PPS — Pisum sativum

Summary

PSAT3G013160 (PPS, also known as MAX2) encodes a transcription regulator with DNA-binding activity, belonging to the leucine-rich repeat superfamily. In garden pea, this gene is associated with strigolactone and karrikin responses, bud dilation, shoot morphogenesis, brassinosteroid signalling, SCF complex assembly, and de-etiolation. It localises to the nucleus, SCF complex, and condensed chromosomes. Associations with agronomic traits include shoot branching, floral organ number, peduncle length, stem elongation, vegetative-to-reproductive phase transition, fruit quality, carotenoid content, total soluble sugar content, abscisic acid and cytokinin levels, lateral root number, root epidermal cell length, and cell membrane stability. Studies of related genes in other species link the family to strigolactone perception, axillary branching, drought resistance, root hair density, and pathogen resistance.
