EPIGENETICS. "How a single plant genotype can result in a variety of phenotypic outcomes under the same in vitro culture conditions is still far from being completely understood. While underlying mutations in DNA sequence have been pointed out as a likely cause of phenotypic variation, it is also becoming clear that a major role is played by epigenetic regulation." http://jxb.oxfordjournals.org/content/62/11/3713.full View in LinkedIn

DOSE-RESPONSE. "Recognition of individuality can easily be seen from dose‐response curves. Such dose‐response data can vary over three to five orders of magnitude change in the strength of the inducing stimulus, thus indicating the degree of individual variation." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

HYPOTHESIS. "Individuality of the kind commonly observed in plants might be unique. A mechanism for individuality has been proposed as originating from stochastic variation in the distribution between daughter cells of tiny numbers of critical proteins controlling cell and tissue development." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

RESOURCE MOSAIC. "As if to counteract the paucity of different tissues in the normal vegetative plant, continued embryogenic development by meristems results in tissues and cells with enormous varieties of individual behaviour. A reservoir of different cell behaviours becomes available to enable construction of a variety of tissue and plant behaviours to exploit the resource mosaic." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

"INDIVIDUALITY is used to describe situations in which morphologically or anatomically identical cells, tissues or plants show non‐similar responses to signals. Individuality receives little or no investigation in plant science despite being a widespread phenomenon." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

MICRO-RNAs. "By using grafts between wild-type and mutant roots and shoots of Arabidopsis, recent studies have shown that small interfering RNA (siRNA) and microRNA (miRNA) can act as mobile signals that direct epigenetic modifications in the genome of recipient cells." http://jxb.oxfordjournals.org/content/62/11/3713.full View in LinkedIn

EXTRA-EPIGENIC PATHWAY. "Zhang et al., found that H3K27me3 regulates an unexpectedly large number of genes in Arabidopsis (∼4400), suggesting that this is a major silencing mechanism in plants that acts independently of other epigenetic pathways, such as small RNAs (smRNAs) or DNA methylation." http://jxb.oxfordjournals.org/content/62/11/3713.full View in LinkedIn

MARKINGS. "The N-terminal tails of core histone proteins can be covalently modified by acetylation, methylation, phosphorylation, sumoylation, carbonylation, and glycation. The combinatorial set of modifications (histone code) plays an essential role in regulating dynamic changes in chromatin structure, ultimately influencing gene transcription in response to diverse exogenous and endogenous stimuli including stress, pathogen attack, temperature, light, and hormones." http://jxb.oxfordjournals.org/content/62/11/3713.full View in LinkedIn
