Plasticity of the Arabidopsis leaf lipidome and proteome in response to pathogen infection and heat stress

Biotic and heat stress strongly alter the lipidome and proteome of Arabidopsis leaves, including lipid droplet proteome composition.

Environmental gradients reveal stress hubs predating plant terrestrialization

The paper uses RNAseq and photophysiological data from Mesotaenium under environmental stress to identify stress response hubs in algae, suggesting ancient molecular programs predating plant terrestrialization.

SLDP and LIPA mediate lipid droplet-plasma membrane tethering in Arabidopsis thaliana

SLDP1, SLDP2, and LIPA tether lipid droplets to the plasma membrane in Arabidopsis thaliana seedlings.

ultraID: a compact and efficient enzyme for proximity-dependent biotinylation in living cells

The paper introduces ultraID, a compact and efficient biotin ligase for proximity-dependent biotinylation, demonstrating its use in probing interactomes with high temporal resolution.

Multi-omics analysis of xylem sap uncovers dynamic modulation of poplar defenses by ammonium and nitrate

This study analyzes how nitrogen supply affects xylem sap composition, endophyte growth, and leaf defenses in poplar through multi-omics approaches.

Hülle-cell-mediated protection of fungal reproductive and overwintering structures against fungivorous animals

The paper shows Hülle cells in Aspergillus nidulans produce xanthones that protect reproductive structures from fungivorous animals.

Co-option of a seed-like proteome by oil-rich tubers

The paper identifies a seed-like proteome co-opted in the tubers of yellow nutsedge for desiccation tolerance and lipid storage.
