Coatomer complex I is required for the transport of SARS-CoV-2 progeny virions from the endoplasmic reticulum-Golgi intermediate compartment

This study identifies COPI as essential for SARS-CoV-2 virion transport from the ERGIC, showing that COPB2 depletion inhibits viral replication.

Antagonistic Roles of Tau and MAP6 in Regulating Neuronal Development

The paper shows tau and MAP6 have opposing roles in neuronal development by regulating microtubule stability and dynamics in cultured neurons and in vivo.

RudLOV-a new optically synchronized cargo transport method reveals unexpected effect of dynasore

The paper introduces RudLOV, an optical method for synchronized cargo release, revealing dynasore's differential effects on early and late Golgi transport.

Seasonal gene-expression signatures of delayed fertilization in Fagaceae

This study identifies seasonal gene-expression differences between one- and two-year fruiting Fagaceae species, linking delayed fertilization to cold stress and reproductive barrier mechanisms.

SEN1 is responsible for molybdate transport into nodule symbiosomes for nitrogen fixation in Lotus japonicus

The paper identifies SEN1 as a molybdate transporter responsible for exporting molybdate from host plant cytosol to symbiosomes for nitrogen fixation in Lotus japonicus.

Excretion of triacylglycerol as a matrix lipid facilitating apoplastic accumulation of a lipophilic metabolite shikonin.

The paper investigates how plants secrete lipophilic metabolites like shikonin by excreting triacylglycerol as a matrix lipid, facilitating apoplastic accumulation.

Spatial metabolomics using imaging mass spectrometry to identify the localization of asparaptine in Asparagus officinalis

The paper uses spatial metabolomics to locate asparaptine in asparagus spears, showing its accumulation in lateral shoots and validating findings with LC-MS/MS.

Multi-metabolomics using imaging mass spectrometry and liquid chromatography-tandem mass spectrometry for spatially characterizing monoterpene indole alkaloids secreted from roots

The paper uses imaging mass spectrometry and LC-MS/MS to spatially characterize monoterpene indole alkaloids released from plant roots in agar.

The histidine phosphotransfer AHP4 plays a negative role in Arabidopsis plant response to drought

This study shows AHP4 negatively regulates Arabidopsis drought response by modulating gene expression related to stress tolerance mechanisms.

The Arabidopsis NRT1/PTR FAMILY Protein NPF7.3/NRT1.5 is an Indole-3-butyric Acid Transporter Involved in Root Gravitropism

The paper identifies NPF7.3 as an IBA transporter involved in root gravitropism by facilitating IBA uptake, which is necessary for auxin gradient formation.

Three-dimensional reconstructions of the internal structures of haustoria in parasitic Orobanchaceae

Three-dimensional image reconstruction was used to visualize the spatial organization of cell types in the haustoria of parasitic plants with special reference to their interaction with host roots.

GSK3 activity is a cell fate switch that balances the ratio of vascular cell type

The study identifies GSK3 activity as a cell fate switch that regulates the ratio of sieve elements to companion cells in the phloem.

Excessive assimilation of ammonium by plastidic glutamine synthetase is a major cause of ammonium toxicity in Arabidopsis thaliana

This study identifies plastidic glutamine synthetase 2 (GLN2) as the primary cause of ammonium toxicity in Arabidopsis thaliana by inducing shoot acidity.

Lateral organ diversification in plants mediated by the ALOG protein family of transcription factors

The paper identifies MpTAW1, an ALOG family protein in Marchantia polymorpha, as a regulator of lateral organ development and meristem maintenance, showing its conserved function in specifying lateral organ identity across plant lineages.

The RopGEF KARAPPO is Essential for the Initiation of Vegetative Reproduction in Marchantia

This study identifies KARAPPO, a RopGEF, as essential for initiating vegetative reproduction in Marchantia by promoting gemma initial formation through Rop signaling.
