WOX1 — Pisum sativum

Summary

PsWOX1 (PSAT7G002400) on chromosome 7LG7 encodes a WUSCHEL-like homeodomain transcription factor with DNA binding and transcription factor activity, as well as annotated adenosylmethionine decarboxylase activity. It localises to the nucleus and is associated with meristem maintenance, organogenesis, plant organ formation and development, lateral growth, petal development, dedifferentiation, cell differentiation, nodulation, and polyamine, spermidine and spermine anabolism. The gene is also linked to viral genome replication. Phenotypically, PsWOX1 has been connected to leaf blade outgrowth, leaf flattening, leaf adaxial-abaxial patterning, leaf serration development, flower development, meristem development, plant height, male sterility, fertility, and polyamine homeostasis. Additionally, it is associated with drought tolerance. Studies of related genes in other species link the WOX1 family to leaf margin development, cell proliferation, and lateral organ development.
