"Thermometer" protein regulates blooming

Caption

Left: Evening Complex (EC) attached to DNA. Right: LUX protein bound to DNA double helix. EC acts like a temperature sensor. At low temperatures, it prevents the expression of growth genes by binding to the DNA. When temperatures are high enough, it separates from the DNA, permitting gene expression and subsequent plant flowering.
