A newly discovered gene confers resistance to the Ug99 strain causing stem rust in wheat

Researchers at the University of California, Davis, led by Professor Jorge Dubcovsky, have recently discovered gene conferring resistance to the Ug99 strain of wheat stem rust that has caused significant losses in recent years in North Africa and Asia, becoming a world-wide threat. Wheat is essential for feeding humanity, and …

What makes soil, soil? Researchers find hidden clues in DNA

Researchers at the Netherlands Institute of Ecology (NIOO-KNAW) and The University of Manchester, UK, are using DNA sequencing to unlock the secrets of the world’s different soils and, for the first time, analysing ecological patterns and microbial communities on a global scale. The research team, made up of 36 scientists …

Team grows world-first Panama disease-resistant bananas

Australian researchers have developed and grown modified Cavendish bananas resistant to the devastating soil-borne fungus Fusarium wilt tropical race 4 (TR4), also known as Panama disease. In a world-first GM field trial conducted in heavily TR4-infested soil, one Cavendish line transformed with a gene taken from a wild banana and …

Researchers generate tomatoes with enhanced antioxidant properties by genetic engineering

The School of Biological Sciences, Faculty of Science, the University of Hong Kong (HKU), in collaboration with the Institut de Biologie Moléculaire des Plantes (CNRS, Strasbourg, France), has identified a new strategy to simultaneously enhance health-promoting vitamin E by ~6-fold and double both provitamin A and lycopene contents in tomatoes, …

Development of seedless tomatoes based on parthenocarpy and the application of genome editing with CRISPR/Cas9

Parthenocarpy in horticultural crops is an important trait of considerable importance for various industries related to agriculture as well as food quality. A team of scientists led by Risa Ueta of the Tokushima University in Japan developed a strategy for breeding of parthenocarpy in tomato based on the CRISPR/Cas9 genome …

Pumpkin genomes sequenced, revealing uncommon evolutionary history

Cucurbita crops are used as a staple food in many developing countries and are consumed all over the world. Scientists at Boyce Thompson Institute (BTI), USA and National Engineering Research Center for Vegetables, China have sequenced the genomes of two important pumpkin species, Cucurbita maxima and Cucurbita moschata. The finished genomes appear in …
