CRISPR/Cas9 editing of endogenous banana streak virus in the B genome of Musa spp. overcomes a major challenge in banana breeding
This study reports a strategy to inactivate banana streak virus by editing the virus sequences. The regenerated genome-edited events showed mutations in the targeted sites with the potential to prevent proper transcription or/and translational into functional viral proteins. The study paves way for the improvement of B genome germplasm and its use in breeding programs to produce hybrids that can be globally disseminated.

Biofortification of field-grown cassava by engineering expression of an iron transporter and ferritin
Less than 10% of the estimated average requirement (EAR) for iron and zinc is provided by consumption of storage roots of the staple crop cassava in West African human populations. This study used genetic engineering to improve mineral micronutrient concentrations in cassava. The team also confirmed that the higher mineral levels don’t disappear during cooking.

Genetic diversity of symbiotic bacteria nodulating common bean (Phaseolus vulgaris) in western Kenya
Biological nitrogen fixation (BNF) in legumes plays a critical role in improving soil fertility. Despite this vital role, there is limited information on the genetic diversity and BNF of bacteria nodulating common bean. This study evaluated the genetic diversity and symbiotic nitrogen fixation of bacteria nodulating common bean in soils of Western Kenya.
