Analysis of pan-African Centres of excellence in health innovation highlights opportunities and challenges for local innovation and financing in the continent.

A pool of 38 pan-African Centres of Excellence (CoEs) in health innovation has been selected and recognized by the African Network for Drugs and Diagnostics Innovation (ANDI), through a competitive criteria based process. The process identified a number of opportunities and challenges for health R&D and innovation in the continent: i) it provides a direct evidence for the existence of innovation capability that can be leveraged to fill specific gaps in the continent; ii) it revealed a research and financing pattern that is largely fragmented and uncoordinated, and iii) it highlights the most frequent funders of health research in the continent. The CoEs are envisioned as an innovative network of public and private institutions with a critical mass of expertise and resources to support projects and a variety of activities for capacity building and scientific exchange, including hosting fellows, trainees, scientists on sabbaticals and exchange with other African and non-African institutions.

Selection ofMycosphaerella fijiensis-resistant cell lines from micro-cross sections of banana and plantain.

Anin vitro selection system using microcross sections of banana and plantain cultivars belonging to AAA and AAB genomic groups were used to produce plants resistant against the Black Sigatoka disease. The fungus resistant plantlets were obtained in a double selection system. This involved in a first step the use of a fungal crude filtrate and in the second step the purified host-specific toxin 2,4,8-trihydroxytetralone extracted from the fungusMycosphaerella fijiensis (M.
