Plant immunity can be induced by pathogen signals or environmental cues. Here, the authors show that plant leaves use trichomes to sense incoming raindrops and trigger basal defence responses to protect against subsequent microbial infection.

Dynamic ubiquitination determines transcriptional activity of the plant immune coactivator NPR1

Autor: Michael J Skelly, James J Furniss, Heather Grey, Ka-Wing Wong, Steven H Spoel

Publikováno v: eLife, Vol 8 (2019)

Activation of systemic acquired resistance in plants is associated with transcriptome reprogramming induced by the unstable coactivator NPR1. Immune-induced ubiquitination and proteasomal degradation of NPR1 are thought to facilitate continuous deliv

Post-translational modification of proteins by ubiquitin is an essential cellular signaling mechanism in all eukaryotes. Ubiquitin is removed from target proteins by a wide range of deubiquitinase (DUB) enzymes with different activities and substrate

Plants form calluses and regenerate new organs when incubated on phytohormone-containing media. While accumulating evidence suggests that these regenerative processes are governed by transcriptional networks orchestrating wound response and developme

Transcription factors (TFs) are important regulators of plant growth and development and responses to stresses. TFs themselves are also prone to multiple posttranslational modifications (PTMs). However, redox-mediated PTM of TFs in plants remains poo
