SALT TOLERANCE HOMOLOG2, a B-box protein in Arabidopsis that activates transcription and positively regulates light-mediated development.

The Plant cell - 1 Oct 2007

Datta Sourav, Hettiarachchi Chamari, Johansson Henrik, Holm Magnus

Abstract excerpt

CONSTITUTIVELY PHOTOMORPHOGENIC1 (COP1) and ELONGATED HYPOCOTYL5 (HY5) are two major regulators of light signaling in plants. Here, we identify SALT TOLERANCE HOMOLOG2 (STH2) as a gene that interacts genetically with both of these key regulators. STH2 encodes a B-box-containing protein that interacts physically with HY5 in yeast and in plant cells. Whereas STH2 is uniformly nuclear by itself, it shows a...
