How is this possible? The explanation came from one of the 20th century’s great discoveries in plant science: detection of the elusive pigment phytochrome, whose action determines how plants are able ...

They interact with other proteins such as phytochrome-interacting factors (PIFs), which trigger physiological responses to the stimuli, such as growth. Phytochromes react to red light: in the dark ...

Plants 'see' this through the light-sensitive pigment phytochrome," says Ronald Pierik, professor of molecular biology at Wageningen University & Research. The pigment is like a switch ...
