The Butterfly Effect: Natural Variation of a Chloroplast tRNA-Modifying Enzyme Leads to Pleiotropic Developmental Defects in Rice
Research, The Plant Cell, The Plant Cell: In BriefTranslation 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.…
MYB30 Promotes PIF4 and PIF5 Accumulation in the Light
Research, The Plant Cell, The Plant Cell: In a NutshellYan et al. discovered that MYB30, an R2R3-MYB family transcription factor, is a negative regulator of Arabidopsis photomorphogenic development and promotes PIF4 and PIF5 accumulation under prolonged red light irradiation.

Twist of Fate: Ribosomal Stress Reprograms Root Hair Pattering
Research, The Plant Cell, The Plant Cell: In BriefThe root epidermis presents an elegant model to study cell differentiation. Based on positional cues, Arabidopsis distinguishes two epidermal cell types. Cells in the H position, adjacent to the junction of two cortex cells, have the capacity of developing root hair identity, whereas the non-hair cells…
Shaping the Plant Cell Wall: Molecular Characteristics of XOAT1 in Polysaccharide Acetylation
Research, The Plant Cell, The Plant Cell: In BriefPlant cell walls provide mechanical support to plant cells, determine their size and shape, and influence plant development and stress responses. The plant cell wall is composed mainly of polysaccharides, including cellulose, hemicellulose and pectins, with smaller amounts of phenolic polymers and proteins…

Background: Strigolactones (SLs) are carotenoid-derived plant hormones that control many aspects of plant development, such…
Glyphosate Resistance Decoded: the reference sequence of the extrachromosomal DNA Replicon in Amaranth
Research, The Plant Cell, The Plant Cell: In BriefDecades of research in evolutionary genetics has shown that genomic plasticity, in particular variation in gene copy number, is a favored mechanism to provide rapid adaptation to adverse environmental conditions through increase in gene dosage. Gene amplification has been observed across kingdoms and…
XOAT1- At the heart of plant polysaccharide acetylation
Research, The Plant Cell, The Plant Cell: In a NutshellLunin et al. describe a structural and biochemical analysis of the enzyme XOAT1, responsible for the acetylation of the cell wall component xylan, with potential applications in cell wall modification for better biomass valorization.

All Together Now: Phylotranscriptomics Reveals Core Responses to Fungal Infection Across the Pentapetalae
Research, The Plant Cell, The Plant Cell: In BriefOver 450 million years of land plant evolution has led to the acquisition of diverse and often overlapping sets of defense responses that limit pathogen infection. Decades of research has uncovered canonical immune pathways that provide resistance to specialist (hemi)-biotrophic pathogens relying on…
