PLT2 — Arabidopsis thaliana

Summary

AT1G51190, also known as PLT2 or PLETHORA 2, encodes a transcription factor of the AP2/ERF domain family that localises to the nucleus and binds DNA, cis-regulatory regions and proteins. In Arabidopsis thaliana, PLT2 is associated with quiescent center specification, root stem cell maintenance and root meristem maintenance, and is associated with stem cell development, cellularization, stem cell renewal, root regeneration, cell polarization, pattern specification, organ growth, acropetal auxin transport, cytokinin anabolism, sulfation, sulfate assimilation, sulfur metabolism, mycose metabolism and S phase. The gene has been linked to numerous traits including root length, root thickness, plant height, drought sensitivity, water use efficiency, auxin content, callus induction, endosperm morphology, root phototropism, and meristem tissue development. Studies of related genes in other species connect the family to root growth, stem cell regulation and meristem function.
