ASTREL Projection: Comparative Phylogenomics Uncovers Novel Genes Co-eliminated with the EDS1 Immune Pathway

The 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…

Shooting for the STARRs: A Modified STARR-seq Assay for Rapid Identification and Evaluation of Plant Regulatory Sequences in Tobacco Leaves

A 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.…

Remodeling Chromatin in an ARID Environment

The 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

Membrane 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…

Endosidin20: A Key to Unlock the Secrets of Cellulose Biosynthesis

By now, you would think we’d know everything about cellulose, given its status as the most abundant biopolymer on Earth and its simple chemical composition. Cellulose is composed of β-1,4-D-glucose units assembled into straight chain polymers. These rod-like molecules are packed into strong microfibrils…

Breaking the Mold: Reduced Protein Storage in Brassica napus Seed Triggers Unexpected Structural Changes

During development, seeds pack away large amounts of storage nutrients in the form of starch, proteins, and lipids (typically triacylglycerides), but the ratios of these storage products vary tremendously between seed types. Because of the obvious agricultural implications, researchers have long sought…

Sugar Is Sweeter: Plants Open Their “Mouths” for Glucose, Not Malate, In the Morning

Regulation of stomatal opening and closing in plants in response to environmental cues continues to be well studied (García-León et al., 2019; Li et al., 2020), as it is important for balancing the intake of carbon dioxide for photosynthesis (PS) with the release of water during transpiration. But…

MYB30 Regulates Photomorphogenesis via Interactions with Active Phytochromes and PIFs

MYB proteins are a group of transcription factors that are highly conserved in all vertebrates and were first implicated in avian myeloblastosis (leukemia). Subsequently, they were shown to be cellular proto-oncogenes that regulate production of blood cells in animals. MYB proteins contain a DNA-binding…

The Butterfly Effect: Natural Variation of a Chloroplast tRNA-Modifying Enzyme Leads to Pleiotropic Developmental Defects in Rice

Translation of RNA information into protein is a fundamental process ensuring the production of functional proteins in cells. Transfer RNA (tRNA) is a vital component of the translation machinery as it delivers the correct amino acids to the elongating peptide chain based on codon-anticodon recognition.…
