DORMANCY REGULATION. "We are also catching first glimpses of the complex web of hormonal and gene expression regulatory pathways controlling seed dormancy as well as the intricate interplay of light-dependent signals such as phytochrome modification, circadian rhythms and phytormonones implicated in light-controlled developmental regulation." http://www.tandfonline.com/doi/full/10.4161/psb.4.5.8276#abstract View in LinkedIn

TARGET GENE. "The “memory of winter” involved in seasonally dependent acquisition of flowering competence (vernalization) has been traced down to complex epigenetic regulation of the gene encoding a specific transcription factor (FLC) in Arabidopsis. Surprisingly, the target genes appear to be different in grasses, albeit the topology of the whole regulatory network may be analogous." http://www.tandfonline.com/doi/full/10.4161/psb.4.5.8276#abstract View in LinkedIn

WHOLE PLANT MEMORY. "Namely, developmental decisions, such as vernalization, flowering induction, photomorphogenesis or breaking of seed dormancy depend on long-term integration and evaluation of light or temperature inputs, sometimes recorded and recalled after a time far exceeding the normal duration of the plant's life cycle. For example, Stellaria seeds can recall whether they have been imbibed in darkness or in light even after more than a year. Further examples of similar long-term “data collection”.” http://www.tandfonline.com/doi/full/10.4161/psb.4.5.8276#abstract View in LinkedIn

TWO STEP. "Moreover, the adjustment of enzyme levels includes a two-step reaction—a change in day length results first in a “half-way” transcriptional response that is followed by adequate translational output only upon repeated or lasting environmental stimulation." http://www.tandfonline.com/doi/full/10.4161/psb.4.5.8276#abstract View in LinkedIn
