The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.

The maize CLAVATA receptor, FEA2, functions in the perception of two different ligands, and remarkably that signaling from these different inputs is differentiated by the receptor interacting with two different downstream components.

Phosphate accumulation in zinc-deficient Arabidobsis shoots is regulated by a pathway involving the transcription factor bZIP23, the phospholipid-remodelling enzyme LPCAT1 and the transporter PHT1;1.

Stromules induced during plant innate immunity dynamically interact and use the cytoskeleton to form and to direct the movement of chloroplasts.

Flowers of different plant species show distinct and highly diverse patterns of temperature across their surfaces, and bumblebees are able to differentiate between these previously unnoticed but widespread floral cues.

Bumblebees use invisible temperature patterns on flowers to make foraging decisions.

Young defense metabolites are often believed to be solely outputs but evidence suggests that they can regulate ancient signaling pathways.

Nucleosomes and linker histones block eukaryotic cytosine methylation.

The horizontal acquisition of virulence plasmids is potentiated by production practices in plant nurseries and is sufficient to transition Rhodococcus from being beneficial to being pathogenic.

The acquisition of a virulence plasmid is sufficient to turn a beneficial strain of Rhodococcus bacteria into a pathogen.
