The complexities of the ambient temperature flowering pathway are just beginning to be understood (Capovilla et al., 2015; Verhage et al., 2014). After vernalization or in vernalization-insensitive accessions, flowering in ambient temperatures is largely under control of the FLC-related FLOWERING LOCUS M (FLM) and residual FLC retains only a minor role (Gu et al., 2013; Balasubramanian et al., 2006; Blázquez et al., 2003; Lee et al., 2013). FLM controls flowering in the range between 5°C and 23°C and FLM can form, just like FLC, a flowering repressive complex with SVP (Lee et al., 2013; Posé et al., 2013). Besides FLM, as the dominant regulator, ambient temperature flowering is also regulated by the FLM-homologs MAF2 - MAF4 (Li et al., 2008; Gu et al., 2013; Lee et al., 2013; Ratcliffe et al., 2003; Airoldi et al., 2015). Conversely, loss-of-function mutations of SVP lead to early and temperature-insensitive flowering in the range between 5°C and 27°C (Lee et al., 2007, 2013).
