Arginine methylation of SM-LIKE PROTEIN 4 antagonistically affects alternative splicing during Arabidopsis stress responses Open
Arabidopsis (Arabidopsis thaliana) PROTEIN ARGININE METHYLTRANSFERASE5 (PRMT5) post-translationally modifies RNA-binding proteins by arginine (R) methylation. However, the impact of this modification on the regulation of RNA processing is …

Concerted Transport and Phosphorylation of Diacylglycerol at ER-PM Contacts Sites Regulates Phospholipid Dynamics During Stress Open
A universal response of plants to environmental stresses is the activation of plasma membrane (PM) phospholipase C (PLC) that hydrolyzes phosphatidylinositol phosphate (PIP) to produce soluble inositol phosphate (IP) and diacylglycerol (DA…

<i>SVALKA</i>-POLYCOMB REPRESSIVE COMPLEX2 module controls <i>C-REPEAT BINDING FACTOR3</i> induction during cold acclimation Open
C-REPEAT BINDING FACTORS (CBFs) are highly conserved plant transcription factors that promote cold tolerance. In Arabidopsis (Arabidopsis thaliana), three CBFs (CBF1 to CBF3) play a critical role in cold acclimation, and the expression of …

Antagonistic effects of arginine methylation of LSM4 on alternative splicing during plant stress responses Open
Arabidopsis PROTEIN ARGININE METHYLTRANSFERASE 5 (PRMT5) post-translationally modifies RNA-binding proteins by arginine (R) methylation. The impact of this modification on the regulation of RNA processing is largely unknown. Here we use LS…

Synaptotagmins Maintain Diacylglycerol Homeostasis at Endoplasmic Reticulum-Plasma Membrane Contact Sites during Abiotic Stress Open
SUMMARY Endoplasmic Reticulum-Plasma Membrane contact sites (ER-PM CS) play fundamental roles in all eukaryotic cells. Arabidopsis mutants lacking the ER-PM protein tether synaptotagmin1 (SYT1) exhibit decreased plasma membrane (PM) integr…

Emerging Roles of LSM Complexes in Posttranscriptional Regulation of Plant Response to Abiotic Stress Open
It has long been assumed that the wide reprogramming of gene expression that modulates plant response to unfavorable environmental conditions is mainly controlled at the transcriptional level. A growing body of evidence, however, indicates…

Arabidopsis SME1 Regulates Plant Development and Response to Abiotic Stress by Determining Spliceosome Activity Specificity Open
The control of precursor-messenger RNA (pre-mRNA) splicing is emerging as an important layer of regulation in plant responses to endogenous and external cues. In eukaryotes, pre-mRNA splicing is governed by the activity of a large ribonucl…

Tailoring crop nutrition to fight weeds Open
Increasing crop productivity in an environmental-friendly way is one of the major challenges humankind is facing in the context of food security with a constantly growing population. In this scenario, ensuring adequate levels of soil nutri…

Environment-dependent regulation of spliceosome activity by the LSM2-8 complex in Arabidopsis Open
Spliceosome activity is tightly regulated to ensure adequate splicing in response to internal and external cues. It has been suggested that core components of the spliceosome, such as the snRNPs, would participate in the control of its act…

The LSM1-7 Complex Differentially Regulates Arabidopsis Tolerance to Abiotic Stress Conditions by Promoting Selective mRNA Decapping Open
In eukaryotes, the decapping machinery is highly conserved and plays an essential role in controlling mRNA stability, a key step in the regulation of gene expression. Yet, the role of mRNA decapping in shaping gene expression profiles in r…

The Arabidopsis ethylene overproducer mutant<i>eto1-3</i>displays enhanced freezing tolerance Open
Low temperature is one of the most important environmental stresses constraining plant development and distribution. Plants have evolved complex adaptive mechanisms to face and survive freezing temperatures. Different signaling pathways re…
