Abstract:

14-3-3 proteins are a highly conserved family of acidic proteins encoded by different genes in eukaryotic organisms. After interacting with the target proteins through the phosphorylation sites, 14-3-3 proteins influence the stability, subcellular localization, or interactions with other proteins of the target protein, thereby regulating its function. Various isoforms of 14-3-3 proteins have been found in different species, and these isoforms influence the processes such as plant growth and development. In this review, we summarize the type, subcellular localization, and expression patterns of 14-3-3 proteins in plants, with a specific focus on the functions of 14-3-3 proteins in plant hormone signaling, growth and development, and stress response. The aim of this review is to provide a theoretical foundation for further systematic research on 14-3-3 proteins.

Key words: 14-3-3 proteins, hormone signaling, growth and development, stress response
