Advanced Science, EarlyView.This study proposes a novel model illustrating how quorum sensing (QS) regulates the type III‐A CRISPR‐Cas system in Staphylococcus aureus. The QS regulator AgrA suppresses CRISPR‐Cas activity by downregulating the transcriptional regulators SarA and ArcR.

Advanced Science, EarlyView.The most elaborate known example of β‐oxidation‐like pathway recruitment in fungi is reported, involving a 10‐step oxidative chain‐shortening cascade catalyzed by five dedicated enzymes to generate the pharmacophore of mycophenolic acid (MPA)—a novel clinical immunosuppressant. Our findings illustrate how nature repurposes catabolic enzymes for complex

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas
American Journal of Botany, EarlyView.Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Does the abiotic environment influence the distribution of flower and fruit colors?
American Journal of Botany, EarlyView.Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Animal Models and Experimental Medicine, EarlyView.We successfully constructed CAST/EiJ mice models infected with low‐dose vaccinia virus (VACV‐L), high‐dose VACV (VACV‐H), and mpox virus (MPXV), demonstrating that VACV‐L and MPXV infections induced splenomegaly in mice, and VACV‐H infection caused mortality in mice.

Applications in Plant Sciences, EarlyView.Abstract Premise This study capitalized on a library of single‐nucleotide polymorphisms created via whole genome sequencing (WGS) to develop and test a PCR assay for detecting toxic Digitalis species in food products. Complex foods can be difficult to analyze, but safeguarding consumer well‐being and public health necessitates that products regulated ...

A new genus, Desertispora, and a new species, Diversispora sabulosa, in the family Diversisporaceae (order Diversisporales, subphylum Glomeromycotina) [PDF]
, 2018 Phylogenetic analyses of sequences of the SSU-ITS-LSU nrDNA segment and the RPB1 gene showed that the arbuscular mycorrhizal fungus originally described as Diversispora omaniana does not belong to the genus Diversispora, but represents a separate clade ...

Applications in Plant Sciences, EarlyView.Abstract Premise Current phylogenies of Amaranthaceae sensu stricto (s.s.) are inadequately sampled and resolved to reflect the entire evolutionary history of the lineage, which is likely complex due to at least three whole‐genome duplication events, occasionally followed by subsequent additional polyploidization events and rapid diversification of ...
