Figure 6. Model of HERK1/ANJ involvement in pollen tube reception.

Figure 6

  1. Overview of the contact point between the male and female gametophytes at pollen tube reception.
  2. Proposed mechanism(s) of pollen tube reception at a molecular level where HERK1 and ANJ form alternative co‐receptors with FER and LRE. Unknown components or interactions are shown in grey. Maternally or paternally derived RALFs could act as ligands for the HERK1‐LRE‐FER/ANJ‐LRE‐FER heterocomplexes.
  3. Four possible scenarios where kinase activity of HERK1/ANJ are not required for signal transduction during pollen tube reception. Red components indicate proteins active in signal transduction, while black proteins act as scaffolds for complex assembly. Each scenario is discussed in more detail in the discussion section.
