ANAC017 Coordinates Organellar Functions and Stress Responses by Reprogramming Retrograde Signaling1[OPEN]
TLDR
RNA sequencing analyses revealed that increased ANAC017 expression leads to higher expression of genes related to mitochondrial stress, cell death/autophagy, and leaf senescence under nonlimiting growth conditions as well as extensive repression of chloroplast function.
Isolation and Respiratory Measurements of Mitochondria from Arabidopsis thaliana.
TLDR
This protocol describes an isolation method of mitochondria from Arabidopsis thaliana leaves using continuous colloidal density gradients and an efficient respiratory measurements of purified plant mitochondria.
Mitochondrial signalling is critical for acclimation and adaptation to flooding in Arabidopsis thaliana.
TLDR
It is revealed that acclimation to submergence is dependent on mitochondrial retrograde signalling and underlying transcriptional re-programming is used as an adaptation mechanism.
Accumulation of endogenous peptides triggers a pathogen stress response in Arabidopsis thaliana.
TLDR
The results indicate that the absence of organellar oligopeptidases PreP1/2 and OOP results in the accumulation of peptides that are perceived as pathogenic effectors and activate the signaling pathways of plant-defense response.

TLDR
DGS1 links mitochondrial protein and lipid import with cellular lipid homeostasis and whole plant stress responses and Whole plant physiology was affected in the dgs1-1 mutant as evidenced by tolerance to imposed drought stress and altered transcriptional responses of markers of mitochondrial retrograde signaling.
Characterization of a novel β-barrel protein (AtOM47) from the mitochondrial outer membrane of Arabidopsis thaliana
Highlight Characterization of a novel β-barrel protein in Arabidopsis identifies its role in leaf senescence by mediating the transport of chloroplast breakdown products across the outer
AtWAKL10, a Cell Wall Associated Receptor-Like Kinase, Negatively Regulates Leaf Senescence in Arabidopsis thaliana
TLDR
Analysis of developmental expression patterns uncovered a putative role of AtWAKL10 in modulating leaf senescence and identified several specific transcriptional alterations, including genes involved in cell extension, cell wall modification, defense response and senescences related WRKYs, which may be implicated in regulatory mechanisms adopted by AtWakl10 in controlling leafsenescence.
