Abstract
Deacetylation Ensures Timely Regulation of Flowering
Highlights
If a plant flowers too late in the season, the cold temperatures will prevent fruit from ripening
As to how plants regulate such competing signals, research points to a histone deacetylation pathway that dampens the expression of a molecule thought to control flowering
These findings, published in the August issue of PLOS Biology, identify a new protein that is integral to the plant histone deacetylase complex
Summary
If a plant flowers too late in the season, the cold temperatures will prevent fruit from ripening. This is in part why plants use complex regulatory pathways to interpret environmental signals that determine when they flower. Some plants bloom after exposure to longer periods of daylight, but this can trigger the regulatory pathways thought to repress precocious flowering.
