FLOT2 and infection: Some of the genes activated by this transcriptional node are Early Nodulin11 (ENOD11), which is involved in the infection processes (Journet et al., 2001), and the Flotillins (FLOT) FLOT2 and FLOT4, which are involved in the formation of the infection thread, a tubular structure essential for rhizobial infection of the root cells (Haney and Long, 2010) (Figure 1).
