Abstract

Cyanobacteria are an ideal host for biofuel production. Although efforts have been made to genetically engineer cyanobacteria for efficient production of biofuels and other important chemicals, the tools that can be applied to cyanobacteria are still limited. A new gene regulation tool, riboregulator, has been examined for application in cyanobacteria. A riboregulator is a nature-inspired RNA tool, which is composed of two artificially designed RNA fragments. Owing to its high specificity and efficacy, it is suitable for metabolic engineering in cyanobacteria, and several studies have been done to optimize and improve the function of the riboregulator. In this review, we focus on the recent improvements made to riboregulators and compare them with other RNA-mediated gene regulation tools developed in cyanobacteria to investigate future applications of riboregulators.

Biofuels (ASM)

Biofuels are produced through contemporary processes from biomass rather than geological processes involved in fossil fuel formation. Examples include biodiesel, green diesel, biogas, etc. Discover the latest research on biofuels in this feed.

CRISPR (general)

Clustered regularly interspaced short palindromic repeats (CRISPR) are DNA sequences in the genome that are recognized and cleaved by CRISPR-associated proteins (Cas). CRISPR-Cas system enables the editing of genes to create or correct mutations. Discover the latest research on CRISPR here.
