CORRECTION: Sabinene stereochemistry (Christopher Keeling, 28 October 2014)

In this article, the compound identified as (+)-sabinene should be corrected to (-)-sabinene throughout the text and figures. The error in the assignment of the stereochemistry of sabinene was due to a mistake by the commercial supplier who provided an incorrectly labeled authentic standard.

Table 2 footnotes require several corrections: 1) under ¿Observations¿, (11.002 cM) is footnote ¿b¿, not ¿a¿, 2) under ¿Observations¿, Tm2b should be Tm2a. This is a superscript, not a footnote, 3) in the footnotes section, ¿(Additional file 2: Figure S1).¿ is footnote ¿a¿, 4) current footnote ¿a¿ is not a footnote, it is a description of Table 2. read full comment

CORRECTION (K Bilyeu, 07 September 2011)

BMC Plant Biology 2010, 10:195doi:10.1186/1471-2229-10-195
Mutant alleles of FAD2-1A and FAD2-1B combine to produce soybeans with the high oleic acid seed oil trait

In the Methods, under the subsection FAD2-1B allele specific molecular marker assay, incorrect primer sequences were inadvertently listed:
Genotyping reactions were performed with a 5:2 asymmetric mix of primers (5'-ACTGCATCGAATAATACAAGCC-3' at 2 μM final concentration, and 5'-TGATATTGTCCCGTCCAGC-3' at 5 μM final concentration).

The correct sentence should read:
Genotyping reactions were performed with a 5:2 asymmetric mix of primers (5'- GGTTCTCCAAGGTTGCATTCTTACT -3' at 2 μM final concentration, and 5'- AGGGTTGTTCAGGTACTTGGTGT -3' at 5 μM final... read full comment

Are those plants clones? (Isidro Ovando, 15 March 2011)

I'm surprised by the results, specifically the follow: ..."A total number of 575 bands were identified by fAFLP analysis of all 162 individuals, out of which only 3 poly morphic bands were detected in 5 plants from China and India. This represents that only 0.52% of bands were polymorphic"..."RAPD, DAMD, SSR...SCAR...all failed to detect a single polymorphism in our samples...

Those results are equivalent to state that J. curcas studied are clones, which is difficult to explain, especially considering that samples came from seeds (...jatropha seeds were collected in five countries on three continents...)

I think the contributions of that investigation are really important about epigenetic variation in this species, but I think too that is unlikely the claim "...all the... read full comment

Why wasnt the RLK protein abundance measured? (David Lightfoot, 12 November 2010)

Melito et al., 2010 suggested that the RLK at Rhg1 was involved in root development but not the nematode development as shown by others (Ruben et al 2006 Afzal et al., 2008; Srour et al 2010). Sadly, the Melito et al study was flawed by the lack of an analysis of the target RLK protein abundance despite the available antibodies. The antibodies were offered freely and repeatedly to the PI. Stable transgenic soybean show the RLK is indeed a major resistance gene with effects on 3 pests, SCN, F.virguliforme and insect herbivory. See the first reports at Srour Ali , Simmonds Daina , David A Lightfoot (2010) The rhg1/Rfs2 locus isolated in transgenic plants. Plant and Animal Genome Conference Proceedings P704 : Transformation.

corrections to the article (Ann Loraine, 04 November 2010)

Dear Readers,
The article requires two corrections:
First, we included a discussion of an Arabidopsis gene we called SR40. The correct designation is SR45, not SR40.
Second, we implied that the ovule library is derived from a single cell type. Ovules actually consist of more than one cell type.
Very best wishes,
Ann Loraine

Introns could also affect mRNA stability (Deng-Ke Niu, 09 August 2010)

In this paper, the authors said "Introns stimulate gene expression in a wide range of organisms by increasing the levels of mature mRNA, without affecting mRNA stability". Surely, early studies did not observe significant effect of introns on mRNA stability. Those studies were based on a small number of genes. Later genome-wide analyses have shown that the mRNAs of intron-containing genes are more stable than those of intronless genes (1,2). In addition, there is also a experimental study showing that introducing an intron to a gene could enhance its mRNA stability (3).

Correct nomenclature of Na-thionin (cbgowda rayapuram, 23 January 2009)

Lately, a correction in the nomenclature of Na-thionin has been noticed by one of the readers of BMC Plant Biology (Dr. Sonny Larsson). It seems that there is a confusion about the peptide nomenclature (thionins)in the NCBI databases. And, as per the latest report,thionin (or PR-13) family of defense related plant peptides actually belong to plant defensin (or PR-12) family member. It has been reported that the 3D structure of plant thionin is very similar to defensins from insects and mammals (to a lesser degree). Hence the correct nomenclature for Na-thionin would be Na-defensin. We request the readers to note this change. We thank Dr Sonny Larsson for noticing this error and helping us to correct it. Further details on the naming and classification of... read full comment

Correction to Table 4 (James Ketudat Cairns, 29 September 2008)

In Table 4, the last two p-nitrophenyl glycosides should be alpha-linked (pNP-alpha-L-arabinoside and pNP-alpha-D-galactoside). The alpha's were accidently replaced by beta's during editing and I failed to catch it. I apologize to the readers for any confusion. read full comment

Addendum to clarify specificity of coordination (J Kenneth Hoober, 15 January 2003)

Addendum to Eggink, L.L., Park, H. and Hoober, J.K. 2001. The role of chlorophyll b in photosynthesis: Hypothesis. BMC Plant Biology 1:2.This paper proposed that specificity of binding of chlorophyll (Chl) a and b in the light-harvesting complexes (LHCs) of thylakoid membranes in chloroplasts is a consequence of the stronger Lewis acid property of the Mg in Chl b. Also, the stronger coordination bonds formed between Chl b and apoproteins would facilitate assembly and enhance stability of LHCs. Oxidation of the 7-methyl group of Chl a to the electronegative formyl group causes redistribution of the tetrapyrrole macrocycle π electrons toward the periphery of the molecule. As a result, the central Mg in Chl b has a more positive point charge than that in Chl a and would be expected... read full comment
