PI-55 is a specific cytokinin receptor inhibitor. PI-55 is structurally related to 6-benzylaminopurine (BAP) and was shown to inhibit competitively BAP binding on Arabidopsis-specific receptors CRE1/AHK4 and AHK3. PI-55 inhibits cytokinins induced haustorium formation and increased parasite aggressiveness.

How to use

In Vitro:

PI-55 at high concentrations (10 μM and 100 μM), which causes an incomplete blocking of early haustorial structure development, especially when cytokinin activity promotes it. PI-55 treatment also reduces the overall aggressiveness of P. ramosa when applied with BAP in comparison with BAP alone, suggesting that the signaling pathway leading to early haustorial structure formation involves histidine kinase receptors homologous to CRE1/AHK4 and AHK3.
