Hou et al. explore the role of the HOPS/CORVET complex in plant reproduction Saiying Hou, Sheng Zhong and Li-Jia Qu State Key Laboratory for Protein and Plant Gene Research, Peking-Tsinghua Center for Life Sciences at College of Life Sciences, Peking University, Beijing 100871, People’s Republic of China Background: In flowering plants, two sperm cells are […]
Nonis et al. explore the circular permutation of the common sugar-binding protein ConA https://doi.org/10.1093/plcell/koab130 by Samuel Nonis and Joshua Mylne* (The University of Western Australia; *,current address, Curtin University) Background: Jack bean concanavalin A (conA) is a sugar-binding protein with a long and proud history. Discovered over a century ago, conA was one of the […]
Stuart et al. identify the barley Viridis-k gene and assign a specific function for a C-type ferredoxin as the long-sought electron donor for the cyclase enzyme in chlorophyll biosynthesis. https://doi.org/10.1093/plcell/koab150 Background: Chlorophyll is the green color of plants. It is made in several consecutive steps each catalyzed by an enzyme. Mutants from photosynthetic organisms have […]
Pedroza-Garcia report that the necessity for DNA damage response kinases under non-stress conditions is higher in maize than in Arabidopsis, indicating that the mechanisms maintaining genome integrity may be more important for vegetative and reproductive development than previously thought. Plant Cell https://doi.org/10.1093/plcell/koab158 By José Antonio Pedroza-Garciaa,b and Lieven De Veyldera,b aDepartment of Plant Biotechnology and Bioinformatics, […]
Zupok et al. demonstrate that photosynthesis genes encoded on the chloroplast genome can establish hybridization barriers. Plant Cell. (2021) https://doi.org/10.1093/plcell/koab155 By Arkadiusz Zupok, Danijela Kozul and Stephan Greiner, Max Planck Institute of Molecular Plant Physiology, Potsdam/Golm, Germany Background: Hybrid incompatibility between the cytoplasm (the genomes of chloroplasts and mitochondria) and the nucleus is considered a […]
Furuya et al. identify BEH3 as a stabilizer in the cambium in Arabidopsis thaliana By Tomoyuki Furuyaa,b and Yuki Kondoa,b. a Graduate School of Science, Kobe University, Japan b Graduate School of Science, The University of Tokyo, Japan. Background: Just like trees, plants like Arabidopsis undergo continuous radial growth from the activity of vascular stem […]
Le et al. demonstrate that mitochondria get pyruvate three different ways. Plant Cell By X.H. Le, C.P. Lee and A.H. Millar The University of Western Australia Perth, Australia Background: Plants photosynthesise and make starch in the day so that at night they can extract energy from starch for plant growth and development. That energy extraction […]
Zhang et al. show that a transcription factor module modulates TCA cycle strength and thus reactive oxygen species homeostasis in rose petals. Plant Cell. https://doi.org/10.1093/plcell/koab152 Background: Reactive oxygen species (ROS) are by-products of several primary metabolic pathways and high levels of ROS accelerate cell death and organ senescence. ROS also serve as signaling molecules and […]
Baile et al. discover how EAR domain-containing transcription factors recruit the polycomb group complex PRC2 to mediate gene repression in Arabidopsis. The Plant Cell (2021) https://doi.org/10.1093/plcell/koab139 By Fernando Baile and Myriam Calonje Institute of Plant Biochemistry and Photosynthesis (IBVF-CSIC-US), Avenida Américo Vespucio 49, 41092, Seville, Spain. Background: In eukaryotes, the fundamental packaging subunit of chromatin […]
