“…The cellular functions of class I TCPs are less well explored, but several previous studies indicated that they are involved in a number of cellular or developmental processes. For example, Arabidopsis AtTCP14 and AtTCP16 participate in regulation of seed germination and pollen development, respectively (Takeda et al, 2006;Tatematsu et al, 2008a), and AtTCP20 and AtTCP15 are involved in the regulation of cell division, expansion, and differentiation (Hervé et al, 2009;Kieffer et al, 2011). In addition, several lines of evidence have demonstrated that the functions of class I TCP proteins are associated with phytohormone signaling, such as auxin, jasmonic acid (JA), and cytokinin (Kosugi and Ohashi, 2002;Danisman et al, 2012;Steiner et al, 2012;Uberti-Manassero et al, 2012).…”
