A uORF Represses the Transcription Factor AtHB1 in Aerial Tissues to Avoid a Deleterious Phenotype.

Plant physiology - 1 Nov 2017

Ribone Pamela A, Capella Matías, Arce Agustín L, Chan Raquel L

Abstract excerpt

AtHB1 is an Arabidopsis (Arabidopsis thaliana) homeodomain-leucine zipper transcription factor that participates in hypocotyl elongation under short-day conditions. Here, we show that its expression is posttranscriptionally regulated by an upstream open reading frame (uORF) located in its 5' untranslated region. This uORF encodes a highly conserved peptide (CPuORF) that is present in varied monocot and dicot...
