Wang et al. identify signals related to induced systemic resistance produced by a root-colonizing fungus. Plant Cell https://doi.org/10.1105/tpc.19.00487 Background: Trichoderma virens is an agriculturally-relevant root-colonizing fungus that provides its plant hosts many benefits, such as increased growth, destruction of soil-borne pathogens, and enhanced systemic resistance against foliar pathogens, termed induced systemic resistance (ISR). The mobile ISR signals […]
Paul, Saha, et.al investigated the Improvement of nitrogen nutrition in rice by interaction with the basidiomycete Rhodotorula mucilaginosa and its N2-fixing endobacteria. Plant Cell https://doi.org/10.1105/tpc.19.00385 By Karnelia Paul1, Chinmay Saha1,2,3 and Anindita Seal1 1Department of Biotechnology and Dr. B. C. Guha Centre for Genetic Engineering and Biotechnology, University of Calcutta, 35 Ballygunge Circular Road, Kolkata […]
Zhuo et al. show the existence of jasmonate-activated MYC2-Dof2.1-MYC2 transcriptional loop that is involved in the promotion of leaf senescence in Arabidopsis. Plant Cell https://doi.org/10.1105/tpc.19.00297 By M. Zhuo, Y. Sakuraba, and S. Yanagisawa, The University of Tokyo, Japan Background: Dof (DNA-binding with one finger) proteins are plant-specific transcription factors associated with a variety of physiological […]
Sun et al. reveal the subcellular organization of photosystem biogenesis in Chlamydomonas. Plant Cell https://doi.org/10.1105/tpc.19.00263 by Melissa Valente-Paterno, Yi Sun and William Zerges. Department of Biology, Concordia University. Background: Cells localize intracellular processes to subcellular organelles in order to enhance their efficiency. For example, in plant and algal cells, chloroplasts carry out photosynthesis. Within chloroplasts, […]
For the past two decades, glyphosate has been the most used herbicide worldwide, resulting in prolonged, extreme selection pressure for glyphosate-resistant (GR) weeds. Glyphosate’s only target as a herbicide is 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), an enzyme of the shikimate pathway. It forms a stabile dead-end complex by binding EPSP to form a transition-state analogue that is […]
Baetsen-Young et al. identified key transcriptomic differences in coexpression networks following Fusarium virguliforme infection of symptomatic (soybean) vs. asymptomatic (corn) hosts Plant Cell https://doi.org/10.1105/tpc.19.00697 By Amy Baetsen-Young and Brad Day, Michigan State University Background: Fungal plant pathogens elicit an array of symptoms during host colonization, and in total, these include changes in host plant development, […]
Huang et al. found that SA inhibits hook formation and is dependent on the ET pathway in Arabidopsis. Plant Cell https://doi.org/10.1105/tpc. 19.00658 By Peixin Huang, Yichuan Wang, and Hongwei Guo Background: For germnating seedlings to survive and become a mature plant, they must push through the overlaid soil to reach the light. During this process, […]
O’Leary et al. show that the TOR signalling pathway in plants responds to amino acid levels by eliciting regulatory effects on respiratory energy metabolism at night, uniting a hallmark mechanism of TOR regulation across eukaryotes. Plant Cell https://doi.org/10.1105/tpc.19.00157 By Brendan O’Leary and Harvey Millar Background: Plant leaves have two main energy-generating metabolic systems, photosynthesis and […]
