This study shows ppGpp signaling in Arabidopsis thaliana modulates immune outcomes by controlling defense gene expression, rather than just scaling immune response magnitude.

The paper shows alternative splicing generates regulatory lncRNAs from protein-coding genes in Arabidopsis, forming autoregulatory RNA-protein feedback loops under dark conditions.

The paper introduces a simple, rapid, and cost-effective subcellular fractionation protocol for isolating nuclear and cytoplasmic components from plant tissues without protoplastization.

This study identifies At-RS31 as a plant-specific splicing factor that regulates alternative splicing and integrates TOR and ABA signaling pathways through its binding targets and interactions with other splicing factors.

The paper investigates how light regulates alternative polyadenylation (APA) in Arabidopsis thaliana, finding that light affects APA in 30% of genes and involves chloroplasts and mitochondrial activity.

The paper shows that sugars act as mobile signals controlling alternative splicing in roots through the TOR kinase pathway, with mitochondria playing a key role in this process.
