CAM7 and HY5 genetically interact to regulate root growth and abscisic acid responses

Plant Signaling & Behavior

Abstract

CAM7, a member of CaM family in Arabidopsis, acts as a transcriptional regulator and enhances photomorphogenic growth and light regulated gene expression under various light conditions. HY5, a bZIP transcription factor, promotes photomorphogenesis at multiple wavelengths of light including far red, red, and blue light. Very recently, it has been shown that CAM7 and HY5 directly interact with the HY5 promoter to regulate the transcriptional activity of HY5 during Arabidopsis seedling development. In this study, we have investigated the root phenotype of cam7 hy5 double mutants and shown that CAM7 and HY5 genetically interact to control the root growth. We have further shown an interdependent function of HY5 and CAM7 in abscisic acid (ABA) responsiveness.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
