The α/β-hydrolases KAI2 and D14 are paralogous receptors for karrikins and strigolactones, two classes of plant growth regulators with butenolide moieties. KAI2 and D14 act in parallel signaling pathways that share a requirement for the F-box protein MAX2, but produce distinct growth responses by regulating different members of the SMAX1-LIKE/D53 family.(More)
A set of PpKAI2 - LIKE paralogs that may encode strigolactone receptors in Physcomitrella patens were identified through evolutionary, structural, and transcriptional analyses, suggesting that strigolactone perception may have evolved independently in basal land plants in a similar manner as spermatophytes. Carotenoid-derived compounds known as(More)
