Concerns have been raised about the potential effects of transgenic introductions on the genetic diversity of crop landraces and wild relatives in areas of crop origin and diversification, as this diversity is considered essential for global food security. Direct effects on non-target species, and the possibility of unintentionally transferring traits of ecological relevance onto landraces and wild relatives have also been sources of concern. The degree of genetic connectivity between…

Contemporary evolution of maize landraces and their wild relatives influenced by gene flow with modern maize varieties
TLDR
It is shown here that regulations promoting the adoption of modern cultivars can promote rapid changes in the genetic pools of indigenous landraces (LRs) and crop wild relatives (WRs) and should foster monitoring strategies and policies that use and safeguard the genetic diversity of maize and its WRs at their center of origin.
Detecting adventitious transgenic events in a maize center of diversity
TLDR
This research could not detect, at the 95% probability level, transgenes in farmers' fields in the valley of Barranca, where there were recent claims of authorized transgenic maize grown.
Transgenes in Mexican maize: molecular evidence and methodological considerations for GMO detection in landrace populations
TLDR
Analytical and sampling considerations help explain discrepancies among different detection efforts, and provide considerations for the establishment of monitoring protocols to detect the presence of transgenes among structured populations of landraces, suggest the persistence or re‐introduction of transGenes up until 2004 in this area.
Absence of detectable transgenes in local landraces of maize in Oaxaca, Mexico (2003-2004).
TLDR
It is concluded that transgenic maize seeds were absent or extremely rare in the sampled fields, providing a much-needed preliminary baseline for understanding the biological, socioeconomic, and ethical implications of the inadvertent dispersal of transgenes from the United States and elsewhere to local landraces of maize in Mexico.
Ecological risk assessment of genetically modified strawberries - the hybridization potential between cultivated and wild strawberries
TLDR
It could be shown that clonal reproduction is of great importance for growth and maintenance of F. vesca populations, whereas sexual reproduction seems to be insignificant for population growth within established populations.
New Genes in Traditional Seed Systems: Diffusion, Detectability and Persistence of Transgenes in a Maize Metapopulation
TLDR
A spatially explicit population genetic model is used to evaluate the importance of seed flow as a determinant of the long-term fate of transgenes in traditional seed systems and finds that in spite of the spatial complexities of the modeled system, persistence probabilities under positive selection are estimated quite well by existing theory.
Impact of ecological factors on the initial invasion of Bt transgenes into wild populations of birdseed rape (Brassica rapa)
TLDR
It is concluded that high-density patches of highly damaged wild plants are the most vulnerable to Bt-transgene invasion and should be monitored early to detect potential transgene spread.
Persistent Agrobiodiversity on Genetically Modified Cotton Farms in Telangana, India
TLDR
This paper draws on surveys, field interviews, and ethnography conducted among randomly sampled Bt cotton farmers to show the full range of economic plants cultivated on Warangal GM farms, arguing that some farmers have been able to preserve agrobiodiversity despite the pressures of GM cotton cash cropping.
Impact of genetically modified crops on rhizosphere microorganisms and processes: A review focusing on Bt cotton
TLDR
This review collated and synthesized all available information on the microbiological and biochemical effects of GM crops on soil biota with a special focus on GM Bt-cotton and explored the plausibility of horizontal gene transfer in soil.
Evaluation proposal of possible impact of transgene accumulation in Mexican maize landraces.
TLDR
This assay proposes a test of the hypothesis of a damage deleterious threshold of transgene accumulation in each MML, and discusses the biological, agronomic and molecular evaluation of the genotypes under study.

Gene Flow and Introgression from Domesticated Plants into Their Wild Relatives
TLDR
A literature review of the world's most important food crops shows that 12 of these crops hybridize with wild relatives in some part of their agricultural distribution, and suggests ways of assessing the likelihood of hybridization, introgression, and the potential for undesirable gene flow from crops into weeds or rare species.
Molecular Evidence for Gene Flow among Zea Species
TLDR
The available evidence for gene flow between crops and their relatives provides a context for beginning to make realistic assessments of the risk of introgression.
The limits of selection during maize domestication
TLDR
The results help to explain why maize is such a variable crop, and suggest that maize domestication required hundreds of years, and confirm previous evidence that maize was domesticated from Balsas teosinte of southwestern Mexico.

TLDR
It is proposed that transgene integration at multiple clustered DNA replication forks could account for the observed interspersion of transgenic DNA with host genomic DNA within transgenic loci.
Event Specific Transgene Detection in Bt11 Corn by Quantitative PCR at the Integration Site
TLDR
The integration border was subsequently used to develop a novel and unambiguous PCR detection system covering the integration border at the 5′ site of the transgene, and the genomic sequence showed high similarities with a corn-specific 180 bp knob-associated repeat region.
Of genes and genomes and the origin of maize.
TLDR
Three independent lines of research are poised to shed light on the molecular basis of this spectacular transformation of maize, determining the structure and origin of the maize genome, understanding the role of transposable elements in maize evolution and elucidating the genetic basis for morphological differences between maize and its wild ancestor teosinte.
Transgenic pollen harms monarch larvae
TLDR
In a laboratory assay, it is found that larvae of the monarch butterfly, Danaus plexippus, reared on milkweed leaves dusted with pollen from Bt corn, ate less, grew more slowly and suffered higher mortality than larvae rearing on leaves dusting with untransformed corn pollen or on leaves without pollen.
From Teosinte to Maize: The Catastrophic Sexual Transmutation
TLDR
Maize, the only cereal with unisexual inflorescences, evolved through a sudden epigenetic sexual transmutation involving condensation of primary branches, which brought their tassels into the zone of female expression, leading to strong apical dominance and a catastrophic shift in nutrient allocation.
Detection of genetically modified organisms (GMOs) by PCR: a brief review of methodologies available
TLDR
The Polymerase Chain Reaction (PCR) method offers the advantage of detecting DNA molecules which are more thermostable than proteins, which is one of the sought advantages by the gene transfer.
A method of detecting recombinant DNAs from four lines of genetically modified maize.
TLDR
A method using polymerase chain reaction (PCR) was designed for the detection of genetically modified maize, and three insect-resistant GM-maize lines were distinguishable on the basis of the expected lengths of their amplicons.
