ASTREL Projection: Comparative Phylogenomics Uncovers Novel Genes Co-eliminated with the EDS1 Immune Pathway
Research, The Plant Cell, The Plant Cell: In BriefThe plant immune system is largely centered around immune receptors that monitor for pathogen-derived signatures. Extracellular immunity is afforded through cell-surface receptors recognizing common microbial motifs like bacterial flagellin or fungal chitin (Boutrot and Zipfel, 2017). By contrast, intracellular…
Cold-responsive Regulatory DNA Landscapes and Regulatory Networks in Grasses

Shooting for the STARRs: A Modified STARR-seq Assay for Rapid Identification and Evaluation of Plant Regulatory Sequences in Tobacco Leaves
Research, The Plant Cell, The Plant Cell: In BriefA single genome gives rise to different cell types and organs in response to precise temporal and spatial regulation of gene expression, driven by developmental and environmental cues. These expression patterns are orchestrated by cis-regulatory elements, distal enhancers and gene-proximal promoters.…
Glutelin mRNAs are transported on endosomes
Research, The Plant Cell, The Plant Cell: In a NutshellTian et al. identify the factors mediating localization of specific mRNAs in developing rice endosperm cells. Plant Cell https://doi.org/10.1105/tpc.20.00111
by Li Tian and Thomas W. Okita
Background: Localization of mRNAs is a universal mechanism to efficiently drive protein targeting in eukaryotes…
Secret Talents: STARCH SYNTHASE 5—Not an Enzyme, but Very Active!
Research, The Plant Cell, The Plant Cell: In a NutshellAbt et al. found that Arabidopsis SS5, a protein homologous to typical starch-synthesizing enzymes, is itself enzymatically inactive, but rather has an important role in the starch granule initiation process.

Remodeling Chromatin in an ARID Environment
Research, The Plant Cell, The Plant Cell: In BriefThe control of gene expression is of fundamental importance for cellular life. In Eukaryotes, linear DNA is wrapped around nucleosomes that constitute a physical barrier to active transcription. Chromatin remodeling complexes modulate the composition, stability and positioning of nucleosomes therefore…

It’s a TRAPP! Arabidopsis Transport Protein Particle (TRAPP) Complexes Contain a Novel Plant-Specific Subunit
Research, The Plant Cell, The Plant Cell: In BriefMembrane vesicle trafficking is the process of moving and distributing signaling molecules from their place of synthesis or capture to target locations inside or outside the cell. Vesicles, mobile membrane compartments produced from the endoplasmic reticulum, carry proteins and other molecules to an…
