AP2-like ethylene-responsive transcription factor PLT2

Gene

PLT2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

Probably acts as a transcriptional activator. Binds to the GCC-box pathogenesis-related promoter element. May be involved in the regulation of gene expression by stress factors and by components of stress signal transduction pathways (By similarity). Master regulator of basal/root fate. Essential for root quiescent center (QC) and columella specification, stem cell activity, as well as for establishment of the stem cell niche during embryogenesis. Modulates the root polar auxin transport by regulating the distribution of PIN genes. Essential role in respecifying pattern and polarity in damaged roots. Direct target of the transcriptional corepressor TPL. Expression levels and patterns regulated post-transcriptionally by root meristem growth factors (RGFs).By similarity4 Publications

Expressioni

Tissue specificityi

Expressed in roots, seedlings, flowers, and siliques. Also detected at low levels in leaves. In roots, specifically detected in the distal root meristem, including the QC. This tissue specificity is regulated by auxin gradient and depends on PIN proteins.5 Publications

Developmental stagei

Accumulates in the basal embryo region that gives rise to hypocotyl, root, and root stem cells. Expressed in the root meristem throughout embryo development.2 Publications

Inductioni
