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.

Degradation of Fatty Acid Export Protein1 by Rhomboid-Like Protease11 Contributes to Cold Tolerance in Arabidopsis

The paper shows that RBL11-mediated degradation of FAX1 is critical for cold tolerance in Arabidopsis.

Seed Longevity is Controlled by Metacaspases

The paper identifies metacaspases as regulators of seed longevity by modulating CDC48 activity through proteolytic control of its adaptor PUX.

Phase Separation of a Nodulin Sec14-like protein Maintains Auxin Efflux Carrier Polarity at Arabidopsis Plasma Membranes

The paper shows that phase separation of SEC14-like protein, mediated by proteolysis, maintains auxin efflux carrier polarity at Arabidopsis plasma membranes, contributing to root developmental robustness.

Palmitvaccenic acid (Δ11-cis-hexadecenoic acid) is synthesized by an OLE1-like desaturase in the arbuscular mycorrhiza fungus Rhizophagus irregularis

The paper identifies and characterizes RiOLE1-LIKE, a desaturase in Rhizophagus irregularis responsible for synthesizing palmitvaccenic acid, and shows its conservation in AM fungi.

Inhibition of acetyl-CoA carboxylase by spirotetramat causes lipid depletion and surface coat deficiency in nematodes

This study shows that spirotetramat inhibits nematode acetyl-CoA carboxylase, causing lipid depletion and surface coat deficiency, suggesting a new nematicidal mechanism.

Lipid transfer from plants to arbuscular mycorrhiza fungi

The paper identifies plant lipid transfer to arbuscular mycorrhiza fungi, showing that fungal growth depends on lipid, not just sugar, from the host.
