Xylem-mobile Oxylipins are Critical Regulators of Induced Systemic Resistance in Maize

In addition to promoting plant growth and development, the colonization of roots by beneficial microorganisms often provides aboveground tissues with enhanced resistance to pathogen attack. This form of resistance, referred to as ‘induced systemic resistance’ (ISR), relies on the long-distance movement…

Energy vs growth: Plant nutritional decisions are made by TOR

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.

Taking Down Plant Communication Channels to Invade

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.…

THE PLANT CELL Welcomes New Assistant Features Editors

The Plant Cell welcomes 12 new Assistant Features Editors (AFEs) for 2020. They join six continuing AFEs who started in 2019. We would also like to thank all of the original AFEs who stepped down from the editorial board in 2018-2019, who helped us to establish the program and provided valuable input…

AvrRpm1, a 28-year Old Mystery Solved

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…

Personal Trainer: bHLH121 Functions Upstream of a Transcriptional Network of Heavy Lifters Involved in Balancing Iron Levels

Iron is a cofactor of numerous plant proteins that function in processes ranging from redox reactions during photosynthesis to respiration. Typical soils contain approximately 1–5% iron, but much of this iron is not readily accessible to plants due to low solubility. Nongraminaceous plants help solubilize…
