Abstract: The transcription factor TCP (TEOSINTE BRANCHED1, CYCLOIDEA, and PCF) family has bHLH (basic-Helix-Loop-Helix) secondary domain. According to the different base sequences of binding sites, the TCP family was divided into two categories:Ι Class (GGNCCCAC) and II class (GTGGNCC). The transcription factor TCP4 is one of the II class members of plant-specific transcription factors. TCP4 regulates the growth and development of plants, affects the synthesis of a variety of plant hormones, and participates in the regulation of plant resistance. This article reviews the involvement of transcription factor TCP4 interacts with other plant transcription factor families in plant seed germination, epidermal hair differentiation, leaf morphology, flowering and other important plant growth and development processes.So plants adapt to the changing growth environment of the outside world. Plants will encounter various environments in the process of growth and development, resulting in stress. Under abiotic stress, transcription factor TCP4 combines with cis acting elements of functional genes to regulate its expression and regulate the synthesis of plant hormones, so as to participate in plant stress resistance. During plant development, TCP4 also has spatio-temporal limited expression patterns, which improve the possibility of TCP4 triggering or antagonizing hormone signal transduction locally. It provides a reference and theoretical basis for how transcription factor TCP4 regulates plant growth and development and accurately participates in plant hormone synthesis, and has important guiding significance for plant growth regulation and breeding of excellent varieties under stress.

Key words: Transcription factor TCP4, Growth and development, Stress resistance regulation, Plant hormones
