New genome editing technology, such as zinc-finger nucleases and CRISPR/Cas9, are revolutionizing reverse genetics studies because they allow fast and precise genetic modifications in many species. However, they require efficient transformation and selection methods. This is notably a problem for algae…

Celiac disease is a debilitating autoimmune disease in which antigens in plant gliadins (one type of gluten protein) stimulate production of antibodies that inflame the lining of the small intestine. In wheat, α-gliadin (the main cause of the sensitivity) is encoded by more than 100 genes, thwarting…

Nuclear accidents in recent years such as the Fukushima incident during the tsunami in 2011 revealed the detrimental effects of leaked radioactive cesium (Cs) in environmental soil and water. Due to Cs's chemical similarity with potassium, an essential macronutrient for plants, cesium is taken up by…

This week’s blog was written by Dr Craig Cormick, the Creative Director of ThinkOutsideThe. He is one of Australia’s leading science communicators, with over 30 years’ experience working with agencies such as CSIRO, Questacon and Federal Government Departments.   So what do you think…

Most fruits form after pollination, making their production vulnerable to pollinator presence. Parthenocarpy is the development of fruit that occurs in the absence of pollination. Genes that enable parthenocarpy have been identified, including a tomato gene involved in auxin responses SlIAA9. Ueta et…

When is a genome-edited plant a GMO (and subject to GMO-restrictions)? Wolter and Puchta summarize two important papers that show that CRISPR/Cas genome editing can be achieved in wheat and rice without the introduction of foreign DNA (making these plants “not GMO”), by delivering complexes of enzyme…

The gene-editing technology CRISPR/Cas, which introduces double-strand breaks that are repaired by non-homologous end joining (NHEJ), is best known for the promise it holds in modifying an organism’s DNA without the introduction of exogenous genes. However, as Puchta describes (Curr. Opin. Plant Biol.…

Slides from the recent CRISPR/Cas workshop held at the GARNet2016 meeting are now available to download. Organized by Vladimir Nekrasov and Amanda Hopes (The Sainsbury Laboratory/University of East Anglia, UK), the workshop title was, "Introduction to CRISPR-Cas, troubleshooting target design…
