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.

Metabolic analysis of a bacterial synthetic community from maize roots provides new mechanistic insights into microbiome stability

This study investigates the role of metabolites in stabilizing a bacterial synthetic community from maize roots, showing complementary metabolic niches and cross-feeding interactions among strains.

Heat stress leads to rapid lipid remodelling and transcriptional adaptations in Nicotiana tabacum pollen tubes

Nicotiana tabacum pollen tubes adapt to heat stress through metabolomic changes, transcriptional adjustments, and rapid lipid remodelling.

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.

The evolution of the phenylpropanoid pathway entailed pronounced radiations and divergences of enzyme families

This study shows that enzyme families in the phenylpropanoid pathway underwent radiations and divergences in land plants and their algal relatives, suggesting evolutionary versatility in specialized metabolism.

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.

The cell-wall-localised BETA-XYLOSIDASE 4 contributes to immunity of Arabidopsis against Botrytis cinerea

BXL4 is a putative bifunctional xylosidase/arabinofuranosidase localising to the apoplast, important for immunity against the necrotrophic pathogen B. cinerea.
