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 …

Plant geneticists develop a new application of CRISPR to break yield barriers in crops

Scientists at Cold Spring Harbor Laboratory (CSHL), USA have harnessed the still untapped power of genome editing to improve agricultural crops. Using tomato as an example, they have mobilized CRISPR/Cas9 technology to rapidly generate variants of the plant that display a broad continuum of three separate, agriculturally important traits: fruit …

New oat variety helps reduce cholesterol

Researchers from the South Australian Research and Development Institute (SARDI) have created a new oat variety with high yield and increased beta glucan content. The new Kowari variety is of a dwarf-type, with an increased content of beta-glucan compared to other varieties. Beta glucans are natural sugar compounds that help …

Uncovering genetic network underlying important traits in soybean – a way towards accelerated breeding

Correlations between different traits and interactions between genes represent a major challenge to modern breeding. In a number of cases, traits of yield and quality are controlled by complex networks consisting of multiple loci. As a result, there is a close correlation among many complex traits resulting in heritable covariance …
