Nesta revisao, sao abordados os mecanismos mais estudados e que apresentam o embasamento mais coerente, sendo eles: o reconhecimento celular promovido pelas plasmodesmas, as interacoes hormonais, as diferencas quantitativas e/ou qualitativas dos compostos fenolicos e a incompatibilidade causada pelos glicosideos cianogenicos.
As plasmodesmas sao extensoes tubulares da membrana plasmatica que atravessam a parede celular e conectam o citoplasma de celulas adjacentes, permitindo a comunicacao celular (PINA et al., 2009; PINA et al., 2012).
