A digital camera fitted with a hemispherical lens was used to generate canopy leaf area index (LAI) values for a banana (Musa spp.) field trial with the aim of establishing a method for monitoring stresses on tall crop plants. The trial in Uganda consisted of two cultivars susceptible to nematode...

As global populations continue to increase, agricultural productivity will be challenged to keep pace without
overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainabi...

In banana and plantain research, it is essential to establish embryogenic cell suspensions together with a highly efficient regeneration and transformation system. This article describes the development of an embryogenic cell suspension (ECS), regeneration, and transformation for plantain cv. “Go...
Plant parasitic nematodes impose a severe constraint on plantain and banana productivity; however, the sterile nature of many cultivars precludes conventional breeding for resistance. Transgenic plantain cv. Gonja manjaya (Musa AAB) plants, expressing a maize cystatin that inhibits nematode diges...

Banana production in Africa's great lakes region is threatened by the Banana Xanthomonas wilt (BXW) disease caused by Xanthomonas campestris pv. musacearum, a biotrophic pathogen. Transgenic banana plants, cv. “Gonja manjaya,” expressing stacked hypersensitive response-assisting protein gene (HRA...

Centromeres are specified by a centromere specific histone 3 (CENH3) protein, which exists in a complex environment, interacting with conserved proteins and rapidly evolving satellite DNA sequences. The interactions may become more challenging if multiple CENH3 versions are introduced into the zy...
Pests and diseases have become major constraints to smallholder banana production in the highlands of East Africa. Biotic challenges to banana cultivation include fungi, bacteria, viruses, nematodes and insects. Host-plant resistance, developed either by conventional breeding or by application of...

Although genetic transformation of clonally propagated crops has been widely studied as a tool for crop improvement and as a vital part of the development of functional genomics resources, there has been no report of any existing Agrobacterium-mediated transformation of yam (Dioscorea spp.) with ...

Agrobacteriummediated genetic transformation of yam (Dioscorea rotundata): an important tool for functional study of genes and crop improvement
Dioscorea rotundata, commonly known as white yam, is an important staple food crop widely cultivated in West Africa and provides food security to millions of people. Genetic improvements of this crop using the advanced biotechnology tools have been hampered hitherto by the recalcitrant nature of ...
