Chimeric Activators and Repressors Define HY5 Activity
Research, The Plant Cell, The Plant Cell: In BriefEarly during seedling development and throughout their lives, plants sense and adapt to their constantly changing environment. Germinated seedlings perceive light which triggers a major developmental switch ultimately leading to photoautotrophic growth. This complex process, referred to broadly as photomorphogenesis,…
Plant Pathogens Recruit PI(4,5)P2 to the Interfacial Membrane for Disease Development
Blog, Research, The Plant Cell, The Plant Cell: In a NutshellQin et al. show that PI(4,5)P2 functions as a susceptibility factor for plant disease. Plant Cell https://doi.org/10.1105/tpc.19.00970
By Li Qin and Yangdou Wei. Department of Biology, University of Saskatchewan, Canada
Background: Biotrophic plant pathogens such as powdery mildews and rusts require…
Security Notice: This Plant Immunity is under mRNA Surveillance
Research, The Plant Cell, The Plant Cell: In BriefEvery manufacture relies on a quality control process to ensure that the released product is without defects. Similarly, each transcript leaving the eukaryotic nucleus is subjected to mRNA surveillance, which helps to ensure that only flawless mRNAs are directed to translation. For example, transcripts…
Pollen surface replenished: a tapetal flavonoid transporter
Research, The Plant Cell, The Plant Cell: In a NutshellGrunewald et al. identify a flavonoid transporter required for the deposition of flavonol-b-1,2-linked diglycosides to the outer pollen wall in Arabidopsis thaliana. The Plant Cell (2020) https://doi.org/10.1105/tpc.19.00801

A Roadmap Toward Large-Scale Genome Editing in Crops
Research, The Plant Cell, The Plant Cell: In BriefIf the planet does not turn to ash before 2050, farmers will need to produce twice as much on roughly the same available arable land to feed the ever-growing world population. But since the Green Revolution of the 1950s and 1960s, progress in crop yield has been incremental. And for good reason: most…
Tools to unravel the mystery of why some tomatoes are hairier than others
Research, The Plant Cell, The Plant Cell: In a NutshellGaldon-Armero et al. present an image resource that can be used to identify natural variation in leaf epidermal development in tomato. The Plant Cell (2020). https://doi.org/10.1105/tpc.20.00127
By Javier Galdon-Armero and Cathie Martin, John Innes Centre, Norwich, UK
Background: Just like our…
Twin-Positive Motifs Function as Specific Plastid Targeting Signals
Research, The Plant Cell, The Plant Cell: In BriefPrecise trafficking of proteins to their proper destinations in the cell, whether to an organelle, a membrane, or the cytoplasm, is required for optimal cellular function. Because most plastid proteins are nucleus-encoded and translated in the cytoplasm, proper targeting and import relies on the presence…
Exosome-Deficient Mutants Reveal Rare Promoter Upstream Transcripts (PROMPTs) in Arabidopsis
Research, The Plant Cell, The Plant Cell: In BriefIn eukaryotes and archaea, protein-coding DNA is transcribed to messenger RNA (mRNA) via a preinitiation complex (PIC) composed of over 100 proteins, among them regulatory proteins, numerous transcription factors, and RNA polymerase II—the enzyme that produces precursor messenger RNA (pre-mRNA). Although…
