Researchers Develop Transgene-free Edited Banana |
|
|
|
Researchers from KU Leuven and the University of Liège developed a transgene-free edited banana using an Agrobacterium-mediated base editing approach. The study, published in New Phytologist, combines embryogenesis and chlorsulfuron selection to develop the edited plants.

Field Trials of Bt Cowpea Reveal Effective Resistance to Pest in Ghana |
|
|
|
Cowpea, an important crop in sub-Saharan Africa, faces devastating yield losses exceeding 80% because of the legume pod borer (LPB), Maruca vitrata. Cowpea varieties lack natural resistance to this particular pest, and conventional insecticides are often ineffective. Thus, a genetically modified (GM) cowpea (Sampea 20-T in Nigeria and Songotra T in Ghana) was developed to express the cry1Ab protein from Bacillus thuringiensis (Bt), providing effective resistance to LPB.

Transgenic Cowpea Confers Insect Resistance and Herbicide Tolerance |
|
|
|
A study published in Pest Management Science found that the genetically engineered cowpea line CAP5, expressing a fusion of Cry1Ab-Vip3A and CP4-EPSPS genes, demonstrated strong resistance against major lepidopteran pests and high tolerance to glyphosate. The findings of the study demonstrate the potential of developing insect-resistant and herbicide-tolerant cowpea events.
