Field decomposition of transgenic Bt maize residue and the impact on non-target soil invertebrates [PDF]

, 2018
Genetically modified Bacillus thuringiensis Berliner (Bt) maize (Zea mays L.) expressing Cry toxins against various target pests is now grown on more than 16 million hectares worldwide, but its potential effects on the soil ecosystem need to be further ...

Tritrophic interactions among Bt maize, an insect pest and entomopathogens: effects on development and survival of western corn rootworm [PDF]

, 2012
Agricultural systems often provide a model for testing ecological hypotheses, while ecological theory can enable more effective pest management. One of the best examples of this is the interaction between host-plant resistance and natural enemies.

Diversity and comparative phenology of Lepidoptera on Bt and non-Bt maize in South Africa

International Journal of Pest Management, 2008
Abstract The use of Bt maize could directly or indirectly affect non-target organisms. Assessment of the impacts of Bt crops is hampered by the lack of even the most basic checklist of the species present in most systems. In South Africa the maize agroecosystem is of particular interest because of the large area planted with Bt maize (Event MON810) for

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

The end of a myth – Bt (Cry1Ab) maize does not harm green lacewings

Frontiers in Plant Science, 2014
A concern with Bt-transgenic insect-resistant plants is their potential to harm non-target organisms. Early studies reported that Cry1Ab-producing Bt maize and purified Cry1Ab harmed larvae of the green lacewing, Chrysoperla carnea.

Genetic hitchhiking and resistance evolution to transgenic Bt toxins: insights from the African stalk borer Busseola fusca (Noctuidae) [PDF]

, 2016
Since transgenic crops expressing Bacillus thuringiensis (Bt) toxins were first released, resistance evolution leading to failure in control of pests populations has been observed in a number of species.

Environmental risk assessment of genetically modified plants - concepts and controversies [PDF]

, 2011
Background and purpose: In Europe, the EU Directive 2001/18/EC lays out the main provisions of environmental risk assessment (ERA) of genetically modified (GM) organisms that are interpreted very differently by different stakeholders. The purpose of this

Production and Purification of Mesenchymal Stem Cell‐Derived Extracellular Vesicles Using Preferential Exclusion Chromatography

ELECTROPHORESIS, EarlyView.
A scalable purification strategy using hydroxyl (OH) monolithic chromatography enables efficient isolation and direct concentration of MSC‐EVs from adherent and microcarrier‐based upstreams. This approach supports process scale‐up while ensuring high purity suitable for therapeutic EV manufacturing.
