Light actively inhibits elongation in the hypocotyl, but promotes the growth and development of cotyledons, leaves, and roots. Distinct responses in specific tissues are maintained to some extent through the differential accumulation of photoreceptors such as phytochromes in distinct tissues and at different times during development (Adam et al., 1994; Somers and Quail, 1995a, 1995b; Goosey et al., 1997; Nagatani, 1997; Tóth et al., 2001; Sharrock and Clack, 2002; Baba-Kasai et al., 2014; van Gelderen et al., 2018); as well as in large part due to distinct signal transduction pathways downstream of photoreceptors in distinct tissues and organs (Bou-Torrent et al., 2008; Montgomery, 2008; Endo et al., 2016; Montgomery, 2016).
