Banana and plantain (Musa spp.) are major staple foods and a source of income for millions in tropical and subtropical regions. Most of the bananas and plantains grown worldwide are produced by small-scale farmers for home consumption or sale in local and regional markets. Many pests and diseases...
Banana (Musa sp.) represents one of the most important world food crops after maize, rice, wheat and cassava. Many pests and diseases have significantly affected banana cultivation. Banana Xanthomonas wilt (BXW), caused by the bacterium Xanthomonas campestris pv. musacearum, is one of the most im...

Banana is an important staple food crop feeding more than 100 million Africans, but is subject to severe productivity constraints due to a range of pests and diseases. Banana Xanthomonas wilt caused by Xanthomonas campestris pv. musacearum is capable of entirely destroying a plantation while nema...

Pseudocercospora fijiensis, causal agent of the black Sigatoka disease (BSD) of Musa spp., has spread globally since its discovery in Fiji 1963 to all the banana and plantain growing areas across the globe. It is becoming the most damaging and economically important disease of this crop. The iden...

Enset (Ensete ventricosum (Welw.) Cheesman) is an economically important staple food crop in Ethiopia, especially in the southern and southwestern regions. It is called “false banana” due to its resemblance to banana, but inability to produce any edible fruit. The crop is clonally propagated usin...

Plant parasitic nematodes impose losses of up to 70% on plantains and cooking bananas in Africa.
Application of nematicides is inappropriate and resistant cultivars are unavailable. Where grown, demand
for plantain is more than for other staple crops. Confined field testing demonstrated that tran...

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...
