Models of D14/KAI2 evolution. BP binding pocket. a Traditional model of land plant evolution, with evolution of the D14/KAI2 family superimposed. A single origin of SL perception in the DDK lineage would be sufficient to explain known patterns of SL sensitivity. b ‘Hornworts-basal’ model of land plant evolution, with evolution of the D14/KAI2 family superimposed. Two independent origins of SL perception in the DDK lineage would be required to explain known patterns of SL sensitivity
