Cassava brown streak disease (CBSD) is a leading cause of cassava yield losses across eastern and central Africa and is having a severe impact on food security across the region. Despite its importance, relatively little is known about the mechanisms behind CBSD viral infections. We have recently reported the construction of Cassava brown streak virus (CBSV) and Ugandan cassava brown streak.
Year 1: The Cassava Applied Research for Food Security in Northern Uganda project focuses on addressing challenges to increased cassava production namely low yields, limited acreage under cassava production per household, high post-harvest deterioration and low prices offered for fresh cassava roots and traditional dry chips among others. The project is an applied research project where NaCRRI.
In the framework of the RTB-ENDURE project and in collaboration with the NEXTGEN Cassava Project, Ugandan and Nigerian colleagues from the Ugandan National Agricultural Research Organization, IITA, and IIRR are now in Colombia to attend a training organized by CIAT for strengthening the capacities to assess the postharvest physiological deterioration of cassava and the feasibility of adopting.
Cassava brown streak virus disease (CBSD) is a damaging disease of cassava plants, and is especially troublesome in East Africa. It was first identified in 1936 in Tanzania, and has spread to other coastal areas of East Africa, from Kenya to Mozambique. Recently, it was found that two distinct viruses are responsible for the disease: cassava brown streak virus (CBSV) and Ugandan cassava brown.
Ugandan scientists have begun moving gene extracts into cassava cells in a first-of-its-kind research trial using the CRISPR-Cas9 gene editing tool to develop varieties that can resist cassava.
Despite the high economic value of cassava, most cultivars grown in Busia, including the yellow-root type, were landraces. Although some Ugandan farmers tend to continuously cultivate landraces for various specific traits, such cultivars are often highly susceptible to diseases and thus leading to.
Ripe dessert bananas, small in size and locally known as ndiizi, are mashed in a bowl and mixed with cassava flour to form a non-sticky dough. It is rolled to form a flat circular shape with a thickness of approximately two inches. A cookie-cutter is used to cut out circular shapes, which are deep-fried for three to five minutes or until golden brown. They are served hot. Since cassava has a.
The expanding cassava brown streak disease epidemic in East Africa is caused by two ipomoviruses, Cassava brown streak virus (CBSV; Monger et al., 2010) and Ugandan cassava brown streak virus (UCBSV; Winter et al., 2010). To verify the identity of the causal agent, symptom-bearing leaf samples of 17 affected plants were collected in March and June 2014. Total RNA was extracted from these.
In 2018, the cassava harvested area in Uganda stood at X ha, going up by X% against the previous year. Overall, the cassava harvested area continues to indicate a resilient increase. The most prominent rate of growth was recorded in 2012 with an increase of X% y-o-y. Cassava harvested area peaked in 2018 and is likely to continue its growth in the immediate term.
The Ugandan cassava customer is a discerning one with a great ability to select the best roots for consumption chosen by assessing color, texture, skin type, size and shape. For urban consumers in cities like Kampala and Entebbe the right variety of cassava, purchased within a few hours of harvest and grown in favorable conditions, is a delicacy and a must-have ingredient in many meals. For.
Cassava brown streak disease (CBSD) has emerged as the most important viral disease of cassava (Manihot esculenta) in Africa and is a major threat to food security.The expanding CBSD epidemic in East and Central Africa is caused by two ipomoviruses (family Potyviridae), Cassava brown streak virus (CBSV; Monger et al., 2010) and Ugandan cassava brown streak virus (UCBSV; Winter et al., 2010).
Cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) devastate cassava production in Africa. Severe CBSD infections may cause yield losses of between 70 and 100 per cent and for CMD, the yield loss could be to 95 per cent, according to the International Institute of Tropical Agriculture (IITA). CMD is spread throughout Africa, while CBSD previously known to be a low altitude.
Ugandan cassava brown streak virus (UCBSV) and Cassava brown streak virus (CBSV) (Potyviridae: Ipomovirus) are causal agents of cassava brown streak disease (CBSD), a disease of cassava that presents a significant threat to the food security of East and Central Africa. The disease affects all parts of cassava, but notably the storage roots, making them unsuitable for consumption (Fig. 1.

However, production of cassava is significantly hampered by Cassava Brown Streak Virus (CBSV) and Ugandan cassava brown streak virus (UCBSV), which have devasted yields in the East African region.
A diet of cassava, Irish potatoes and indigenous vegetables helped Uganda’s President Yoweri Museveni shed 30kg (4 stone), he told the BBC. “I am always fit but the doctors pointed out the.
Annual demand of cassava and cassava derived products in Uganda stood at 2.85 million MT (fresh root equivalent) in 2014 and is expected to increase by 31% in 2020. The deficit is expected to grow to over 900,000 MT (fresh root equivalent) due to population growth if production constraints of disease are not fully addressed. The major players in cassava and cassava product marketing in Uganda.
