The number of genetically modified (GM) events for canola, maize, and soybean has been steadily increasing. Real-time PCR is widely used for the detection and quantification of individual GM events. Digital PCR (dPCR) has also been used for absolute

In this study, we report an updated panel of 32 DNA markers used for identification of wheat varieties and assess their performance in the OpenArray and SmartChip high-throughput genotyping systems. While both systems are unique and offer different a

Low-level detection and quantification of genetically engineered (GE) traits with polymerase chain reaction (PCR) is challenging. For unapproved GE events, any level of detection is not acceptable in some countries because of zero tolerance. Droplet

Droplet digital PCR (ddPCR) has been used for absolute quantification of genetically engineered (GE) events. Absolute quantification of GE events by duplex ddPCR requires the use of appropriate primers and probes for target and reference gene sequenc

The number of genetically modified organisms (GMOs) on the market is steadily increasing. Because of regulation of cultivation and trade of GMOs in several countries, there is pressure for their accurate detection and quantification. Today, DNA-based

Low level presence of unapproved genetically engineered (GE) materials in non-GE grains has been a challenge for grain importers and exporters and many countries also have regulatory requirements for use and cultivation of GE crops. Digital PCR has b

Regulations and labeling laws established by many countries for genetically engineered (GE) events necessitate the development of effective testing methods. Both real-time quantitative PCR (RT-qPCR) and digital PCR (dPCR) have been used for the detec

Seven commercially available DNA extraction kits were compared with a cetyltrimethylammonium bromide (CTAB)method to determine the suitability of the extracted DNA for RainDrop digital PCR (dPCR) and real-time PCR (RT-PCR) quantification of OXY235 ca

Real-time PCR is commonly used for quantification of genetically engineered (GE) materials. Digital PCR (dPCR) assays have an advantage over real-time quantitative PCR assays in terms of sensitivity and precision. For meaningful real-time PCR results

In order to address the hypothesis that seeds from ecologically and geographically diverse plants harbor characteristic epiphytic microbiota, we characterized the bacterial and fungal microbiota associated with Triticum and Brassica seed surfaces. Th
