INDETERMINATE DOMAIN PROTEIN binding sequences in the 5'-untranslated region and promoter of the SCARECROW gene play crucial and distinct roles in regulating SCARECROW expression in roots and leaves.

Abstract excerpt

SCARECROW (SCR) and SHORT-ROOT (SHR), which belong to the GRAS transcription factor family, are key regulators of root and leaf growth and development. Despite the importance of SCR expression for proper plant development, the mechanism of SCR regulation has not been clarified. A previous study showed that an INDETERMINATE DOMAIN transcription factor, JACKDAW (JKD), is essential for the expression of SCR in...
