They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

A single limit dextrinase gene is expressed both in the developing endosperm and in germinated grains of barley. (1/4690)

The single gene encoding limit dextrinase (pullulan 6-glucanohydrolase; EC in barley (Hordeum vulgare) has 26 introns that range in size from 93 to 822 base pairs. The mature polypeptide encoded by the gene has 884 amino acid residues and a calculated molecular mass of 97,417 D. Limit dextrinase mRNA is abundant in gibberellic acid-treated aleurone layers and in germinated grain. Gibberellic acid response elements were found in the promoter region of the gene. These observations suggest that the enzyme participates in starch hydrolysis during endosperm mobilization in germinated grain. The mRNA encoding the enzyme is present at lower levels in the developing endosperm of immature grain, a location consistent with a role for limit dextrinase in starch synthesis. Enzyme activity was also detected in developing grain. The limit dextrinase has a presequence typical of transit peptides that target nascent polypeptides to amyloplasts, but this would not be expected to direct secretion of the mature enzyme from aleurone cells in germinated grain. It remains to be discovered how the enzyme is released from the aleurone and whether another enzyme, possibly of the isoamylase group, might be equally important for starch hydrolysis in germinated grain.  (+info)

Characterization of Chlamydomonas reinhardtii zygote-specific cDNAs that encode novel proteins containing ankyrin repeats and WW domains. (2/4690)

Genes that are expressed only in the young zygote are considered to be of great importance in the development of an isogamous green alga, Chlamydomonas reinhardtii. Clones representing the Zys3 gene were isolated from a cDNA library prepared using zygotes at 10 min after fertilization. Sequencing of Zys3 cDNA clones resulted in the isolation of two related molecular species. One of them encoded a protein that contained two kinds of protein-to-protein interaction motifs known as ankyrin repeats and WW domains. The other clone lacked the ankyrin repeats but was otherwise identical. These mRNA species began to accumulate simultaneously in cells beginning 10 min after fertilization, and reached maximum levels at about 4 h, after which time levels decreased markedly. Genomic DNA gel-blot analysis indicated that Zys3 was a single-copy gene. The Zys3 proteins exhibited parallel expression to the Zys3 mRNAs at first, appearing 2 h after mating, and reached maximum levels at more than 6 h, but persisted to at least 1 d. Immunocytochemical analysis revealed their localization in the endoplasmic reticulum, which suggests a role in the morphological changes of the endoplasmic reticulum or in the synthesis and transport of proteins to the Golgi apparatus or related vesicles.  (+info)

GTPase activity and biochemical characterization of a recombinant cotton fiber annexin. (3/4690)

A cDNA encoding annexin was isolated from a cotton (Gossypium hirsutum) fiber cDNA library. The cDNA was expressed in Escherichia coli, and the resultant recombinant protein was purified. We then investigated some biochemical properties of the recombinant annexin based on the current understanding of plant annexins. An "add-back experiment" was performed to study the effect of the recombinant annexin on beta-glucan synthase activity, but no effect was found. However, it was found that the recombinant annexin could display ATPase/GTPase activities. The recombinant annexin showed much higher GTPase than ATPase activity. Mg2+ was essential for these activities, whereas a high concentration of Ca2+ was inhibitory. A photolabeling assay showed that this annexin could bind GTP more specifically than ATP. The GTP-binding site on the annexin was mapped into the carboxyl-terminal fourth repeat of annexin from the photolabeling experiment using domain-deletion mutants of this annexin. Northern-blot analysis showed that the annexin gene was highly expressed in the elongation stages of cotton fiber differentiation, suggesting a role of this annexin in cell elongation.  (+info)

A multisubunit acetyl coenzyme A carboxylase from soybean. (4/4690)

A multisubunit form of acetyl coenzyme A (CoA) carboxylase (ACCase) from soybean (Glycine max) was characterized. The enzyme catalyzes the formation of malonyl CoA from acetyl CoA, a rate-limiting step in fatty acid biosynthesis. The four known components that constitute plastid ACCase are biotin carboxylase (BC), biotin carboxyl carrier protein (BCCP), and the alpha- and beta-subunits of carboxyltransferase (alpha- and beta-CT). At least three different cDNAs were isolated from germinating soybean seeds that encode BC, two that encode BCCP, and four that encode alpha-CT. Whereas BC, BCCP, and alpha-CT are products of nuclear genes, the DNA that encodes soybean beta-CT is located in chloroplasts. Translation products from cDNAs for BC, BCCP, and alpha-CT were imported into isolated pea (Pisum sativum) chloroplasts and became integrated into ACCase. Edman microsequence analysis of the subunits after import permitted the identification of the amino-terminal sequence of the mature protein after removal of the transit sequences. Antibodies specific for each of the chloroplast ACCase subunits were generated against products from the cDNAs expressed in bacteria. The antibodies permitted components of ACCase to be followed during fractionation of the chloroplast stroma. Even in the presence of 0.5 M KCl, a complex that contained BC plus BCCP emerged from Sephacryl 400 with an apparent molecular mass greater than about 800 kD. A second complex, which contained alpha- and beta-CT, was also recovered from the column, and it had an apparent molecular mass of greater than about 600 kD. By mixing the two complexes together at appropriate ratios, ACCase enzymatic activity was restored. Even higher ACCase activities were recovered by mixing complexes from pea and soybean. The results demonstrate that the active form of ACCase can be reassembled and that it could form a high-molecular-mass complex.  (+info)

Overexpression of a novel Arabidopsis gene related to putative zinc-transporter genes from animals can lead to enhanced zinc resistance and accumulation. (5/4690)

We describe the isolation of an Arabidopsis gene that is closely related to the animal ZnT genes (Zn transporter). The protein encoded by the ZAT (Zn transporter of Arabidopsis thaliana) gene has 398 amino acid residues and is predicted to have six membrane-spanning domains. To obtain evidence for the postulated function of the Arabidopsis gene, transgenic plants with the ZAT coding sequence under control of the cauliflower mosaic virus 35S promoter were analyzed. Plants obtained with ZAT in the sense orientation exhibited enhanced Zn resistance and strongly increased Zn content in the roots under high Zn exposure. Antisense mRNA-producing plants were viable, with a wild-type level of Zn resistance and content, like plants expressing a truncated coding sequence lacking the C-terminal cytoplasmic domain of the protein. The availability of ZAT can lead to a better understanding of the mechanism of Zn homeostasis and resistance in plants.  (+info)

The DNA binding site of the Dof protein NtBBF1 is essential for tissue-specific and auxin-regulated expression of the rolB oncogene in plants. (6/4690)

The Dof proteins are a large family of plant transcription factors that share a single highly conserved zinc finger. The tobacco Dof protein NtBBF1 was identified by its ability to bind to regulatory domain B in the promoter of the rolB oncogene. In this study, we show that the ACT T TA target sequence of NtBBF1 in domain B is necessary for tissue-specific expression of rolB. beta-Glucuronidase (GUS) activity of tobacco plants containing a rolB promoter-GUS fusion with a mutated NtBBF1 target sequence within domain B is almost completely suppressed in apical meristems and is severely abated in the vascular system. The ACT T TA motif is shown here also to be one of the cis-regulatory elements involved in auxin induction of rolB. The pattern of NtBBF1 expression in plants is remarkably similar to that of rolB, except in mesophyll cells of mature leaves, in which only NtBBF1 expression could be detected. Ectopic expression of rolB in mesophyll cells was achieved by particle gun delivery if the NtBBF1 binding sequence was intact. These data provide evidence that in the plant, a Dof protein DNA binding sequence acts as a transcriptional regulatory motif, and they point to NtBBF1 as the protein involved in mediating tissue-specific and auxin-inducible expression of rolB.  (+info)

Isolation and characterization of SYN1, a RAD21-like gene essential for meiosis in Arabidopsis. (7/4690)

The proper pairing, recombination, and segregation of chromosomes are central to meiosis and sexual reproduction. The syn1 mutation was previously identified as a synaptic mutant in a T-DNA-tagged population of plants. SYN1 has been isolated and found to exhibit similarity to Schizosaccharomyces pombe RAD21 and RAD21-like proteins, which are required for chromosome condensation and sister chromatid cohesion during mitosis. Plants homozygous for syn1 are male and female sterile and show defects in chromosome condensation and pairing beginning at leptonema of meiosis I. Fragmentation of the chromosomes was observed at metaphase I. Alternative promoters produced two SYN1 transcripts. One transcript was expressed at low levels in most tissues, whereas the other was expressed only in prebolting buds. DNA blot analyses suggest that Arabidopsis contains a small RAD21 gene family. Consistent with the DNA blot data, a second Arabidopsis RAD21-like gene has been identified. These results suggest that different RAD21-like proteins play essential roles in chromosome condensation and pairing during both meiosis and mitosis.  (+info)

The FLF MADS box gene: a repressor of flowering in Arabidopsis regulated by vernalization and methylation. (8/4690)

A MADS box gene, FLF (for FLOWERING LOCUS F ), isolated from a late-flowering, T-DNA-tagged Arabidopsis mutant, is a semidominant gene encoding a repressor of flowering. The FLF gene appears to integrate the vernalization-dependent and autonomous flowering pathways because its expression is regulated by genes in both pathways. The level of FLF mRNA is downregulated by vernalization and by a decrease in genomic DNA methylation, which is consistent with our previous suggestion that vernalization acts to induce flowering through changes in gene activity that are mediated through a reduction in DNA methylation. The flf-1 mutant requires a greater than normal amount of an exogenous gibberellin (GA3) to decrease flowering time compared with the wild type or with vernalization-responsive late-flowering mutants, suggesting that the FLF gene product may block the promotion of flowering by GAs. FLF maps to a region on chromosome 5 near the FLOWERING LOCUS C gene, which is a semidominant repressor of flowering in late-flowering ecotypes of Arabidopsis.  (+info)

There is a large literature on gene silencing, in which the transgenes remain in the genome, but are not expressed. More serious, from the safety point of view, is structural instability, the tendency for the transgenic DNA to come loose, to rearrange or become lost in part or in whole in successive generations [2,3]. This could change the transgenic line in unpredictable ways in terms of health and environmental risks. And it will increase the chance of transgenic DNA being taken up by unrelated species to make new combinations with their genetic material. Thats referred to as horizontal gene transfer and recombination. Transgenic DNA can spread to every species that interact with the transgenic plant, in the soil, in the air, in the mouth and gut and the respiratory tracts of animals including human beings ...

An experiment was conducted to investigate the effect of phytase transgenic corn (PTC) on intestinal microflora, and the fate of transgenic DNA and protein in the digesta and tissues of broilers. A total of 160 1-day-old Arbor Acres commercial male broilers were randomly assigned to 20 cages (8 chicks per cage) with 10 cages (replicates) for each treatment. Birds were fed with a diet containing either PTC (54.0% during 1-21 days and 61.0% during 22-42 days) or non-transgenic isogenic control corn (CC) for a duration of 42 days. There were no significant differences (P|0.05) between birds fed with the PTC diets and those fed with the CC diets in the quantities of aerobic bacteria, anaerobic bacteria, colibacillus and lactobacilli, or microbial diversities in the contents of ileum and cecum. Transgenic phyA2 DNA was not detected, but phyA2 protein was detected in the digesta of duodenum and jejunum of broilers fed with the PTC diets.

The significance of the 4C value (where C is the amount of DNA in the unreplicated haploid genome) in angiosperm plants is discussed. The DNA amount is a stable feature used in biosystematics. Although this parameter varies even in closely related taxa, there is no correlation between the DNA amount and the structural and functional organization of plants. The role of DNA amount, including excess DNA, in plant evolution is considered. Some rules governing the distribution of DNA amount among different plant taxa are postulated, together with the possibility of using the data in systematics, phylogeny, and solutions of problems of genetic apparatus organization and evolution. The decrease in DNA value per genome during plant evolution and the high level of species formation in taxa with large DNA values have been shown. Plant taxa with a small DNA value per genome have a high percentage and higher degree of polyploidy. The nature of the differential staining of euchromatin and heterochromatin bands of

Our knowledge of natural genetic variation is increasing at an extremely rapid pace, affording an opportunity to come to a much richer understanding of how effects of specific genes are dependent on the genetic background. To achieve a systematic understanding of such GxG interactions, it is desirable to develop genome editing tools that can be rapidly deployed across many different genetic varieties. We present an efficient CRISPR/Cas9 toolbox of super module (SM) vectors. These vectors are based on a previously described fluorescence protein marker expressed in seeds allowing identification of transgene-free mutants. We have used this vector series to delete genomic regions ranging from 1.7 to 13 kb in different natural accessions of the wild plant Arabidopsis thaliana. Based on results from 53 pairs of sgRNAs targeting individual nucleotide binding site leucine-rich repeat (NLR) genes, we provide a comprehensive overview of obtaining heritable deletions. The SM series of CRISPR/Cas9 vectors enables

DNA barcoding is a way to identify species via their species-specific genetic signatures. To do this for pollen, scientists sequence the DNA from a genetic region known to occur in all plants, but which varies from species to species. There are two parts to the standardized sequence we use for plant DNA barcoding. One is a section of the large subunit of a gene called ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcL for short). The other is a gene called maturase-K (matK). These genes are both essential for a plant to survive, and are thus present in all plants. Once an investigator sequences these gene regions from a sample, they can be compared to a database containing all the known DNA sequences of rbcL and matK to identify the species ...

Dormant viruses can be reactivated with genetically modified organisms - new research see also New Research Results on Genetically Modified Organisms The use of the Cauliflower Mosaic Viral promotor (CaMV) has the potential to reactivate dormant viruses or create new viruses in all species to which it is transferred. CaMV is known to be found in practically all current transgenic crops released commercially or undergoing field trials. This transgenic instability increases the possibility of promotion of an inappropriate over-expression of genes to the transferred species. The development of cancer may be one consequence of such inappropriate over-expression of genes. The scientists behind the research strongly recommend that all transgenic crops containing CaMV 35S or similar promoters which are recombinogenic should be immediately withdrawn from commercial production or open field trials. All products derived from such crops containing transgenic DNA should also be ...

Cultivated peanut is an allotetraploid with two nuclear genomic components, AA and BB. Although it is generally agreed that these component genomes are derived from diploid wild ancestors, the exact species involved has been a matter of some research and discussion. Although the evidence is not completely clear cut, analysis of data from molecular markers, cytogenetics, morphology and geographical distributions support that A. duranensis and A. ipaënsis are the direct ancestors of cultivated peanut [8, 30].. Genomic in situ hybridization (GISH) of A. hypogaea metaphase chromosomes with total genomic DNA from the AA genome of A. duranensis and the BB genome of A. ipaënsis allowed a clear differentiation of the A and B chromosomes. Firstly, this observation reinforces the evidence of the close relationship between the genomes of A. duranensis, A. ipaënsis and cultivated peanut. Secondly, since GISH relies largely on the hybridization of repetitive sequences, it also indicates that A. duranensis ...
The goals of this investigation were to identify and evaluate the use of polymorphic microsatellite marker (PMM) analysis for molecular typing of seventeen plant pathogenic fungi. Primers for di-, tri-, and tetranucleotide loci were designed directly from the recently published genomic sequence of Mycospherlla graminicola and Fusarium graminearum. A total of 20 new microsatellite primers as easy-to-score markers were developed. Microsatellite primer PCR (MP-PCR) yielded highly reproducible and complex genomic fingerprints, with several bands ranging in size from 200 to 3000 bp. Of the 20 primers tested, only (TAGG)4, (TCC)5 and (CA)7T produced a high number of polymorphic bands from either F. graminearum or F. culmorum. (ATG)5 led to successful amplifications in M. graminicola isolates collected from Germany. Percentage of polymorphic bands among Fusarium species ranged from 9 to 100%. Cluster analysis of banding patterns of the isolates corresponded well to the established species delineations based
and thus are genetically linked. The primers used to generate polymorphic bands were 3-anchored inter-simple sequence repeat primers which identified genomic microsatellites with a repeated motif of 3 nucleotides in length. The primers were used singly to amplify genomic segments which were flanked by inversely orientated, closely spaced, identical microsatellite sequences. One of the polymorphic bands, a 900 base pair band, was completely linked to the Sr39 and Lr35 rust resistance genes in the segregating population used in this study. After cloning and sequencing this polymorphic band, the inter-simple sequence repeat marker was converted to a sequence characterized amplified region marker by designing primer sets which amplify a single, easily resolved band from DNA of plants with Sr39/Lr35 genes. This marker is present in six wheat lines carrying the Sr39 and Lr35 genes on the translocated chromosome segment from Ae. speltoides, The marker has facilitated efforts to breed Canada Prairie ...

Arachis villosulicarpa is a perennial peanut species, which is cultivated by indigenous people in Mato Grosso, a state of Brazil. Its wild progenitor is thought to be Arachis pietrarellii. Although it is related to the common peanut, Arachis hypogaea, it was separately domesticated: A. villosulicarpa is diploid, whereas A. hypogaea is tetraploid. It is one of several species that might be used as gene source for plant breeding to improve the important cultivated peanut Arachis hypogaea. List of domesticated plants Galgaro, L.; Montenegro Valls, J. F.; Lopes, C. R. (1997). Study of the genetic variability and similarity among and within Arachis villosulicarpa, A. pietrarellii and A. hypogaea through isoenzyme analysis.

An allopolyploid is an individual having two or more complete sets of chromosomes derived from different species. Generation of allopolyploids might be rare because of the need to overcome limitations such as co-existing populations of parental lines, overcoming hybrid incompatibility, gametic non-reduction, and the requirement for chromosome doubling. However, allopolyploids are widely observed among plant species, so allopolyploids have succeeded in overcoming these limitations and may have a selective advantage. As techniques for making allopolyploids are developed, we can compare transcription, genome organization, and epigenetic modifications between synthesized allopolyploids and their direct parental lines or between several generations of allopolyploids. It has been suggested that divergence of transcription caused either genetically or epigenetically, which can contribute to plant phenotype, is important for the adaptation of allopolyploids.

My research interests focus on the regulation of plant gene expression in response to abiotic stress and extreme environments, with particular interest in chromatin structure, genome organization and epigenetic change. Venues associated with spaceflight provide an opportunity to explore plant genomic responses to an environment that is outside the evolutionary experience of terrestrial organisms. This unique platform presents a background by which adaptive metabolisms can be observed as they are crafted to cope with a stress de novo; providing a window into the origins of adaptive processes.. ...

Usually organisms that have a higher rate of reproduction than their competitors have an evolutionary advantage. Consequently, organisms can evolve to become simpler and thus multiply faster and produce more offspring, as they require fewer resources to reproduce. A good example are parasites such as Plasmodium - the parasite responsible for malaria - and mycoplasma; these organisms often dispense with traits that are made unnecessary through parasitism on a host.[7] A lineage can also dispense with complexity when a particular complex trait merely provides no selective advantage in a particular environment. Loss of this trait need not necessarily confer a selective advantage, but may be lost due to the accumulation of mutations if its loss does not confer an immediate selective disadvantage.[8] For example, a parasitic organism may dispense with the synthetic pathway of a metabolite where it can readily scavenge that metabolite from its host. Discarding this synthesis may not necessarily allow ...

  • Evidence for localized selection on the U. gibba gene complement, however, does not provide support for the existence of genome-wide selective forces that might favour reduction of nonessential, non-coding DNA. (
  • The plant mitochondrial genome is huge in comparison, the structure is much more complicated, the genes are sometimes duplicated, the gene expression mechanisms are not well-understood, and some mitochondria have no genomes at all - in our previous studies, we observed that they fuse with other mitochondria to exchange protein products and then separate again," said Arimura. (
  • New research into the plant's genome shows that it contains almost no noncoding DNA -- demonstrating that a complex life form can function without the so-called junk DNA. (
  • Repeated segments buried in the plant's DNA show them that the entire genome has been duplicated three times since its lineage split off from its common ancestor with the tomato and the grape -- and yet this regular doubling of the code hasn't increased its length. (
  • My reading of the simplest version of this is that they take some target DNA (e.g. derived from a plant genome, and possibly cut up and re-ligated to swap things around), and design a single 'forward' PCR primer and multiple 'reverse' primers that bind the target sequence at various positions. (
  • Examples are given for viruses with a single‐stranded DNA genome, either (a) linear ( Parvoviridae , genus Dependovirus ) or (b) circular ( Geminiviridae , genus Mastrevirus ), and with a double‐stranded DNA genome, either (c) linear ( Adenoviridae , genus Mastadenovirus ) or (d) circular ( Papovaviridae , genus Polyomavirus ). (
  • The sequences of these DNA snippets can be matched to corresponding stretches of DNA on a reference genome, in order to map precisely the spots where DNA-damage is under repair. (
  • One is that knocking out the excision repair system leads to an increase in plant genome mutations even when the plant is kept in the dark, away from UV or other forms of light. (
  • Researchers sequenced the genome of the gardenia, then looked at how the plant makes a compound called crocin. (
  • The T-DNA of the BIBAC vector can be transferred into the plant nuclear genome. (
  • Similarly, when DNA is damaged, a molecular general contractor oversees a network of genetic subcontractors to ensure that the diverse cellular tasks needed to protect and repair the genome are carried out correctly and on time. (
  • Now, researchers at the Salk Institute report which genes are turned on or off, and in which order, to orchestrate the cellular processes required to protect and repair the genome in response to DNA damage. (
  • This paper brings us one step closer to understanding how the response to DNA damage is coordinated over time to maintain genome stability. (
  • In addition to informing strategies to improve crop health by maintaining genome stability, this work may also shed light on conserved aspects of the DNA damage response in other organisms, as there are many parallels between SOG1 and a gene in animals that has a similar "general contractor" function--the p53 gene, a tumor suppressor known for its role in combating DNA damage to prevent cancer. (
  • The new study at UF's Florida Museum of Natural History analyzed 86 complete plastid genome sequences from a wide range of plant species. (
  • Genome sequencing is more time-consuming for plants than animals because plastid DNA is about 10 times larger than the mitochondrial DNA used in studying animal genomes. (

  • Every cell in a living organism contains a genome, which consists of genetic information coded in a double helix strand of the chemical DNA. (
  • In conjunction with an enhanced system for Agrobacterium-mediated plant transformation, a new binary bacterial artificial chromosome (BIBAC) vector has been developed that is capable of transferring at least 150 kb of foreign DNA into a plant nuclear genome. (
  • World's Largest Genome Belongs to Slow Growing Mountain Flower .html "It is an unremarkable and rather fragile plant, but a flowering herb that frustrates gardeners for being notoriously difficult to grow has stunned scientists after they discovered it has the world's largest genome. (
  • The bacterium Agrobacterium tumefaciens has been the workhorse in plant genome engineering. (
  • Customized replacement of native tumor-inducing (Ti) plasmid elements enabled insertion of a sequence of interest called Transfer-DNA (T-DNA) into any plant genome. (
  • In eukaryotes, DNA repair pathways help to maintain genome integrity and epigenomic patterns. (
  • Loss-of-function mutation in DDB2 leads to genome-wide DNA methylation alterations. (
  • NER comprises two subpathways, global genome repair ( GGR ) and transcription-coupled repair, both of which process bulky DNA lesions throughout the genome or along the transcribed strand of active genes, respectively ( Schärer, 2013 ). (
  • Our results show that particle acceleration can be used for the introduction of foreign DNA into the soybean genome and indicate the technique may be useful in the recovery of engineered plants by transformation of regenerable tissues. (
  • Sysmex has launched two new reagent kits - CyStain™ UV OxProtect and CyStain™ PI OxProtect - to determine ploidy content and genome size in plants that are sensitive to oxidative processes. (
  • Seeking to catch an arms-race maneuver in action, researchers have uncovered new evidence to explain how bacteria in the process of infecting a plant can shift molecular gears by excising specific genes from its genome to overcome the host plant's specific defenses. (
  • Studying interactions between strains of the halo-bright pathogen and bean plants, the researchers found that the pathogenic bacteria essentially kicks out a section of its genome when it senses that its presence has been detected by the plant's defense system. (
  • In their study, the authors identify within the halo-bright pathogen genome a special island of DNA that encodes one such offending protein. (
  • But this genomic island also encodes enzymes that, when switched on, snip the DNA on either side of the island, resulting in the excision of the entire island from the genome. (
  • Gardenia's newly sequenced genome highlights how evolutionary tinkering transforms plants into some of nature's great chemical-makers. (
  • It was exciting to uncover these molecular 'tricks of the trade' while researching the genome of a plant so important to traditional Chinese medicine, and now to modern biomedical research as well," says the study's co-corresponding author, Jingyuan Song, PhD, from the Engineering Research Center of Chinese Medicine Resource in China, who is also affiliated with the Chinese Academy of Medical Sciences and Peking Union Medical College. (
  • A prime example is the use of short, standardized regions of the genome as taxon barcodes for biological identification of plants. (
  • The routine generation of transgenic plants involves analysis of transgene integration into the host genome as well as the evaluation of the transgene expression using standard molecular techniques such as polymerase chain reaction (PCR), Southern blot, reverse transcription PCR (RT-PCR) and Enzyme Linked Immunosorbent Assay (ELISA) or Western blot.

  • Methods for identifying species by using short orthologous DNA sequences, known as "DNA barcodes," have been proposed and initiated to facilitate biodiversity studies, identify juveniles, associate sexes, and enhance forensic analyses. (
  • Engineered DNA sequences also have been suggested as exact identifiers and intellectual property tags for transgenic organisms ( 6 ). (
  • The main aim of DNA barcoding is to establish a shared community resource of DNA sequences that can be used for organismal identification and taxonomic clarification. (
  • About 35 percent cDNA sequences for plants match those for animals. (
  • The authors show that when AP1 proteins interact with each other to form AP1-AP1 homodimers, they bind to different DNA sequences than AP1-SEP3 heterodimers. (
  • Similarly, AG-AG homodimers bind to different DNA sequences than AG-SEP3 heterodimers. (
  • In addition, the degree of DNA bending intrinsic to these sequences influences their interactions with heterodimers. (
  • DNA specificity plot comparing the relative binding affinities of SELEX-seq sequences selected by SEP3-AG ( y axis) and SEP3-AP1 ( x axis). (
  • Although the correlation between the authors' in vitro data and previously published in vivo data was significant, several hundred DNA sequences interact with these transcription factors in vivo, which, as acknowledged by the authors, were not explained by SEP3 heterodimerization. (
