“…For example, such studies have led to the identification of putative Receptor-like Kinases (RLKs) (Sakamoto et al, 2012), putative SUN, OFP, GABBY, transcriptions factors (Huang et al, 2013), 146 putative ERF proteins (Pirrello et al, 2012), ERECTA genes (Villagarcia et al, 2012), and MAPK (Kong et al, 2012), helicase (Xu et al, 2013), WRKY (Huang et al, 2012), and nucleobase-ascorbate transporter (NAT) gene family members (Cai et al, 2014). With a comprehensive inventory of all sucrose and monosaccharide transporters encoded in the tomato genome, Reuscher et al (2014) identified 52 genes putatively encoding sugar transporter proteins in the tomato reference genome. All these sugar transporter protein families belong to the MFS family which is characterized by 12 transmembrane domains (TMDs) and driven by the protonmotive force.…”
