The editors of a plant biology journal have retracted a 2007 paper because of “an injustice.”

According to the notice, the editors of Cytologia found evidence of “apparent figure manipulation,” and decided to retract the paper.

This marks the 10th retraction for plant biologist Dibyendu Talukdar.

Sato was not an author on the meta-analyses published in 2008 and 2011; he was, however, first and lead author on all the retracted papers referenced in the notices. The notices state that the trio of authors on the meta-analyses:
