Genome-wide analysis of major intrinsic proteins in the tree plant Populus trichocarpa: Characterization of XIP subfamily of aquaporins from evolutionary perspectiveEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Due to whole genome duplication, Populus has the largest number of MIPs identified in any single species. Non-XIP MIPs are similar in all four plant species considered in this study. Small and weakly polar residues at the helix-helix interface are group conserved presumably to maintain the hourglass fold of MIP channels. Substitutions in ar/R selectivity filter, insertion/deletion in loop C, increasing basic nature of loop D and loss of introns are some of the events occurred during the evolution of dicot XIPs.

Comparative analysis of the complete sequence of the plastid genome of Parthenium argentatum and identification of DNA barcodes to differentiate Parthenium species and linesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: The genome sequence of the P. argentatum chloroplast will enrich the sequence resources of plastid genomes in commercial crops. The availability of the complete plastid genome sequence may facilitate transformation efficiency by using the precise sequence of endogenous flanking sequences and regulatory elements in chloroplast transformation vectors. The DNA barcoding study forms the foundation for genetic identification of commercially significant lines of P. argentatum that are important for producing latex.

Vitamin B6 deficient plants display increased sensitivity to high light and photo-oxidative stressEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: This study demonstrates that vitamin B6 has a function in the in vivo antioxidant defense of plants. Thus, the antioxidant activity of vitamin B6 inferred from in vitro studies is confirmed in planta. Together with the finding that chloroplasts contain vitamin B6 compounds, the data show that vitamin B6 functions as a photoprotector that limits 1O2 accumulation in high light and prevents 1O2-mediated oxidative damage.

Pollen development in Annona cherimola Mill. (Annonaceae). Implications for the evolution of aggregated pollenEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Pollen grouping could be the result of relatively minor ontogenetic changes beneficial for pollen transfer or/and protection from desiccation. Comparison of these events with those recorded in the recent pollen developmental mutants in Arabidopsis indicates that several failures during tetrad dissolution may convert to a common recurring phenotype that has evolved independently several times, whenever this grouping conferred advantages for pollen transfer.

Seed storage protein gene promoters contain conserved DNA motifs in Brassicaceae, Fabaceae and PoaceaeEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Seed storage protein gene promoter motifs are conserved in diverse species, and different plant families are characterized by a distinct combination of conserved motifs. The majority of discovered motifs match experimentally characterized cis-regulatory elements. These results provide a good starting point for further experimental analysis of plant seed-specific promoters and our methodology can be used to unravel more transcriptional regulatory mechanisms in plants and other eukaryotes.

Sampling nucleotide diversity in cottonEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: In this research, SNP and indel diversity is characterized for 270 single-copy polymorphic loci in cotton. A strategy for SNP discovery is defined to pre-screen loci for copy number and polymorphism. Our data indicate that the A and D genomes in both diploid and tetraploid cotton remain distinct from each such that homoeologs can be distinguished. This research provides mapped DNA markers for intra-specific crosses and introgression of exotic germplasm in cotton. (Source: BMC Plant Biology - Latest articles)

Phenolic compounds in ectomycorrhizal interaction of lignin modified silver birchEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: The down-regulation of BpCOMT in the 35S-PtCOMT lines caused a reduction in the syringyl/quaiacyl ratio of lignin, but no significant effect was seen in the composition or quantity of phenolic compounds that would have been caused by the expression of PtCOMT under the 35S or UbB1 promoter. Moreover, the detected alterations in the composition of lignin and secondary phenolic compounds had no effect on the interaction between silver birch and P. involutus.

Identification of flowering genes in strawberry, a perennial SD plantEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: We have shown that many central genetic components of the flowering pathways in Arabidopsis can be identified from strawberry. However, novel regulatory mechanisms exist, like SFL that functions as a switch between short-day/low temperature and long-day/high temperature flowering responses between the short-day genotype and the everbearing 'Baron Solemacher'. The identification of putative flowering gene homologs and AP1 as potential marker gene for floral initiation will strongly facilitate the exploration of strawberry flowering pathways.

Involvement of S-adenosylmethionine-dependent halide/thiol methyltransferase (HTMT) in methyl halide emissions from agricultural plants: isolation and characterization of an HTMT-coding gene from Raphanus sativus (daikon radish)Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: The present findings suggest that HMT/HTMT activity is present in several families of higher plants including Poaceae and Brassicaceae, and is involved in the formation of methyl halides. Moreover, it was found that the emission of methyl iodide from plants was affected by the iodide concentration in the cultures. The recombinant RsHTMT demonstrated enzymatic properties similar to those of Brassica oleracea HTMT, especially in terms of its high specificity for iodide, bisulfide, and thiocyanate ions. A survey of biogenic emissions of methyl halides strongly suggests that the HTM/HTMT reaction is the key to und...

Evaluation of protein pattern changes in roots and leaves of Zea mays plants in response to nitrate availability by two-dimensional gel electrophoresis analysisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: This work provides a first characterization of the proteome changes that occur in response to nitrate availability in leaves and roots of maize plants. According to previous studies, the work confirms the relationship between nitrogen and carbon metabolisms and it rises some intriguing questions, concerning the possible role of NO and lipoxygenase 10 in roots and leaves, respectively. Although further studies will be necessary, this proteomic analysis underlines the central role of post-translational events in modulating pivotal enzymes, such as PEPCase.

Systemic acquired resistance in soybean is regulated by two proteins, Orthologous to Arabidopsis NPR1Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Complementation analyses in Arabidopsis npr1-1 mutants revealed that homoeologous GmNPR1-1 and GmNPR1-2 genes are orthologous to Arabidopsis NPR1. Therefore, SAR pathway in soybean is most likely regulated by GmNPR1 genes. Substitution of Cys216 residue, essential for oligomer-monomer transition of Arabidopsis NPR1, with Ser and Leu residues in GmNPR1-1 and GmNPR1-2, respectively, suggested that there may be differences between the regulatory mechanisms of GmNPR1 and Arabidopsis NPR proteins.

Arabidopsis WRKY2 transcription factor mediates seed germination and postgermination arrest of development by abscisic acidEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: ABA hypersensitivity of the wrky2 mutants during seed germination and postgermination early seedling establishment is attributable to elevated mRNA levels of ABI5, ABI3 and ABI5-induced Em1 and Em6 in the mutants. WRKY2-mediated ABA responses are independent of miR159 and its target genes MYB33 and MYB101. ABI5, ABI3, ABA2 and ABA3 are important regulators of the transcripts of WRKY2 by ABA treatment. Our results suggest that WRKY2 transcription factor mediates seed germination and postgermination developmental arrest by ABA. (Source: BMC Plant Biology - Latest articles)

Conclusion: This is the first example of a genetic map in a cucurbit species that includes a major set of SNP markers discovered using ESTs. The PI161375 x 'Piel de sapo' melon genetic map has around 700 markers, of which more than 500 are gene-based markers (SNP, RFLP and SSR). This genetic map will be a central tool for the construction of the melon physical map, the step prior to sequencing the complete genome. Using the set of SNP markers, it was possible to define the genetic relationships within a collection of forty-eight melon accessions as efficiently as with SSR markers, and these markers may also be useful for c...

Tissue culture-induced transpositional activity of mPing is correlated with cytosine methylation in riceEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Our results documented that tissue culture-induced mPing activity in rice ssp. indica is correlated with alteration in cytosine methylation patterns at both random genomic loci and the elements' flanks, while the stability of mPing positively correlates with enhanced methylation levels of both the flanks and probably the elements per se. Thus, our results implicate a possible role of cytosine methylation in maintaining mPing stability under normal conditions, and in releasing the element's activity as a consequence of epigenetic perturbation in a locus-specific manner under certain stress conditions.

New sources of soybean seed meal and oil composition traits identified through TILLINGEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: The oligosaccharide phenotype controlled by the novel RS2 allele is similar to previously observed seed oligosaccharide phenotypes in RS2 mutant (PI 200508) allele-containing lines. Due to the anti-nutritional characteristics of raffinose and stachyose, this represents a positive change in seed composition. The fatty acid phenotype controlled by the novel FAD2-1A allele controls an increase in oleic acid in the seed oil, a phenotype also observed in a line previously characterized to have a null allele of the FAD2-1A gene.

Identification, functional characterization and developmental regulation of sesquiterpene synthases from sunflower capitate glandular trichomesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: This study functionally identified sesquiterpene synthase genes predominantly expressed in sunflower trichomes. Evidence for the transcriptional regulation of sesquiterpene synthase genes in trichome cells suggest a potential use for these specialized cells for the identification of further genes involved in the biosynthesis, transport, and regulation of sesquiterpene lactones.

Sequence diversity in three tomato species: SNPs, markers, and molecular evolutionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: We present a new analysis of the extensive tomato EST sequences available that represents the most comprehensive survey of sequence diversity across Solanum species to date. These SNPs, plus thousands of molecular makers designed to detect the polymorphisms are available to the community via a website. Evolutionary analyses on these polymorphism uncovered sets of genes potentially important for the evolution and domestication of tomato; interestingly these sets were enriched for genes involved in response to the environment.

Selection of reference genes for quantitative real time PCR expression studies in the apomictic and sexual grass Brachiaria brizanthaEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: In total, eight genes belonging to different cellular processes were tested. Out of them, BbrizTUB was the less stable while BbrizEF1 followed by BbrizUBCE were the more stable genes considering male and female reproductive tissues, spikelets, roots and leaves. Regarding the best reference genes for ovary tissues, where apomictic and sexual reproduction must occur, the best reference genes were BbrizUBCE, BbrizE1F4A and BbrizEF1. Our results provide crucial information for transcriptional analysis in the Brachiaria ssp, helping to improve the quality of gene expression data in these species, which constitute a...

A membrane-bound matrix metalloproteinase from Nicotiana tabacum cv. BY-2 is induced by bacterial pathogensEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Our biochemical analysis of NtMMP1 together with bioinformatic data on the primary sequence indicate that NtMMP1 is a constitutively-active protease. Given its induction in response to bacterial pathogens and its localization in the plasma membrane, we propose a role in pathogen defense at the cell periphery.

Phylogenetic analysis and molecular evolution of the dormancy associated MADS-box genes from peachEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Because all DAM genes are expressed in peach and are subjected to strong purifying selection we suggest that the duplicated genes have been maintained by subfunctionalization and/or neofunctionalization. In addition, this pattern of selection suggests that the DAM genes are important for peach growth and development. (Source: BMC Plant Biology - Latest articles)
