EMBO takes back Voinnet’s award, investigates other awardee who just lost a Nature Genetics paper

Screen Shot 2016-01-28 at 11.41.20 AMEMBO has taken back an award given to beleaguered plant biologist Olivier Voinnet in 2009, and is investigating a recent grantee who had a paper retracted from Nature Genetics yesterday.

The European Molecular Biology Organization (EMBO) “promotes excellence in the life sciences” in Europe, in part by awarding prizes to promising young scientists. Voinnet and Sonia Melo earned their awards by exhibiting potential as young scientists studying genetics — of plants and cancer, respectively — but now EMBO is skeptical of the papers that formed the basis of their applications.

Melo’s Installation Grant from EMBO was announced just last month, and consists of 50,000 Euros annually for three to five years. She is currently based at the University of Porto, in Portugal.

Voinnet’s problems are well-documented on this blog — 21 corrections, seven retractions, and two investigations. Earlier this week, we reported that the Swiss National Science Foundation had cut off Voinnet’s funding, and banned him for three years.

Science publishes Voinnet’s 19th, 20th, and 21st corrections

351-6271-coverProminent plant biologist Olivier Voinnet has issued three more corrections in this week’s issue of Science.

Collectively, the papers have earned more than 1400 citations, according to Thomson Scientific’s Web of Knowledge.

By our count, he’s now at 21 corrections and seven retractions, following months of questions about his work. He’s been the subject of an investigation that found he “breached his duty of care,” and another which found evidence of scientific misconduct.

One correction goes against the recommendation of the ETH Commission to retract the paper for “well documented intentional manipulations.” According to the correction note, the incorrect figures did not “alter the data in any material way that could be construed to benefit the results and their conclusions.” That correction is the only one of the three for which Voinnet takes full responsibility.

The other two corrections place the responsibility on  Continue reading Science publishes Voinnet’s 19th, 20th, and 21st corrections

Paper on pine tree genetics chopped for duplication

naslovna_vol6_no2A paper on genetic variability in Austrian pine trees apparently didn’t vary enough from other work.

The journal is now retracting the 2012 paper for having significant overlap with another paper published in 2008. Another researcher pointed out the duplication — which was unintentional, according to the note, the result of

an apparent failure in communication between the co-authors on both papers which caused the papers to be overlapped.

The overlapping papers share a first author, Aleksandar Lucic, who works at the Institute of Forestry in Serbia. The other author on both papers is Vasilije Isajev, at the Faculty of Forestry in Belgrade.

“Analysis of Genetic Variability of Austrian Pine (Pinus nigra Arnold) in Serbia Using Protein Markers” was published in South-East European Forestry. The journal is not indexed on Thomson Scientific’s Web of Knowledge.

Here’s the retraction note:

Paper on plant immunity can’t fight off manipulation

10.cover

A paper on how plants respond to bacteria has an invader of its own — data manipulation.

The “irregularities and inappropriate data manipulation” were found in a figure produced by the first author, Ching-Wei Chen, whose LinkedIn page lists him as a student at the National Taiwan University. The authors were unable to replicate the results in the figure, according to the note.

The authors are doing more experiments to verify the main conclusion of the 2014 paper, “The Arabidopsis Malectin-Like Leucine-Rich Repeat Receptor-Like Kinase IOS1 Associates with the Pattern Recognition Receptors FLS2 and EFR and Is Critical for Priming of Pattern-Triggered Immunity,” published in The Plant Cell.

The retraction note explains the what happened in more detail:

Voinnet’s notice count grows, as he notches his 18th correction

home_coverOlivier Voinnet, a high-profile plant scientist at ETH Zurich, has earned a mega-correction. It wrapped up a rough year for the biologist, which included his seventh retraction, and a CNRS investigation that found evidence of misconduct.

This latest correction, to a paper on the mechanisms behind RNA silencing in Arabidopsis, was published in RNA. The 2007 paper has been cited 101 times, according to Thomson Scientific’s Web of Knowledge. The corrigendum modifies three figures in total.

The notice is long, so we’re not going to post the whole thing here. The first error in “Transitivity in Arabidopsis can be primed, requires the redundant action of the antiviral Dicer-like 4 and Dicer-like 2, and is compromised by viral-encoded suppressor proteins” is a clarification to a legend:

Paper claiming extra CO2 doesn’t always lower plant nutrients pulled for errors

11Authors have retracted a large meta-analysis claiming that rising levels of carbon dioxide don’t always reduce nutrients in plants.

After commenters on PubPeer raised concerns, the authors say they found several unintentional errors in their data that could “significantly change conclusions” of the paper in Plant Ecology, according to the retraction note.

The paper found that the impact of rising CO2 depends on many factors — in some cases, extra amounts of this greenhouse gas could actually increase plant nutrients. Trouble is, some of the papers that cited the now-retracted article came to the opposite conclusion: Increased carbon dioxide levels do decrease plant nutrients.

The retraction note for “CO2 effects on plant nutrient concentration depend on plant functional group and available nitrogen: a meta-analysis” explains some of the specifics of the errors, and says that there was “no evidence of bias:”

Investigation ends in 6th retraction for Voinnet

PLOS PathogensA sixth paper co-authored by plant researcher Olivier Voinnet has been retracted by PLOS Pathogens “following an investigation into concerns.”

The investigation found “several band duplications” in one figure provided by fifth author, Patrice Dunoyer, who took it from “the Master thesis of a former student working under his supervision, without the prior consultation or consent of this student,” according to the notice. There was also an incorrect “loading control” in another figure, attributed to first author Raphael Sansregret and last author Kamal Bouarab. 

Voinnet and Bouarab, the study’s corresponding authors, took full responsibility for “the publication of this erroneous paper.”

Although investigators found that the raw data in the duplicated figure backed up its conclusions, “given the nature and extent of data manipulation,” the authors asked the journal to retract the paper .

Mirror image in plant study flagged on PubPeer grows into retraction

djs_mpmi_28_9_cover-online.inddA 2010 paper on plant fungus has been retracted after a comment on PubPeer revealed that a study image had been flipped over and reused to represent two different treatments.

In May, a commenter pointed out the plants in Figure 2a of the paper in the journal Molecular Plant-Microbe Interactions “look remarkably similar.” A commenter writing under the name of corresponding author, Yukio Tosa at Kobe University in Japan, posted a response two days later agreeing with the assessment and stating that the paper should be retracted.

The notice reads: Continue reading Mirror image in plant study flagged on PubPeer grows into retraction

Biologist banned by second publisher

TF

Plant researcher Jaime A. Teixeira da Silva has been banned from submitting papers to any journals published by Taylor & Francis. The reason: “continuing challenges” to their procedures and the use of “inflammatory language.”

This is the second time Teixeira da Silva has been banned by a publisher —  last year Elsevier journal Scientia Horticulturae told him that they refused to review his papers following “personal attacks and threats.”

Apparently, Taylor & Francis has too become frustrated with Teixeira da Silva’s communication strategy. Anthony Trioli, from Taylor & Francis, told Teixeira da Silva in an email (to which Teixeira da Silva copied us on his reply) that they would no longer accept his papers:

Plant paper pulled when authors can’t pay fees

KPSB_10_08_COVER.inddA paper on chicory plants — also known as “blue daisies” — won’t get its moment in the sun.

The “accepted author version” was published online in June, in Plant Signaling & Behavior. But before the so-called “version of record” could make it into an official issue of the journal — which is online-only — it was retracted.

Why? The authors apparently couldn’t pay the fees required to publish the paper. Here’s the short note, which is titled “Editorial Retraction:” Continue reading Plant paper pulled when authors can’t pay fees
