A role of TCP1 in the longitudinal elongation of leaves in Arabidopsis

Biosci Biotechnol Biochem. 2010;74(10):2145-7. doi: 10.1271/bbb.100442. Epub 2010 Oct 7.

Abstract

We clarified important roles of Arabidopsis TCP1, a member of the TEOSINTE BRANCHED1, CYCLOIDEA, and PCF (TCP) transcription factors, in the longitudinal elongation of petioles, rosette leaves and inflorescent stems. We found that the promoter of TCP1 was active in the cotyledonary petioles and the distal part of the expanding leaves, as well as the midrib region and the petiole.
