Experts suggest crops to replace those affected by climate change
Members of the banana family could become a vital food source for millions in developing countries, a new report suggests. The report was written by the Consultative Group on International Agricultural Research (CGIAR) after a request was made by the United Nations Framework Convention on Climate Change (UNFCCC). CGIAR looked at the effect of climate…
Discovery of genes for resistance to black Sigatoka in bananas
Researchers at Equador’s Biotechnology Research Centre (CIBE) have isolated the genes that are responsible for conferring resistance to black Sigatoka in the naturally resistant banana variety Musa Calcutta-4. Scientists have now been able to develop a protocol for the genetic transformation of banana cultivars Williams and Orito as well as the plantain cultivars Barraganete and…
Where did black sigatoka come from?
Black sigatoka, or black leaf streak disease, a disease of bananas and plantains caused by the fungus Mycosphaerella fijiensis, has caused widespread losses to banana crops over the past 50 years. A new study of the phylogeography of black sigatoka on banana leaves from around the world has helped to elucidate the recent origins of…
Creating super banana plants in the fight against nematode worms
Scientists in the UK and Uganda are developing a genetically modified (GM) variety of banana that is resistant to nematode worms, which account for a high percentage of banana crop losses in Africa. It is estimated that the losses of crops due to nematodes amounts to $125 billion a year. Currently, nematodes are controlled using…
