The anti‐CRISPR protein AcrIE8.1 inhibits the type I‐E CRISPR‐Cas system by directly binding to the Cascade subunit Cas11

open access: yesFEBS Letters, EarlyView.
In this study, we present the structure of AcrIE8.1, a previously uncharacterized anti‐CRISPR protein that inhibits the type I‐E CRISPR‐Cas system. Through a combination of structural and biochemical analyses, we demonstrate that AcrIE8.1 directly binds to the Cas11 subunit of the Cascade complex to inhibit the CRISPR‐Cas system.

Coumarin Inhibits Primary Root Growth by Modulating Auxin Signaling via Neddylation

open access: yesBiology
The allelopathic compound coumarin inhibits root growth across numerous species, but its mechanism is unknown. Through a genetic screen in Arabidopsis mutants, we identified the mutants for AXR1 (AUXIN RESISTANT 1) and ECR1 (E1 C-TERMINAL RELATED 1), two

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Different invasibility of permanent and temporary waterbodies in a semiarid Mediterranean Island [PDF]

open access: yes, 2019
Nonindigenous species (NIS) represent a threat to aquatic biodiversity worldwide. However, freshwater ecosystems in drylands are potentially more prone to biological invasions than those located in temperate regions because of the higher number of ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Could biological invasion by Cryptostegia madagascariensis alter the composition of the arbuscular mycorrhizal fungal community in semi-arid Brazil?

open access: yes, 2016
Biological invasions pose a serious threat to native semi-arid areas of Brazil, especially in areas of the state of Ceara that are typically invaded byCryptostegia madagascariensis, an exotic plant species from Madagascar.

Biological Invasions, Climate Change, and Genomics [PDF]

open access: yesEvolutionary Applications, 2014
AbstractThe rate of biological invasions is expected to increase as the effects of climate change on biological communities become widespread. Climate change enhances habitat disturbance which facilitates the establishment of invasive species, which in turn provides opportunities for hybridization and introgression.
