A proposed regulatory model of EjERF39 and EjMYB8 in low-temperature- induced lignification of loquat fruit. Low-temperature (0 °C) storage activates the expression of EjERF39 (a direct activator of lignin biosynthesis via the DRE motif) and EjMYB8 (a previously reported lignin-related activator; Wang et al. 2016). EjERF39 and EjMYB8, which are involved in the regulation of lignification, can also form protein–protein complexes. Solid arrows indicate significant activations; dashed arrows indicate the absence of activations.
