PPS — Pisum sativum

Summary

PSAT7G136560 (PPS, also known as MAX2) encodes an F-box and leucine-rich repeat-containing protein with transcription regulator activity and DNA-binding activity. This garden pea gene is associated with strigolactone and karrikin signaling pathways, including response to strigolactone and karrikin, strigolactone anabolism, and SCF complex assembly. It is linked to bud dilation, shoot morphogenesis, de-etiolation, and cuticle development. The encoded protein localizes to the nucleus, cytoplasm, SCF complex, and mitochondria. PPS is associated with numerous traits including shoot branching, axillary bud morphology, stem elongation, petiole shape, floral organ number, anther morphology, seed dormancy, root hair elongation, lateral root number, and carotenoid content. Studies of related genes in other species link the family to strigolactone perception, shoot branching, root skewing, drought resistance, and pathogen resistance.
