Melainabacteria, a candidate phylum related to Cyanobacteria, has been identified in gut and sediment samples by genomic analysis.

A combination of phylogenetic and biochemical analyses suggest that some unexpected variations in the synthesis of isoprenoids may be widespread across all three domains of life.

A fungal effector secreted by the corn smut pathogen increases the virulence of the pathogen by elevating anthocyanin production and reducing lignification in maize.

A mouse model of atopic dermatitis provides mechanistic evidence for an association between allergic disease and skin cancer.

SAK1, a novel cytoplasmic phosphoprotein, is a key intermediate component of the retrograde signaling pathway controlling nuclear gene expression during acclimation of Chlamydomonas cells to singlet oxygen stress.

Metabolite analysis of plasma from enteric fever patients define signals of organism specific host–pathogen interactions and provides opportunities for new diagnostics.

Pyro-sequencing of two genes involved in bacterial secondary metabolism provides new insights into the rich reservoir of biologically active small molecules found in environmental bacteria.

Research in molecular ecology and evolution is increasingly utilizing the model plant Arabidopsis thaliana, placing a spotlight on its natural history.

Genomic evidence suggests that L-gulonolactone oxidase-the terminal enzyme in vitamin C synthesis, which has been repeatedly lost throughout animal evolution-was lost in plants and other photosynthetic eukaryotes following plastid acquisition.

A chemical biology approach has identified the kinase DYRK1A as a new regulator of the inflammatory response.
