PLT1 — Arabidopsis thaliana

Summary

AT3G20840, also known as PLT1 or PLETHORA 1, encodes an AP2/ERF domain-containing transcription factor that binds DNA and localises to the nucleus. In Arabidopsis thaliana, PLT1 is associated with stem cell development and proliferation, root meristem maintenance, and cell polarization. The gene has been linked to root regeneration, pattern specification, organ growth, and auxin transport. PLT1 is associated with traits including root length, thickness, and development, plant height, drought sensitivity, water use efficiency, callus induction, and lignin biosynthesis. It is also associated with shoot regeneration, root hydrotropism, and root stem cell niche maintenance. Related genes in other species link the family to root stem cell specification, meristem formation, and embryonic pattern formation.
