WOX1 — Medicago truncatula

Summary

MTR_8G095580 (MtWOX1) encodes a WUSCHEL-like homeodomain protein with DNA binding and transcription factor activity, and is also annotated with adenosylmethionine decarboxylase activity. Localised to the nucleus, it is associated with meristem maintenance, organogenesis, embryogenesis, floral organ and petal development, auxin transport, dedifferentiation, and phloem or xylem histogenesis. The gene is linked to polyamine, spermidine and spermine anabolism, as well as cell cycle phases. Associations with traits include root volume, root length, stem elongation, and drought tolerance. Phenotypic connections involve leaf adaxial-abaxial patterning, leaf blade outgrowth and flattening, leaf serration, flower development, plant height, meristem development, male sterility, fertility, and polyamine homeostasis. Studies of related genes in other species link the family to leaf margin development, cell proliferation, and lateral organ development.
