DOI: 10.1080/09670262.2020.1744039
Abstract: ABSTRACT Iron is one of the most abundant elements on Earth, and it is essential for life. Despite the abundance of iron, its chemistry leads to very limited bioavailability, which has resulted in the evolution… read more here.

DOI: 10.1093/nar/gkac137
Abstract: Abstract Burkholderia cenocepacia is an opportunistic pathogen that causes severe infections of the cystic fibrosis (CF) lung. To acquire iron, B. cenocepacia secretes the Fe(III)-binding compound, ornibactin. Genes for synthesis and utilisation of ornibactin are… read more here.

DOI: 10.1111/1462-2920.14079
Abstract: In nature, microorganisms are exposed to multiple stress factors in parallel. Here, we investigated the response of the model cyanobacterium Synechocystis sp. PCC 6803 to simultaneous iron limitation and osmotic stresses. Iron is a major… read more here.

DOI: 10.1128/aac.00592-21
Abstract: Transporters belonging to the resistance-nodulation-division (RND) superfamily of proteins are invariably present in the genomes of Gram-negative bacteria and are largely responsible for the intrinsic antibiotic resistance of these organisms. The numbers of genes encoding… read more here.

DOI: 10.3389/fmicb.2018.02689
Abstract: In this work, we used comparative transcriptomics to identify regulatory outliers (ROs) in the human pathogen Candida glabrata. ROs are genes that have very different expression patterns compared to their orthologs in other species. From… read more here.

DOI: 10.3389/fmicb.2022.978859
Abstract: Pathogens such as Staphylococcus aureus must overcome host-induced selective pressures, including limited iron availability. To cope with the harsh conditions of the host environment, S. aureus can adapt its physiology in multiple ways. One of… read more here.
