In 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.
An 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.
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 »
Alejandra Bravo and Mario Soberon, a wife-husband research team at the National Autonomous University of Mexico (UNAM) who received sanctions — later lifted — for manipulating images in a number of papers have corrected another article.
The paper, “The mitogen-activated protein kinase p38 is involved in insect defense against Cry toxins from Bacillus thuringiensis,” appeared in Insect Biochemistry and Molecular Biology in 2010 and has been cited 23 times, according to Thomson Scientific’s Web of Knowledge. Here’s the correction notice: Read the rest of this entry »
When you think of drones, you probably think of deadly strikes in faraway lands. But what about studying crops?
Take “Use of digital photography from unmanned aerial vehicles for estimation of leaf area index in onion (Allium cepa L.),” a study published earlier this year in the European Journal of Agronomy by researchers from Spain: Read the rest of this entry »
With 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 »
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.
