In Posidonia oceanica cadmium induces changes in DNA methylation and chromatin patterning
TL;DR: The data demonstrate that Cd perturbs the DNA methylation status through the involvement of a specific methyltransferase, linked to nuclear chromatin reconfiguration likely to establish a new balance of expressed/repressed chromatin.

Protein degradation - an alternative respiratory substrate for stressed plants
Wagner L. Araújo,Takayuki Tohge,Kimitsune Ishizaki,Kimitsune Ishizaki,Christopher J. Leaver,Alisdair R. Fernie +5 more
TL;DR: This work reviews events with particular reference to amino acid catabolism and its role in supporting the tricarboxylic acid cycle and direct electron supply to the ubiquinone pool of the mitochondrial electron transport chain in plants.

The stay-green trait
Howard Thomas,Helen J. Ougham +1 more
TL;DR: The onset and progress of senescence are phenological metrics that show climate change sensitivity, indicating that understanding stay-green can contribute to the design of appropriate crop types for future environments.

TL;DR: Comparison of the N-replete versus N-deplete proteome indicated that abundant proteins with a high N content are reduced in N-starved cells, while the proteins that are increased have lower than average N contents, suggesting an approach for engineering increased N-use efficiency.

Five ways to stay green.
Howard Thomas,Catherine Howarth +1 more
TL;DR: The relationship between carbon income and expenditure over the life of a leaf is described and related to the productivity benefits of altering the timing of senescence initiation, and the question of the limits on stay-green as a productivity-enhancing character is addressed.
Journal ArticleDOI
Chlorophyll degradation during senescence
TL;DR: Chl breakdown is a prerequisite to detoxify the potentially phototoxic pigment within the vacuoles in order to permit the remobilization of nitrogen from Chl-binding proteins to proceed during senescence.

Programmed cell death in plants : a pathogen-triggered response activated coordinately with multiple defense functions
Jean T. Greenberg,Allan Guo,Daniel F. Klessig,Daniel F. Klessig,Frederick M. Ausubel,Frederick M. Ausubel +5 more
TL;DR: In this paper, the authors describe mutant A. thaliana plants that contain lesions in a single accelerated cell death (ACD) gene called ACD2 and that bypass the need for pathogen exposure to induce the hypersensitive response (HR) to pathogens.
