Once germination reaches the appropriate conditions, the haustorial disc is formed. This important structure supports the active photosynthetic process for growth and development. The central cells from the young haustorial system establish contact with the host and penetrate slowly in the cortex. An advanced stage of growth epicortical prolongations with abundant photosynthetic parenchyma were formed. At the cellular level the trophyc interphase system shows adaptations forming xylematic tissue, abundant sclereidas and vascular system that consists of helicoidals vessels. An interesting finding in this research is the presence of cell wall adaptations forming pits and ample plasmodesmata connections to exchange lipids in a two-way fluxe.
