In the intersection valve-mantle there is a pseudonodule
, only observable under the Scannig Electron Microscope (SEM) (Vidal, 2010, partim).

Host-plant responses to LCOs involve calcium as a second messenger via G protein and phospholipases C and D, and include root hair deformation, infection thread formation, cortical cell division, and the formation of pseudonodules
in some species (for recent reviews see Broughton et al., 2003; Limpens and Bisseling, 2003; Ferguson and Mathesius 2003).
