WOX1 — Medicago truncatula

Summary

MTR_3G088485 (MtWOX1) encodes a WUSCHEL-like homeodomain transcription factor 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, somatic embryogenesis, floral organ and petal development, dedifferentiation, auxin transport, and polyamine, spermidine and spermine anabolism. The gene is linked to traits including root volume, root length, stem elongation, drought tolerance, and phenotypes such as plant height, leaf blade outgrowth, leaf adaxial-abaxial patterning, leaf serration development, leaf flattening, flower development, male sterility, fertility, meristem development, and polyamine homeostasis. Studies of related genes in other species link the family to leaf margin development, cell proliferation and lateral organ development.
