Abstract
Callose is a vital component in plant biology, contributing to essential processes like pollen maturation and defense against pathogens. However, misconceptions surrounding callose staining persist, particularly regarding the role of aniline blue. It is now known that commercial aniline blue contains sirofluor, and it is this fluorophore, rather than aniline blue itself, that is responsible for the observed fluorescence during callose detection.
