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. Both transgenic phyA2 DNA and protein fragments were not found in the

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 http://www.scup.no/mehd/ho 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 ...
Rice is a cereal plant and staple food for most Indonesian people. One of the causes of the problem is decrease of wetland and lowland area which have impact on national level production. One of the efforts to increase rice production is selection to get desired trait. Regression and correlation analysis to determined the relationship among characters that can be used as a consideration for selection criterion. The purpose of this study is to know the relationships between morphological and agronomic characters in rice plant of F2 generation.

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.

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.
