WOX5 — Pisum sativum

Summary

PsWOX5 (PSAT2G034640) on garden pea chromosome 2LG1 encodes a WUSCHEL-like homeodomain protein with annotated methionine adenosyltransferase, chitinase, cytoskeletal motor, and transcription corepressor activities, and binds chromatin, DNA, RNA, and proteases. It is associated with dedifferentiation, axillary shoot meristem initiation, procambium histogenesis, stem cell maintenance, root hair tip growth, gibberellic acid homeostasis, lignin anabolism, and response to oomycetes. The gene has been linked to traits including seed set, seed coat morphology, shoot and root development, plant height, flowering time, lignin content, hormone sensitivities, abiotic stress response, and disease tolerance. Related genes in other species are associated with root meristem regulation, organ regeneration, callus formation, and embryogenesis.
