Development of CRISPR-Cas9-Based Genome Editing Tools for Non-model Microorganism Erwinia persicina

Synthetic and Systems Biotechnology, Journal Year: 2025, Volume and Issue: 10(2), P. 555 - 563

Published: Feb. 19, 2025

Erwinia persicina is a bacterium that has been known to produce secondary metabolites, such as andrimid, pink pigment, and exopolysaccharides, infect more than twenty plant species. However, traditional gene manipulation methods have hindered by the inefficient of suicide plasmid-mediated genome editing. In this study, we describe successful application CRISPR-Cas9 system in E. persicina. Efficient editing was achieved substituting native gRNA promoter with J23119 single-plasmid (pRed_Cas9_ΔpoxB) optimizing design. The use double gRNAs led deletion 42 kb genomic fragment, incorporation sacB screening marker facilitated iterative knockouts. Additionally, 22 plasmid containing self-resistance conjugally transferred into persicina, resulting insertion 6.4 fragment 100 % efficiency. Furthermore, demonstrated expression shinorine, an anti-UV compound, within chassis. This study establishes promising chassis for synthetic biology provides model gene-editing systems non-model microorganisms.

Extremophiles are organisms that can survive and thrive in conditions termed as "extreme" by human beings. Conventional methods cannot be applied under extreme like temperature pH fluctuations, high salinity, etc. for a variety of reasons. function adapted to these environments sustainable, cheaper, efficient, therefore, they serve better alternatives the traditional methods. They adapt with biochemical physiological changes produce products extremolytes, extremozymes, biosurfactants, etc., which found useful wide range industries sustainable agriculture, food, cosmetics, pharmaceuticals. These also play crucial role bioremediation, production biofuels, biorefinery, astrobiology. This review paper comprehensively lists out current applications extremophiles their various explores prospects same. help us understand underlying basis biological mechanisms exploring boundaries life thus origin evolution on Earth. helps research extra-terrestrial space exploration. The structure properties along any possible long-term effects need investigated further.

Published: April 13, 2023

Ultraviolet radiation (UVR) has been scientifically proven to cause skin disorders such as sunburn, cancer and the symptoms of chronic exposure. Natural sun screening compounds have recently gained tremendous attention from cosmetic cosmeceutical sectors for treating hyperpigmentation aging. A wide range natural UV-absorbing used replace or reduce number synthetic sunscreen molecules. One primary causes photoaging is DNA damage, mainly caused by UVR. Photoprotection provided traditional sunscreens purely preventative no efficacy after damage initiated. As a result, quest DNA-repair mechanisms that block, reverse, postpone pathologic processes in UV-exposed stimulated anti-photoaging research methods increase effectiveness sunscreens. This review summarizes many microalgae, lichens, plants demonstrated potential photoprotection effects against UV radiation-induced damage. Furthermore, it offers an overview current breakthroughs enzymes utilized their influence on photoaging.
