BPA disrupted microtubules in all mitotic stages of Abies cephalonica.
Chromosomal aberrations were underlain by microtubule derangement under BPA stress.
Endoplasmic reticulum malformations reflected those of microtubules.
Microtubule recovery after oryzalin treatment was more effective in BPA than in water.
BPA-induced multipolar spindles are attributed to the centrosomal properties of gymnosperms.
