Deciphering Aspergillus section Terrei in Galleria mellonella model: a clade-specific pathogenicity characterization

Microbiology Spectrum
The Aspergillus genus encompasses a diverse array of species, some of which are opportunistic pathogens. Traditionally, human aspergillosis has primarily been linked to a few Aspergillus species, predominantly A. fumigatus.

Species of Botryosphaeriaceae occurring on Proteaceae [PDF]

, 2008
The Botryosphaeriaceae includes several species that are serious canker and leaf pathogens of Proteaceae. In the present study, sequence data for the ITS nrDNA region were used in conjunction with morphological observations to resolve the taxonomy of ...

Transcription Factor Promiscuity Drives Regulatory Rewiring and Evolvability in Gene Networks in Bacteria

Advanced Science, EarlyView.
When a master transcription factor (TF) is lost, bacteria can rapidly rewire gene regulatory networks by co‐opting related regulators. Using experimental evolution in Pseudomonas fluorescens, we show that TF promiscuity (low‐level, non‐cognate binding) provides the raw material for rewiring. Successful co‐option follows a predictable hierarchy governed

Scalable ω‐Substituted α‐Olefins via Living Chain Transfer Telomerization: A Platform for Next Generation Polyolefins

Angewandte Chemie, EarlyView.
A highly versatile and general strategy is presented for the scalable production of practical quantities of ω‐substituted α‐olefins using tris(ω‐substituted alkyl)aluminum telogens that are readily available through a “green” synthesis from commodity triisobutylaluminum and ethene as the taxogen. These new α‐olefins can be designed and used as monomers

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

Advanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

Atypical Condensation Domains Guide Discovery and Illuminate Biosynthesis of Myxoglucamides Featuring Vinyl‐Substituted, α‐Oxidized γ‐Amino Acids

Angewandte Chemie, EarlyView.
Genome mining of atypical condensation (C) domains leads to the discovery of myxoglucamides, glycolipopeptides featuring an unprecedented vinyl‐substituted, α‐oxidized γ‐amino acid. Biosynthetic studies reveal a discrete C‐domain‐like O‐acyltransferase, a β‐hydroxylation‐dependent chain‐extension checkpoint, and an unusual pathway for γ‐amino acid ...

Diversity and environmental relations of cryptic, systemic Botrytis infections in symptomless hosts.

Frontiers in Plant Science, 2016
Botrytis species are generally considered to be aggressive, necrotrophic plant pathogens. By contrast to this general perception, however, Botrytis species could frequently be isolated from the interior of multiple tissues in apparently healthy hosts of ...
