Stressful 'memories' of plants: evidence and possible mechanisms
TLDR
The term “stress imprint” is used in this review to describe this plant-based phenomenon because sustained alterations in levels of key signalling metabolites or transcription factors could provide an explanation for how plant metabolism is altered by exposure to various stresses.About:

Molecular aspects of defence priming
TL;DR: Recent progress made in unravelling molecular aspects of defence priming that is the accumulation of dormant mitogen-activated protein kinases, chromatin modifications and alterations of primary metabolism are summarized.
Journal ArticleDOI
Priming for Enhanced Defense
TL;DR: This review covers recent advances in disclosing molecular mechanisms of priming, which include elevated levels of pattern-recognition receptors and dormant signaling enzymes, transcription factor HsfB1 activity, and alterations in chromatin state.

Long-distance signalling in plant defence
Martin Heil,Jurriaan Ton +1 more
TL;DR: This work compares the advantages and constraints of vascular and airborne signals for the plant, and discusses how they can act in synergy to achieve optimised resistance in distal plant parts.
Journal ArticleDOI
Next-Generation Systemic Acquired Resistance
TL;DR: The results suggest that transgenerational SAR is transmitted by hypomethylated genes that direct priming of SA-dependent defenses in the following generations, indicating an epigenetic basis of the phenomenon.
Journal ArticleDOI
Defense Priming: An Adaptive Part of Induced Resistance.
TL;DR: Priming is an adaptive strategy that improves the defensive capacity of plants and can be durable and maintained throughout the plant's life cycle and can even be transmitted to subsequent generations, therefore representing a type of plant immunological memory.

The complex language of chromatin regulation during transcription
TL;DR: This work has shown that transcription occurs against a backdrop of mixtures of complex modifications, which probably have several roles, and suggests that a more likely model is of a sophisticated, nuanced chromatin 'language' in which different combinations of basic building blocks yield dynamic functional outcomes.

Transcriptional regulatory networks in cellular responses and tolerance to dehydration and cold stresses.
TL;DR: This review article highlights transcriptional regulation of gene expression in response to drought and cold stresses, with particular emphasis on the role of transcription factors and cis-acting elements in stress-inducible promoters.
Journal ArticleDOI
Perceptions of epigenetics
TL;DR: During the past year, more than 2,500 articles, numerous scientific meetings and a new journal were devoted to the subject of epigenetics, portrayed by the popular press as a revolutionary new science — an antidote to the idea that the authors are hard-wired by their genes.

The molecular basis of dehydration tolerance in plants
J. Ingram,Dorothea Bartels +1 more
TL;DR: A large number of genes with a potential role in drought tolerance have been described, and major themes in the molecular response have been established.

Active genes are tri-methylated at K4 of histone H3
Helena Santos-Rosa,Robert Schneider,Andrew J. Bannister,Julia A. Sherriff,Bradley E. Bernstein,N. C. Tolga Emre,Stuart L. Schreiber,Jane Mellor,Tony Kouzarides +8 more
TL;DR: It is shown that the Saccharomyces cerevisiae Set1 protein can catalyse di- and tri-methylation of K4 and stimulate the activity of many genes, establishing the concept of methyl status as a determinant for gene activity and extending considerably the complexity of histone modifications.
