Sugar Responsible and Tissue Specific Expression of a Gene Encoding AtCIPK14, an Arabidopsis CBL-Interacting Protein Kinase

Abstract

Expression of AtCIPK14 (an Arabidopsis CBL-interacting protein kinase 14) was induced by metabolic sugars. Two A/T-rich sequences similar to elements involved in sugar-inducible expression of other genes were found within the −183 bp 5′ region of the AtCIPK14 promoter that was responsible for the sugar induction. Histochemical analysis using a reporter gene indicated vascular-specific expression of AtCIPK14.
