Ostermeier et al. introduce AncM, a new factor for structuring the photosynthetic membrane system in cyanobacteria. Plant Cell https://doi.org/10.1093/plcell/koab253 By Matthias Ostermeier, Steffen Heinz and Jörg Nickelsen at Molecular Plant Science at LMU Munich Background: Cyanobacteria are photosynthetic bacteria and a sister group to chloroplasts, which are the site of photosynthesis in green algae and […]
Feng Zhu and colleagues investigate the time-resolved mGWAS of dark-induced senescence. https://doi.org/10.1093/plcell/koab251 By Feng Zhu and Alisdair R. Fernie Background: In cellular circumstances under which nutrients are scarce, plants must degrade polymers to recycle carbon (C) and nitrogen (N) sources for use in their sink tissues. Dark-induced senescence is one such circumstance. During dark-induced senescence, […]
Lee et al. unravel a mitochondrial transporter responsible for selectively exporting citrate in exchange for malate. Plant Cell (2021) By Chun Pong Leea, Marlene Elsässerb, Philippe Fuchsb,c, Ricarda Fenskea, Markus Schwarzländerb, A. Harvey Millara aARC Centre of Excellence in Plant Energy Biology, Bayliss Building M316, University of Western Australia, 35 Stirling Highway, Crawley 6009, Western […]
Ye et al. investigate H+ tolerance mechanisms in Arabidopsis The Plant Cell (2021) Plant Cell https://doi.org/10.1093/plcell/koab226 By Jia Yuan Ye and Chong Wei Jin Background: Acid soils cover nearly half of the world’s arable lands. Application of urea-N and ammonium-N fertilizers markedly increases soil acidification due to proton (H+) generation from nitrification. High H+ concentrations […]
Ballester et al. reveal how stigma development in Arabidopsis requires the formation of different higher-order transcription factor complexes of increasing complexity. https://doi.org/10.1093/plcell/koab236 By Cristina Ferrándiz Instituto de Biología Molecular y Celular de Plantas, CSIC-UPV Background: The stigma is a specialized tissue that forms at the top of the pistil, the female organ of the flower. […]
Wang and colleagues investigated the starvation response of rice seedlings. By Wentao Wang and Yue Lu Background: For survival and growth, cells of all living organisms must balance their energy consumption and supply. Although energetically autonomous (through photosynthesis), plants are continuously challenged by their changing environment and especially by diverse stresses that affect plant physiology […]
Ma et al. investigate a VDAL protein from Verticillium dahliae that can enhance plant disease. Plant Cell https://doi.org/10.1093/plcell/koab221 By Aifang Ma, Zhizhong Gong and Junsheng Qi Background: Verticillium wilt, also called a plant cancer disease, causes massive losses in multiple crops including cotton. Increasing the plant resistance to Verticillium wilt is a critical challenge worldwide. […]
Incarbone et al. use an epitope-tagged protein that binds double-stranded RNAs to fish out viral replication complexes and identify the associated proteins. Plant Cell. https://doi.org/10.1093/plcell/koab214 Marco Incarbone (GMI, Vienna) and Christophe Ritzenthaler (IBMP, Strasbourg) Background: Viruses can cause devastating diseases in plants, and understanding their molecular workings is of great importance. All RNA viruses, which […]
Li et al. reveal how the cryptochrome CRY2 regulates freezing tolerance in Arabidopsis. https://doi.org/10.1093/plcell/koab215 By Youping Li Background: Cold acclimation via exposure to non-lethal low temperatures enhances frost resistance in plants. This process requires light; however, we know very little about the underlying mechanism. The red light photoreceptor phyB functions as a thermosensor to perceive […]
