Cassava virus resistance breakthrough for Africa
by Abigail Rumsey in The Plantwise Blog
One of the worst diseases of the tuber crop, cassava, in sub-Saharan Africa is Cassava brown streak disease (CBSD). Since its resurgence in East Africa in recent years, it is now spreading to Central and Western Africa. The other major disease of cassava in this region, Cassava mosaic disease (CMD), can also cause widespread damage [...]... Read more »

Earthworm-farmer friendship, redefined
by Abigail Rumsey in The Plantwise Blog
Earthworms are known as farmers’ best friends because of the multitude of services they provide that improve soil health and consequently plant health. The density of earthworms in the soil is considered to be a good indicator of a healthy soil because they improve many soil attributes like structure, water holding capacity, moisture content etc., and also increase nutrient availability and degrade pesticide residues. As scientists understand these ‘ecosystem services’ provided by earthwor........ Read more »

Watermelon Genome Could Hold the Key to Improved Varieties With Fewer Pest Problems
by Charlotte Elston in The Plantwise Blog
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 [...]...

Plant Pest Interactions: How Soybean Aphids Trick Soybean Plant Defences
by Charlotte Elston in The Plantwise Blog
Following on from a previous blog on the interactions between soybean plants and soybean pests, new research on soybean (Glycine max) responses to the soybean aphid (Aphis glycines) published in Molecular Plant-Microbe Interactions has revealed some of the complex and fascinating interactions between pests and their plant hosts. This recent research led by Dr Gustavo Macintosh and [...]... Read more »

Colorado Potato Beetles Left With A Sour Taste As Clover Is Found To Be As Effective As Pesticides
by Charlotte Elston in The Plantwise Blog
Eggplant or aubergine (Solanum melongena) is a crop often attacked by the Colorado Potato Beetle (Leptinotarsa decemlineata), a major insect pest of plants from the Solanaceae family including potato, tomato and eggplant throughout North America, Europe and Asia. This insect pest is exceptionally destructive to crops and readily develops resistance to a wide variety of [...]... Read more »

The Soybean Gene: Scientists Discover the Key to Nematode Resistant Soybeans
by Charlotte Elston in The Plantwise Blog
Soybean (Glycine max) is an important crop that provides a sustainable source of protein and oil worldwide in countries such as the USA, Brazil, Argentina, India and many African countries, including Nigeria, South Africa and Uganda. The soybean cyst nematode Heterodera glycines is a microscopic roundworm that feeds on the roots of soybean and is [...]... Read more »

Coffee Production in Hot Water- The Impacts of Climate Change on the Future of Coffee Crops
by Charlotte Elston in The Plantwise Blog
Coffee (Coffea) is the one of the world’s favourite drinks and the second most traded commodity after oil, accounting for annual retail value of US$ 90 billion. The two main species used in the production of coffee are Arabica coffee (Coffea arabica), which accounts for 70% of coffee production, and Robusta coffee (Coffea canephora). The [...]... Read more »

Slicing Into The Bread Wheat Genome
by Charlotte Elston in The Plantwise Blog
Bread wheat (Triticum aestivum) is a globally important crop that accounts for 20% of the calories consumed by the world’s human population. Major work is underway to increase wheat production by expanding knowledge of the wheat genome and analysing key traits, however due to the large size and great complexity of the bread wheat genome [...]...
