MARTIAN ORGANIZATION. "Since a plant can be regenerated from a single meristem, redundancy in tissue development is self‐evident. Furthermore, growth regulators often overlap in their effects. This is organizational plasticity we simply do not understand." http://aob.oxfordjournals.org/content/92/1/1.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

TRANSPOSON CONTROL. "Plants, as well as other highly developed multicellular organisms, show increased DNA methylation when compared with other eukaryotic organisms, probably due to the need for more efficient control of transposons, or the need for additional epigenetic regulation to control the development of many different cell types." http://jxb.oxfordjournals.org/content/62/11/3713.full View in LinkedIn

"PLANT CELL DEDIFFERENTIATION has been mostly studied in protoplast systems. In such experimental systems dedifferentiation can be resolved into acquisition of competence for pluripotentiality and signal-dependent re-entry into S phase, each phase being accompanied by a broad chromatin decondensation. For reactivation of the cell cycle it is usually necessary that plant growth regulators are applied, but this occurs independently from the acquisition of competence for pluripotentiality." http://jxb.oxfordjournals.org/content/62/11/3713.full View in LinkedIn
