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.

Aung et al. reveal that pathogenic bacteria target plant plasmodesmata to colonize and invade surrounding tissues. Plant Cell https://doi.org/10.1105/tpc.19.00707 By Kyaw Aung and Sheng Yang He   Background: Multicellular organisms like animals and plants host a multitude of microorganisms.…

Reddit et al. show that an effector protein from a pathogen modifies a host factor by ADP ribosylation, thereby activating defenses. The Plant Cell https://doi.org/10.1105/tpc.19.00020  Background: To protect themselves against disease, plants employ a family of intracellular receptors called…

Molina-Contreras et al. show how differences in photoreceptors produce the differing shade responses of Arabidopsis and Cardamine. https://doi.org/10.1105/tpc.19.00275  by Sandi PAULIŠIĆ 1 and Jaime F. MARTINEZ-GARCIA 1,2 1, Centre for Research in Agricultural Genomics (CRAG) CSIC-IRTA-UAB-UB. 2,…

Nagashima et al. investigate molecular mechanisms for the sorting of a membrane protein KORRIGAN 1 (KOR1) in plant cells. Plant Cell https://doi.org/10.1105/tpc.19.00714 By Y. Nagashima1, and H. Koiwa1,2 1Vegetable and Fruit Improvement Center and Department of Horticultural Sciences, Texas…

Smit et al. uncover a feed-forward loop that controls vascular development in Arabidopsis. Plant Cell https://doi.org/10.1105/tpc.19.00562 By Margot E. Smit1, Siobhán M. Brady2, and J. Peter Etchells3 1 Stanford University 2 UC Davis 3 Durham University  Background: Vascular tissues…

Descriptive paragraph. Plant Cell https://doi.org/10.1105/tpc.18.00682 By Hui Zhuang and Yunfeng Li Background: The spikelet, often mistaken for a “flower”, is actually an inflorescence unit and can produce one or more florets in some species of grass. This implies that it could be possible…

Beyond its well-known role in muscle contraction, the cytoskeletal component actin participates in many critical cellular processes. Globular actin polymerizes into thin, flexible filaments that assemble into dynamic higher-order structures, such as bundles and networks. In addition to providing mechanical…
