**2. Applications of RNA-seq**

Understanding the transcriptome is essential to knowledge of the functional genomics of an organism. The development of next-generation sequencing (NGS) impacts different areas, such as medical and industrial, and has gone through a revolutionary process. Different approaches, among them the RNA-seq technique, have emerged in the fields of microbiology and molecular biology in order to aid in understanding and bring solutions to bacterial domain investigations. In this section, we will detail some applications that are part of our current context.
