Retraction to: Plant Cell, Tissue and Organ Culture (PCTOC) (2015) 122:509–516 https://doi.org/10.1007/s11240-015-0770-y

The editor has retracted this article [1] because a scientific error was made in the identification of the species referred to in the study. The plant studied is not Canscora decussata, as stated in the manuscript, but rather Canscora diffusa (Vahl) R.Br. ex Roem. & Schult. Because of this unintentional error, the scientific content of the article is no longer reliable. All authors agree to this retraction.
