Abstract
Cassava is the second most important staple food crop in terms
of per capita calories consumed in Africa and holds potential for
climate change adaptation. Unfortunately, productivity in East
and Central Africa is severely constrained by two viral diseases:
cassava mosaic disease (CMD) and cassava brown streak disease
(CBSD). CBSD was first reported in 1936 from northeast Tanzania.
For approximately 70 years, CBSD was restricted to coastal
East Africa and so had a relatively low impact on food security
compared with CMD. However, at the turn of the 21st century,
CBSD re-emerged further inland, in areas around Lake Victoria,
and it has since spread through many East and Central African
countries, causing high yield losses and jeopardizing the food
security of subsistence farmers. This recent re-emergence has
attracted intense scientific interest, with studies shedding light
on CBSD viral epidemiology, sequence diversity, host interactions
and potential sources of resistance within the cassava genome.
This review reflects on 80 years of CBSD research history (1936–
2016) with a timeline of key events. We provide insights into current
CBSD knowledge, management efforts and future prospects
for improved understanding needed to underpin effective control
and mitigation of impacts on food security.
