Authors retract two plant biology papers over duplicated images

without comments

Plant scientists have issued two retractions after noticing several images had been duplicated within and across the papers.

The papers both appeared in March 2002 in The Plant Cell and The Plant Journal.

The last author on both papers — Jonathan Jones, a professor and group leader at The Sainsbury Laboratory in Norwich, UK — took responsibility for the duplications. He told us:

As last author I was responsible for checking the papers but did not notice the similarities between figures in the different papers.  I regret this and took action as soon as I realized there was an issue. Both papers went through peer review and the issue was not picked up at that point either.

Susana Rivas, the first author on both papers, has collaborated with beleaguered plant scientist Oliver Voinnet — and was a second author on one of his eight retractions (which we covered here).

The editor-in-chief of TPJ Christoph Benning said that, after the authors contacted them, the journals looked into the issue, confirmed the duplications and then retracted the papers: Read the rest of this entry »

“There is an injustice in this article”

with 2 comments

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.

Talukdar, who is first and corresponding author on the 2007 paper and listed at the University of Calcutta in West Bengal, India, received his first retraction last July, which also cited suspected figure manipulation. Earlier this year, Talukdar received eight more retractions in seven different journals, all describing concerns over potential image duplication and manipulation.

Here’s the most recent retraction notice in Cytologia: Read the rest of this entry »

Plant biologist earns string of retractions, bringing total to 9

without comments

A pair of plant biologists has lost a string of papers over concerns about image manipulation. One author has added eight new retractions to his CV; the other has added five.

Last summer, a journal retracted another paper by the pair, also citing suspicions of image manipulation. The latest batch of retractions — issued by seven different journals — includes some papers that have been questioned on PubPeer.

Dibyendu Talukdar, listed at the University of Calcutta in West Bengal, India, is the sole author on three retracted papers. He shares five new retractions with Tulika Talukdar listed at the University of North Bengal. That brings their totals to nine and six, respectively. (We’re not sure if the Drs. Talukdar are related).

We’ll start with the papers they share: Read the rest of this entry »

Author duplicated a figure in three papers; two get retracted

without comments

Two journals have retracted two papers by the same group within months of each other, after editors were independently tipped off that they contained duplicated figures representing different experiments.

The two papers were published by PLOS ONE and The Egyptian Journal of Biochemistry and Molecular Biology (EJBMB) in 2015 and 2014, respectively. According to the PLOS ONE paper’s corresponding author, last author Saad A. Noeman from Tanta University in Egypt used the same Figure 1 in both papers, along with another 2013 paper in EJBMB.

Corresponding author Yasser S. El-Sayed, head of the Department of Forensic Medicine and Toxicology at Damanhour University in Egypt, told us he learned of this issue after a reader brought the figure manipulation and duplication concerns to PLOS ONE’s attention.

El-Sayed said that he tried to figure out what had happened.

Plant scientist logs 4 more notices over figure errors

without comments

Researchers in China have retracted a paper and corrected three others in a plant journal, citing problems with multiple figures.

Lixin Zhang, from the Chinese Academy of Sciences in Beijing, is corresponding author on all four papers, published by Plant PhysiologyWe’ve reported on three retractions and two corrections from Lixin Zhang and some of the same co-authors, bringing Zhang’s total to five retractions and four corrections, by our count.

According to the retraction notice, the authors agreed to pull the article because of figure-related “irregularities and inappropriate data handling” — but despite these issues, they remain confident that their conclusions are still valid.

Here’s the latest retraction notice, issued this February, for “Cooperation of LPA3 and LPA2 Is Essential for Photosystem II Assembly in Arabidopsis:”  Read the rest of this entry »

15-year old paper pulled for image problems

without comments

A group of researchers in France has been forced to retract their 2002 article in the Journal of Virology after learning that the paper was marred by multiple image problems.

The paper, “P0 of Beet Western Yellows Virus Is a Suppressor of Posttranscriptional Gene Silencing,” came from the lab of Veronique Ziegler-Graff, a plant biologist at the University Louis Pasteur, in Strasbourg. The authors attribute some of the image problems to “genuine mounting mistakes,” and have repeated the experiments to confirm the conclusion, as have other labs. However, the researchers couldn’t find all the original data from the 2002 paper.

Although the retraction statement points the finger at the first author, Sebastien Pfeffer, the list of contributors includes Patrice Dunoyer, a frequent collaborator of Olivier Voinnet, a high-profile plant biologist whose work has come under intense scrutiny.

Plant biologist loses three papers that made up a duplication ring

with one comment

A biologist in India has lost three papers that appear to have been part of a network of duplications.

One paper published in 2012 was retracted — at the researcher’s request — for copying from a 2010 paper of his. In turn, both papers were duplicated in a paper that was published in 2016, and retracted a few months later. That 2016 paper borrowed from another paper published last year, which was quickly retracted after we contacted the journal.

These papers — by Dilip Kumar Das, listed at T. M. Bhagalpur University in India — were flagged in March by a PubPeer commenter.

In December, Plant Cell, Tissue and Organ Culture (PCTOC) retracted Das’s 2012 paper; here’s the retraction notice:

“Crucial experiments” missing from retracted plant study

without comments

A 2016 study was retracted from a Frontiers journal after editors realized the authors had omitted experiments that didn’t support the hypothesis. 

Gearóid Ó Faoleán, ethics and integrity manager at Frontiers, which publishes Frontiers in Plant Science, told us:

In accordance with our complaints protocol, the Field Chief Editor led the investigation that resulted in the decision to retract the paper.

Plant journal flags fungus paper amid investigation

without comments

A journal has issued an expression of concern (EOC) for a recently published study after a probe identified “problems with the figure presentation.”

According to the EOC notice in New Phytologist, two figures in the paper contained “some anomalies,” and the corresponding author has acknowledged that there are problems with the images.

Here’s the EOC notice: Read the rest of this entry »

Journal issues three notices for plant biologist, two citing manipulation

without comments

Researchers have retracted a paper from a plant journal after a probe found problems with several figures.

According to the new retraction notice in The Plant Cell, some figures in the paper were manipulated, as well as “inappropriately duplicated and reused from a previous publication.” The authors assert that they believe the conclusions remain valid.

The journal has also issued two corrections that include some of the same authors — including one that cites inappropriate image manipulation.

Here’s the retraction notice, issued last month: Read the rest of this entry »
