Abstract

Homeodomain-containing transcription factors are the important regulators of multicellular organism's development. Plant transcription factors WOX and KNOX play the key role in meristem maintenance, controlling cell proliferation and preventing differentiation. The precise mechanism of WOX and KNOX action hasn't been well studied, however these transcription factors were shown to play the important role in plant hormones homeostasis, cytokinins in particular. Plant transcription factors of KNOX group demonstrate the similarities in structure and are supposed have the common origin with animal transcription factors of MEIS group. This review describes WOX and KNOX transcription factor families, their interaction with plant hormones. The role of homeodomain-containing transcription factors in plant and animal tumor formation is discussed.
