WOX1 — Medicago truncatula

Summary

MTR_8G107210, designated MtWOX1, encodes a WUSCHEL-like homeodomain transcription factor with DNA binding and transcription factor activity, localised to the nucleus. In barrel medic, MtWOX1 is associated with plant organ formation, leaf and petal development, embryogenesis, cell division and differentiation, and polyamine, spermidine and spermine biosynthesis. The gene is linked to stem elongation, plant height, leaf blade outgrowth and flattening, leaf serration and adaxial-abaxial patterning, flower development, male sterility and fertility, meristem development, drought tolerance and polyamine homeostasis. Studies of related genes in other species link the WOX1 family to leaf margin development, cell proliferation and lateral organ development.
