Plant paper retracted when new species turns out not to be so new

with 8 comments

nordic plantIn December, a group of biologists in Thailand published a paper in the Nordic Journal of Botany heralding the discovery of a new species of plant:

Bauhinia saksuwaniae, a new species from northeastern Thailand is described and illustrated. It appears to be an endemic and endangered species. The new species is obviously distinct from all other species of Thai Bauhinia in having large orbicular persistent bracteoles forming a cup-shape and enclosing a young floral bud.

with 83 comments

Scientia HorticulturaeAn Elsevier journal has taken “the exceptional step of ceasing to communicate” with a scientist-critic after a series of “unfounded personal attacks and threats.” The move means that the journal, Scientia Horticulturae, will not review any papers that include the critic, Jaime A. Teixeira da Silva, as an author.

Here is the text of the letter (pdf here, obtained from an anonymous source), signed by Gert Jan-Geraeds:

Last year, we wrote about two retractions by Pamela Ronald and colleagues, after the group found that a bacterial strain they’d been using was contaminated.

The group has now published a paper in PeerJ following their investigation into what went wrong. Ronald tells us the new paper, titled “The Xanthomonas Ax21 protein is processed by the general secretory system and is secreted in association with outer membrane vesicles,” Read the rest of this entry »

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

with 13 comments

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: Read the rest of this entry »

Image manipulation leads to fifth retraction for plant research group

with 11 comments

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: Read the rest of this entry »

Plant journal withdraws paper — or does it?

with 2 comments

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: Read the rest of this entry »
