Membrane-associated kinase regulators (MAKR) family contains seven proteins, most of which are important plant development regulators. MAKR6 is the only family member, whose functions are poorly understood. Previously, based on the patterns of MAKR6 transcriptional activity in Arabidopsis seedling tissues, we demonstrated that MAKR6 might be a new tissue-specific auxin-sensitive regulator of plant development. Regulation of transcription plays a pivotal role in gene expression patterning, and, in plants, it is often controlled by phytohormones. Here, we investigate the mechanisms of MAKR6 transcriptional regulation in Arabidopsis thaliana L. root. Our results show that MAKR6 transcription in the root is regulated by auxin and cytokinin, which are known as key regulators of the formation and maintenance of the bisymmetric organization of the vascular system in the root tip.
