Chopping broccoli: Researchers lose paper on florets after readers raise questions

b&mclWith apologies to Dana Carvey, Bioorganic & Medicinal Chemistry Letters has chopped a 2012 paper on the molecular constituents of broccoli florets after readers evidently were forced to do the job of reviewers and point out fatal flaws in the study.

The article, “Two novel bioactive glucosinolates from Broccoli (Brassica oleracea L. var. italica) florets,” came from a group in South Korea and has yet to be cited, according to Thomson Scientific’s Web of Knowledge. But according to the retraction notice, after publication critics pointed out serious problems with the work. To wit: Continue reading Chopping broccoli: Researchers lose paper on florets after readers raise questions

Image manipulation leads to fifth retraction for plant research group

plant scienceA plant scientist at the Colorado State University has retracted a fifth paper.

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.

The last author of the now-retracted paper, Jorge Vivanco, has had four previous retractions, including one in Nature. He tells us: Continue reading Image manipulation leads to fifth retraction for plant research group

A complicated case involving two microbiology researchers at the National Autonomous University of Mexico (UNAM) appears to have come to some conclusion.

In November of last year, we reported that Continue reading “Not exoneration”: University reverses sanctions on husband-wife team found to have manipulated images

Plant journal withdraws paper — or does it?

mol plantThe temporary withdrawal of a Molecular Plant paper had us scratching our heads, but the issue seems to be explained by a glitch.

If you click on this version of “Application of the CRISPR–Cas System for Efficient Genome Engineering in Plants” (subscription required), you see this:

This paper has been withdrawn pending a decision by the Editorial Board

But that page also says that the latest version of the paper was published on October 3. Clicking on that version sends you to the paper, which begins: Continue reading Plant journal withdraws paper — or does it?

Plant journals uproot duplicate publications that authors used as a hedge

pmbpA group of researchers in India has lost two articles in the plant literature for shenanigans with duplicate submission.

One article, “Agrobacterium tumefaciens-mediated transformation and efficient regeneration of a timber yielding plant Dalbergia sissoo Roxb,” appeared online last June in the journal. The authors were from institutions in Orissa.

According to the retraction notice, the paper was a case of “thanks, but no thanks.” What’s worse, the researchers seem to be under the impression that they’ve done nothing wrong. Because they said so. Continue reading Plant journals uproot duplicate publications that authors used as a hedge

Image highjinx lead to retraction of hot pepper paper

pcp 913coverYou might be forgiven for thinking that the editors were describing a bad relationship rather than a paper gone wrong, the journal of Plant and Cell Physiology is retracting a 2004 article by Korean researchers who “manipulated and repeatedly used” micrographs.

The article, “Ornithine Decarboxylase Gene (CaODC1) is Specifically Induced during TMV-mediated but Salicylate-independent Resistant Response in Hot Pepper,” which appeared a s a short communication in the journal, came from the lab of Kyung-Hee Paek at Korea University.

According to the retraction notice: Continue reading Image highjinx lead to retraction of hot pepper paper

When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

colloids and surfaces bThe journal Colloids and Surfaces B: Biointerfaces has retracted a 2011 paper by a group of researchers in India who misappropriated — and then manhandled — a pair of images from a previously published article by other scientists.

The paper, “Synthesis and characterization of chitosan and grape polyphenols stabilized palladium nanoparticles and their antibacterial activity,” was written by authors from various institutions in Tamil Nadu, and appeared online in December 2011 and in print the following April. It has been cited three times, according to Thomson Scientific’s Web of Knowledge.

Here’s the abstract: Continue reading When two words colloid: “copied and manipulated” figures prompt retraction of nanoparticle paper

Figure error forces retraction of transgenic chickpea paper

pcrcoverThe humble chickpea has become one of the world’s most promising cash crops, so it’s no surprise that efforts are underway to make it even more humble, er, profitable, through genetic manipulation.

But one group of scientists made hummus out of their approach when they botched what evidently was a key element of a figure in their 2011 paper in Plant Cell Reports (PCR).

The article, “High-efficiency Agrobacterium-mediated transformation of chickpea (Cicer arietinum L.) and regeneration of insect-resistant transgenic plants,” came from researchers at the National Botanical Research Institute in Lucknow, India. Cited three times, according to Thomson Scientific’s Web of Knowledge, it purported to find that: Continue reading Figure error forces retraction of transgenic chickpea paper

Pesticide paper pulled for plagiarizing prior publication

intjnrpestmgmtThe International Journal of Pest Management has retracted a 2007 article on spinosad pesticides by researcher who stole much of the material from the thesis of a Kansas State University masters student.

But the retraction comes more than five years after a correction indicating that plagiarism had occurred — an odd interposition that we can’t quite figure out.

The article, “Insecticidal effect of spinosad dust against four stored product insect species in different grain commodities,” was written by Amin Nikpay, who, according to this website, is now with Arak Islamic Azad University, in Iran. It was published in the spring of 2007, but a few months later the journal issued the following notice: Continue reading Pesticide paper pulled for plagiarizing prior publication
