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.
Researchers are retracting two papers about molecular signalling in plants — including one from the Proceedings of the National Academy of Sciences (PNAS) — after discovering some inadvertent genotyping errors. But that was only after they used the problematic plants for an entire year without realizing they’d made a mistake.
In a pair of refreshingly transparent and detailed notices, the authors explain that the transgenic plants used in the papers included genotyping errors, which invalidated their findings. According to the notices, first author Man-Ho Oh generated the problematic transgenic plants, while corresponding author Steven C. Huber, based at University of Illinois, Urbana-Champaign (UIUC), took responsibility for omitting some critical oversight.
Huber told us that there were only two papers that used the transgenic plants in question, so no other retractions will be forthcoming.
A nearly ten-year-long series of investigations into a pair of plant physiologists who received millions in funding from the U.S. National Science Foundation has resulted in debarments of less than two years for each of the researchers.
The NSF Office of Inspector General recently posted its close-out report on its decision and a review of the University’s investigation, which had recommended a total of eight retractions or corrections. Although the investigator’s names have been redacted, the text of retractions and corrections quoted in the report corresponds to papers by Read the rest of this entry »
“[T]hese things can happen in every lab:” Mutant plant paper uprooted after authors correct their own findings
Three biologists at Tokyo Gakugei University in Japan have retracted a 2014 Frontiers in Plant Science paper on abnormal root growth in Arabidopsis “in light of new experimental evidence” showing they fingered the wrong mutant gene. The journal editors are hailing the retraction as an “excellent example of self-correction of the scientific record.”
The paper, “Mechanosensitive channel candidate MCA2 is involved in touch-induced root responses in Arabidopsis,” described the abnormally behaving roots of a mca2-null mutant Arabidopsis plant.
A subsequent string of experiments by the same research team—including DNA microarrays, RT-PCR, and a PCR-based genomic deletion analysis—demonstrated that two other mutations that somehow creeped into their experimental populations may have been to blame for the abnormal root behavior.
It’s a notably thorough and informative retraction notice from Frontiers, an open-access publisher with a history of badly handled and controversial retractions and publishing decisions. The notice describes the new experiments and the previous, erroneous results: Read the rest of this entry »
Here’s the notice for “Influence of ATP-binding cassette transporters in root exudation of phytoalexins, signals, and in disease resistance, a paper originally published in July 2012:
The Journal, Chief Editor and the Authors wish to retract the Original Research article cited above in its entirety. Based on information reported after publication, this article was found to have images that were inappropriately manipulated (Figure 1B: actin panel; Figure 6A: PR1, PR5; Figure 6B: AtATH6, AtATH10). The authors and the journal regret the errors and regret any inconvenience to the readers of Frontiers in Plant Science.
