Herbicide Resistance Gene In Black-Grass and Rye-Grass Identified

BBSRC (Biotechnology and Biological Sciences Research Council) and Syngenta funded scientists at the University of York and University of Durham have discovered a gene called AmGSTF1 that plays a key role in controlling multiple herbicide resistance in black-grass (Alopecurus myosuroides) and annual rye-grass (Lolium rigidum). Now the gene that confers resistance has been identified, it…

Watermelon Genome Could Hold the Key to Improved Varieties With Fewer Pest Problems

A research team led by the Beijing Academy of Agriculture and Forestry Sciences have produced the complete genomic sequence of watermelon (Citrullus lanatus). It is hoped that the genomic data from this study will shape future research into watermelon genetics and provide a good resource for crop genetics and future plant breeding projects, resulting in…

Fungi just as effective as pesticides at controlling crop pest

Researchers at Swansea University have found a strain of fungi that could replace harmful pesticides in the control of the European crane fly (Tipula paludosa). The effects of 17 strains of entomopathogenic fungi, chlorpyrifos-based pesticides and a nematode worm were compared. The pesticides and fungal strain V1005 Metarhizium robertsii were both found to be 100%…

Pest-fighting Anthocyanins

U.S. Department of Agriculture (USDA) scientists in Illinois, USA, are investigating the role of anthocyanins in pest-control. They believe that the plant pigment can adversely affect crop pests such as the corn earworm caterpillar and the cabbage looper caterpillar that feed on it. Anthocyanins are a plant pigment which give blackcurrants and flowers, such as…
