Identification of EppR, a Second Repressor of Error‐Prone DNA Polymerase Genes in Acinetobacter baumannii

open access: yesMolecular Microbiology, EarlyView.
A novel TetR‐like regulator (EppR) has been identified to repress genes encoding DNA polymerase V in Acinetobacter baumannii through the direct binding of a conserved EppR motif in their promoters. EppR works with previously identified regulator UmuDAb to serve as co‐regulators of these genes. In response to DNA damage and/or environmental stress, both

Staphylococcus aureus COL: An Atypical Model Strain of MRSA That Exhibits Slow Growth and Antibiotic Tolerance due to a Mutation in PRPP Synthetase

open access: yesMolecular Microbiology, EarlyView.
COL is an unusual “model” strain of Staphylococcus aureus that exhibits slow growth and multidrug antibiotic tolerance. This phenotype is primarily due to a mutation in Prs, which synthesizes the core metabolite phosphoribosyl pyrophosphate (PRPP). Introduction of the COL Prs allele into the antibiotic‐susceptible strain Newman confers tolerance, while

Co‐transformation using T‐DNA genes from Agrobacterium strain 82.139 enhances regeneration of transgenic shoots in Populus

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Barriers to transformation and regeneration continue to hamper the application of recombinant DNA‐based biotechnologies in most crops, including for gene editing. To tackle this problem, there has been increasing interest in morphogenic regulator genes, which aid in regeneration and are often plant developmental master regulator genes.

Application of a GRF‐GIF chimera enhances plant regeneration for genome editing in tomato

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Genome editing has become a routine tool for functionally characterizing plant and animal genomes. However, stable genome editing in plants remains limited by the time‐ and labour‐intensive process of generating transgenic plants, as well as by the efficient isolation of desired heritable edits.
