence information has been developed from complementary validation of RNA fragment through DNA microarray to direct sequencing of full-length RNA. Spatially, the traditional population transcriptomics technique has been developed into spatial, single cell and epigenetic transcriptomics studies. With the application of transcriptomics techniques in the field of microbial research, the corresponding defects were gradually revealed and constantly improved. In this paper, the traditional and new transcriptomics techniques in the field of microbial research are summarized to provide reference for microbial transcriptomics research.
