Phytochrome B (phyB) is a photorreceptor that senses changes in red (R) to far-red (FR) ratio (R:FR) of sunlight. Low R:FR values perceived by phyB indicate the proximity of neighboring plants, and trigger a suit of adapatative morpholigial responses collectively known as shade avoidance syndrome (SAS). Recent work indicates that phyB is also a modulator of plant defenses agains insects and pathogens.
