Glycosylceramide assembly and function in a model bryophyte

This study investigates glycosylceramide assembly and function in the moss Physcomitrium patens by generating and analyzing mutants with defects in sphingolipid desaturation and glycosylceramide synthesis.

Old Yellow Enzyme from Brevibacillus nitrificans functions as 12-oxo-phytodienoic acid reductase in planta

The paper identifies BnOPR from Brevibacillus nitrificans as a functional OPDA reductase that rescues the male infertile phenotype in Arabidopsis thaliana.

Complex sphingolipids are essential for cell division and plasmodesmal development in the moss Physcomitrium patens

This study identifies the role of complex sphingolipids in cell division and plasmodesmal development in the moss Physcomitrium patens through mutant analysis.

Setaphyte VERY-LONG-CHAIN FATTY ACYL DESATURASES are desaturases that impact glycerolipid and sphingolipid metabolism

The paper characterizes SFDs in setaphytes, showing they desaturate VLCFAs in sphingolipids and glycerolipids, likely via acyl-CoA substrates, and suggests renaming them VFADs.

Wax ester synthase overexpression affects stomatal development, water consumption and growth of poplars

This study overexpresses wax ester synthase in poplars to improve cuticular properties, resulting in reduced stomatal conductance, increased water-use efficiency, and a growth trade-off after prolonged drought.

Identification of INOSITOL PHOSPHORYLCERAMIDE SYNTHASE 2 (IPCS2) as a new rate-limiting component in Arabidopsis pathogen entry control

This study identifies IPCS2 as a key enzyme in sphingolipid biosynthesis that regulates polar secretion of PEN3 to block fungal entry in Arabidopsis.

Time-resolved oxidative signal convergence across the algae-embryophyte divide

The paper studies stress response kinetics in early land plants and their algal relatives using multi-omics data to infer ancient gene regulatory networks.

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.

The GPAT4/6/8 clade functions in Arabidopsis root suberization non-redundantly with the GPAT5/7 clade required for suberin lamellae

This paper shows that GPAT4/6/8 and GPAT5/7 clades in Arabidopsis have non-redundant roles in root suberization, with GPAT5/7 specifically required for lamellated suberin structure.

RfaA (YqhY), a novel adaptor protein, controls metabolite-sensitive protein degradation in Bacillus subtilis

This paper identifies RfaA as a regulator of fatty acid synthesis in Bacillus subtilis that targets AccC for degradation in the absence of glutamate, preventing fatty acid toxicity.

Dual action of sphinganine in the plant disease resistance to bacteria.

This study shows that sphinganine suppresses the hypersensitive response in Arabidopsis by disrupting plasma membrane organization and effector function during bacterial infection.
