Circular dichroism (CD) analysis of the effect of carbendazim on the secondary structures of P. xanthii α-tubulin and β-tubulin. MBC-sensitive and MBC-resistant β-tubulins and α-tubulin were incubated in the absence (■) or presence of 0.5 (), 1.5 (○) and 3.3 mM (▲) carbendazim. Each spectrum represents the average of three scans.
