Cassava mosaic disease (CMD) is a major constraint to sustainable production of cassava (Manihot esculenta Crantz) in Zambia and other sub-Saharan African countries. During a survey conducted between April and May 2014 in six (Western, Northwestern, Northern, Luapula, Lusaka, and Eastern) provinces of Zambia, 226 symptomatic cassava leaf tissue samples were collected from CMD-affected plants in 214 farmers fields. PCR screening of these samples using species-specific primers targeting multiple cassava mosaic geminiviruses (Aloyce et al. 2013) revealed the presence of African cassava mosaic virus (ACMV), East African cassava mosaic virus (EACMV), and East African cassava mosaic Malawi virus (EACMMV) in the samples as single or mixed infections of different proportions. Considering that EACMMV is a previously unreported virus from Zambia, DNA extracts from three samples (ZM-LSK48 from Lusaka Province, ZM-E74 from Eastern province, and ZM-N112 from Northern province) showing severe symptoms of ...

Cassava brown streak disease (CBSD) has a viral aetiology and is caused by viruses belonging to the genus Ipomovirus (family Potyviridae), Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV). Molecular and serological methods are available for detection, discrimination and quantification of cassava brown streak viruses (CBSVs) in infected plants. However, precise determination of the viral RNA localization in infected host tissues is still not possible pending appropriate methods. We have developed an in situ hybridization (ISH) assay based on RNAscope® technology that allows the sensitive detection and localization of CBSV RNA in plant tissues. The method was initially developed in the experimental host Nicotiana rustica and was then further adapted to cassava. Highly sensitive and specific detection of CBSV RNA was achieved without background and hybridization signals in sections prepared from non-infected tissues. The tissue tropism of CBSV RNAs appeared different

Cassava (Manihot esculenta Crantz) is a starchy root crop grown in the tropics mainly by small-scale farmers even though agro-industrial processing is rapidly increasing. For this processing market improved varieties with high dry matter root content (DMC) is required. Potentially toxic cyanogenic glucosides are synthesized in the leaves and translocated to the roots. Selection for varieties with low cyanogenic glucoside potential (CNP) and high DMC is among the principal objectives in cassava breeding programs. However, these traits are highly influenced by the environmental conditions and the genetic control of these traits is not well understood. An S(1) population derived from a cross between two bred cassava varieties (MCOL 1684 and Rayong 1) that differ in CNP and DMC was used to study the heritability and genetic basis of these traits. A broad-sense heritability of 0.43 and 0.42 was found for CNP and DMC, respectively. The moderate heritabilities for DMC and CNP indicate that the ...
We used 13 microsatellite marker loci to determine the genetic diversity of cassava (Manihot esculenta Crantz) grown in home gardens in two Chibchan Amerindian reserves in Costa Rica. We compared the levels of genetic diversity in the reserves with that of commercial varieties typically cultivated in Costa Rica. We found high levels of genetic diversity among cassava plants. Overall, 12 of the 13 loci examined were polymorphic in each Amerindian reserve (P = 92.3). Moreover, we found 36 alleles in the Coto Brus Reserve and 33 in the Talamanca Reserve. In the commercial varieties only nine loci were polymorphic (P = 69.2), and we only found 23 alleles. Heterozygosity was high for all groups of cassava (Coto Brus, Talamanca, and commercial varieties), but it was higher among the commercial varieties. The levels of heterozygosity and allele diversity indicate that there is significant genetic diversity in the home gardens that we examined. Another indication of the high diversity found in these ...
The cassava was modified for resistance to Cassava mosaic disease (CMD) by introducing an RNA interference cassette that targets African cassava mosaic virus (ACMV) replication associated disease AC1. The production of hairpin RNA by the host cells trigger an RNAi response that is expected to target viral transcripts and prevent viral replication and thus further infection. Due to conservation between AC1 sequences in ACMV and East african cassava mosaic virus, the modified cassava is expected to resistant to both viruses, which are the causal agents of CMD. A selectable marker, Escherichia coli hygromycin B phosphotransferase, was additionally included for hygromycin selection during transformation ...
Cassava production in Africa is compromised by cassava brown streak disease (CBSD) and cassava mosaic disease (CMD). To reduce costs and increase the precision of resistance breeding, a QTL study was conducted to identify molecular markers linked to resistance against these diseases. A bi-parental F1 mapping population was developed from a cross between the Tanzanian farmer varieties, Namikonga and Albert. A one-step genetic linkage map comprising 943 SNP markers and 18 linkage groups spanning 1776.2 cM was generated. Phenotypic data from 240 F1 progeny were obtained from two disease hotspots in Tanzania, over two successive seasons, 2013 and 2014. Two consistent QTLs linked to resistance to CBSD-induced root necrosis were identified in Namikonga on chromosomes II (qCBSDRNFc2Nm) and XI (qCBSDRNc11Nm) and a putative QTL on chromosome XVIII (qCBSDRNc18Nm). qCBSDRNFc2Nm was identified at Naliendele in both seasons. The same QTL was also associated with CBSD foliar resistance. qCBSDRNc11Nm was ...
Thermotherapy was used to free three cassava (Manihot esculenta) cultivars of African cassava mosaic, an important viruslike disease of cassava in East Africa. The pathogen was eradicated from 33 44% of tip cuttings (1.0 1.5 cm long) after hot-air treatment of mother plants at 37 C for 87 105 days. Survival of these tip cuttings after 35 105 days ranged from 22 73%. Exposure of entire cassava plants to hot-air treatments at 37 C for 42 96 days caused temporary remission of symptoms in most plants. Only one of 129 surviving plants was freed of disease. Two successive hot-water treatments of diseased stem cuttings at 50 or 55 C for varying intervals were not therapeutic. Keyword(s): ...
Cassava (Manihot esculenta Crantz) and the viruses that infect it, notably cassava mosaic virus and cassava brown streak viruses, have a unique history of co-evolution and co-existence. While cassava originated in South America, both viruses and the diseases they cause have largely been limited to the East African region, where they have, and continue to be key yield-robbing stresses. For sustainable control, we assume that deployment of resistant varieties when carefully combined with phytosanitation will combat these viruses. We have thus generated empirical data and tested the limits, i.e., how long this strategy can last. This entailed the comparison of elite cassava varieties, one set of virus-indexed tissue culture plantlets, and the other set, re-cycled planting materials under farmers cyclic propagation for 6-23 years. Trials were established at diverse sites in Uganda. We observed that both officially-released and unofficially-released cassava varieties are common in farmers fields; ...

OSORIO, Mayra; GAMEZ, Elizabeth; MOLINA, Sandy and INFANTE, Diógenes. Evaluation of cassava plants generated by somatic embryogenesis at different stages of development using molecular markers. Electron. J. Biotechnol. [online]. 2012, vol.15, n.4, pp.3-3. ISSN 0717-3458.. Background: Cassava (Manihot esculenta Crantz) is a crop that is high in carbohydrates in the roots and in protein in the leaves, important for both human consumption and animal feed, and also has a significant industrial use for its starches. In this study we evaluated the genetic variability with molecular markers in different stages in micropropagated plants from somatic embryos of Venezuelan native clone 56. Results: Three markers were used: ISTR, AFLP and SSR, finding that ISTR showed the highest polymorphism among individuals tested. With AFLP a high similarity between the evaluated individuals was observed and with SSR total monomorphism was seen. Using cluster analysis it was found that individuals from an embryo ...
Changes in acidification and starch behaviour were investigated during co-fermentation of cassava and soybean into gari, an African fermented product. Non-volatile acidity, pH and starch content were evaluated using standard analytical methods. Starch breakdown and pasting characteristics were also analysed using a Brabender viscoamylograph. Fermentation caused significant variations in the pH, non-volatile acidity and starch concentration. The pH decreased with concomitant increases in non-volatile acidity during co-fermentation of the cassava dough. Soy fortification up to 20% caused only minimal effects on the pH, titratable acidity and starch content during the fermentation period. Starch content decreased from 69.8% to 60.4% within the 48 h fermentation time in the unfortified sample, with similar trends noted at all levels of fortification. Starch pasting characteristics showed varied trends in pasting temperature, peak viscosity, viscosity at 95_C and at 50_C-hold with increasing ...
Cassava is an important tuber crop grown mainly in the tropical and sub-tropical regions. The crop is a source of calories for over 500 million people worldwide. To improve the crop, genetic improvement through breeding is necessary. The use of simple sequence repeat (SSR) and single nucleotide polymorphism (SNP) are the powerful tools to generate a linkage map in cassava. F1 mapping population from 96 1089A and TME 117 was developed with 180 progenies. To produce the linkage map, parental lines were screened with over 200 SSR markers and the polymorphic markers were used on the progenies. Of 717 SNP markers used, 347 were polymorphic. 253 markers comprising of 248 SNP and 5 SSR markers were used. 18 linkage groups were drawn with an average of 14 markers on each chromosome and the average marker distance of 6.5cM. The total length of the map was 1,493cM. SNP markers are many and could be easily used to construct a genetic linkage map compared with SSR markers.. ...

ABSTRACT: Cassava (Manihot esculenta Crantz) roots spoil 2 to 3 d after harvest because of postharvest physiological deterioration (PPD), which has remained an unsolved problem. Roots from different sources of germplasm were evaluated 5, 10, 20, and 40 d after harvest and some were found to be tolerant to PPD. Three genotypes showed zero levels of PPD even 40 d after harvest. Tolerance to PPD in roots with high carotenoid levels may be explained by their anti- oxidant properties. Irradiation of seeds in mutagenized populations may have silenced one of the genes involved in the expression of PPD. The tolerance to PPD found in other sources cannot be properly explained. The identification of several sources of resistance (and at least two different modes of action) suggests that now there are alternatives available for solving this problem, benefiting millions of resource- limited farmers worldwide.
Scientists have now shed more light on how a farmers variety in Tanzania is able to tolerate the deadly viral Cassava Brown Streak Disease (CBSD) disease after infection, showing limited symptoms and impact on yield. The team have established that Namikonga plants have a complex line of defense involving many biochemical pathways and genes that…. ...

A project with the potential to improve cassava breeding programs in Rwanda and elsewhere. The mechanisms underlying the development of root necrosis in cassava infected with cassava brown streak viruses are not currently understood. Root necrosis is the symptom responsible for the majority of marketable and edible cassava yield losses. Better understanding will have a major impact upon cassava breeding programs in Rwanda and many other countries in Sub-Saharan Africa.. This project seeks to explore whether cassava varieties that do not show root disease symptoms actually contain the virus and are resistant to necrosis, or whether these varieties are able to restrict virus movement to their roots. Specifically the project will investigate whether there is a link between virus concentration and root necrosis symptoms in cassava roots affected by Cassava Brown Streak Disease (CBSD) in Rwanda. This will improve understanding of why some CBSD-affected cassava varieties show high virus concentrations ...
When you start talking about food security, you have to have to think about disease detection and management. Thats what Im thinking about as I get ready to leave for a cassava field survey in southern Tanzania.. You might know cassava (Manihot esculenta Crantz) as tapioca, or a thickener in pies and bubble tea. But for over 800 million people in Africa and Asia this crop of tubers is their main source of food and income.. For example, according to the UNs Food and Agriculture Organization, as of the late 1990s, cassava roots were the single largest source of calories for 40 percent of the population in Africa.. In sub-Saharan Africa, cassava is grown by smallholder farmers, many of whom are women. It is estimated that cassava consumption in that region amounts to approximately 80 kilograms per person per year, making cassava their most important staple crop. Cassava is drought resistant, grows in poor soil, and can be stored for long periods underground. It is often the only crop to survive ...
This report corresponds to Phase 2 (pilot project) of an Integrated Cassava Project whose general objective is the creation of a rural agroindustry that produces cassava flour for human consumption. In Phase 1 (Research), the main objective was to determine the technical and economical conditions required for the development of a rural cassava flour agroindustry. In summary, the process designed has the following steps: selection and preparation of cassava roots, mechanical washing, chipping, artificial drying, premilling, milling, sieving, and packaging. The second phase sought to integrate the production, processing and marketing components of the cassava flour system under the real socioeconomic conditions at Chinú, a cassava-growing region of the Córdoba department in the Atlantic coast of Colombia. As the project conclusion, the feasibility study of the cassava flour agroindustry considers the following four areas: technical feasibility (the process), commercial feasibility (the market), ...

Cassava (Manihot esculenta Crantz) is a major tropical crop. Regarded as an orphan crop a few decades ago, it now receives considerable attention from governments, industry and agencies investing in agricultural research. As a result, the cassava community generates vast amounts of information and develops useful technologies and products. This positions cassava as a key industrial commodity and a reliable food security staple. Significant genetic gains have been achieved through the early 2000s. Gains are particularly noticeable under better agronomic conditions, as was the case for the green revolution of cereals. However, further gains obtained in the past two decades have not been as impressive. Cassava breeding cycle is long, and its multiplication rate slow. Therefore, it takes no less than 8 years to develop a new variety. Cassava breeding is based on the use of heterozygous progenitors which has important drawbacks. One of them is the impossibility to implement conventional back-crossing.

Manihot esculenta, commonly known as bitter cassava, tapioca, manioc or yuca, is a milky-sapped tropical shrub that grows to 6-10 tall. Although native to Brazil, it has been planted as an annual root crop in tropical areas around the world for harvest of its stout, elongated, tuberous roots from which cassava, tapioca, starch and other food products are obtained. It features palmately lobed, medium green leaves (typically 3-7 parted) with each leaf lobe growing to 3-8" long. Small, apetulous, greenish-white flowers (corolla is absent but bell-shaped calyx is petal-like) in short terminal panicles bloom throughout the year. Flowers are unisexual. Fruit is an ovoid 6-winged capsule. Roots contain toxic hydrocyanic acid which must be removed prior to consumption. Cultivated varieties are classed into two different groups: bitter varieties (primarily grown for starch) and sweet varieties (primarily grown as vegetable). Species plants and unvariegated varieties have little to no ornamental value ...
Cassava is the third largest source of carbohydrates for human food in the world but is vulnerable to virus diseases, which threaten to destabilize food security in sub-Saharan Africa. Novel methods of cassava disease detection are needed to support improved control which will prevent this crisis. Image recognition offers both a cost effective and scalable technology for disease detection. New deep learning models offer an avenue for this technology to be easily deployed on mobile devices. Using a dataset of cassava disease images taken in the field in Tanzania, we applied transfer learning to train a deep convolutional neural network to identify three diseases and two types of pest damage (or lack thereof). The best trained model accuracies were 98% for brown leaf spot (BLS), 96% for red mite damage (RMD), 95% for green mite damage (GMD), 98% for cassava brown streak disease (CBSD), and 96% for cassava mosaic disease (CMD). The best model achieved an overall accuracy of 93% for data not used in the
In plant genetic engineering, the identification of gene promoters leading to particular expression patterns is crucial for the development of new genetically modified plant generations. This research was conducted in order to isolate and characterize several new promoters from cassava (Manihot esculenta Crantz) elongation factor 1 alpha (EF1A) gene family. Three promoters MeEF1A3, MeEF1A4 and MeEF1A5 were successfully isolated. Sequence analyses showed that all of the promoters contain three conserved putative cis-acting elements which are located upstream of the transcription start site. These elements are included a TEF1, a TELO and TATA boxes. In addition, all of the promoters also have the 5′UTR intron but with a different lengths. These promoters were constructed translationally with gusAreporter gene (promoter::gusA fusion) in pBI-121 binary vector to build a new binary vector using Overlap Extension PCR Cloning (OEPC) technique. Transient expression assay that was done by using ...
Oct 2012 Although cassava is an important food security crop, it has been threatened first by the outbreak of Cassava Mosaic Diseases (CMD) and lately Cassava Brown Streak Disease (CBSD). With funding support from the European Union (EU), European Commission (EC) and ECHO, FAO has implemented projects in Uganda that have aimed at first, mitigating the spread of the disease by multiplying and distributing disease free varieties and secondly by coordinating all efforts in the country and region.. ...
Warning: This plant is poisonous, producing a toxin called cycasin that affects the gastrointestinal tract and nervous system. Itis known in Honduras as "yuca de ratón", meaning mouse manioc and referring to their use as a rodenticide. The allusion is to Manihot esculenta Crantz (Euphorbiaceae), a poisonous tuber with high starchy ontent made edible through a process similar to that used for zamias. The Pech indigenous group call Z. standleyi, yojni unicej ("venomous yuca"). Its root is highly poisonous, and has been employed at times for criminal poisonings, as well as for poisoning noxious animals. There is a popular belief that the root, if out of the ground two days, kills its human victim in two days; if dug in a week, it kills in a week, and so on. Poisonous Parts: Fleshy seeds, stems, roots, leaves. Protect pets and instruct children to never eat or chew any plant material without permission ...
A nutty-flavored, starchy root vegetable, cassava (also known as yuca) is one of the most drought-resistant crops and is a major source of calories and carbs for people in developing countries, serving as the primary food for more than 800 million people. However, the crop is vulnerable to virus diseases, such as cassava brown streak disease (CBSD), which poses the biggest threat to production in East and Central Africa. CBSD typically spreads through the whitefly vector (Bemisia tabaci) or the common practice of using recycled stems from the previous seasons crop. Although the planting of clean seed would be an effective way for farmers to reduce CBSD, the seed is often not available and when it is available, it is too expensive. Instead, farmers use recycled planting materials which is sometimes infected with cassava brown streak ipomoviruses. To understand how cassava virus disease builds up over repeated planting cycles, a team of Tanzania-based scientists conducted experiments in coastal ...
One of the worst diseases of the tuber crop, cassava, in sub-Saharan Africa is Cassava brown streak disease (CBSD).

Cassava production is a very attractive option for smallholders, many of whom have relatively few other options for raising income and linking effectively to markets. For this reason, governments and development agencies should be increasing their interest in cassava as a potential pathway out of poverty for many rural poor. However production uncertainties and constraints have combined with expectations of strong global demand to sustain reasonably high prices for cassava and cassava products. In addition the recent establishment of several exotic pests and diseases in the region is broadly identified as the most important threat to its continued production. To maintain the attractiveness of cassava as a feedstock for a range of processing industries, cassava production must be highly cost-effective and more environmentally friendly so as to allay concerns about land degradation. CIAT is one of the 15 International Agriculture Research Centers under the Consultative Group for International ...
Under attack by herbivores, plants produce a blend of "herbivore-induced plant volatiles (HIPV)" that help natural enemies of herbivores locating their prey, thereby helping plants to reduce damage from herbivory. The amount of HIPV emitted by plants increases with herbivore density and is positively correlated with the intensity of the olfactory response of natural enemies. In this study, we determined the effects of density or within-plant distribution of the herbivorous mite Mononychellus tanajoa on movement of the predatory mite Typhlodromalus aripo out of apices of cassava plants. Proportions of T. aripo that migrated out of apex, and distances traveled were significantly higher when M. tanajoa was further away from the apex-i.e. on middle or bottom leaves of cassava plants-than when present on top leaves, or absent from the plant. This supports previous field observations that T. aripo is not a sit-and-wait predator but uses HIPV to search and locate its prey within cassava plant ...

High-resolution mapping of resistance to cassava mosaic geminiviruses in cassava using genotyping-by-sequencing and its implications for breeding. Virus Research. 186:87-96. Interpretive Summary: Cassava mosaic disease (CMD) is the most important viral disease of cassava in Africa and the Indian sub-continent. The cultivated cassava species is protected from CMD by polygenic resistance introgressed from the wild species Manihot glaziovii and a dominant monogenic type of resistance, named CMD2, discovered in African landraces. The ability of the monogenic resistance to confer high levels of resistance in different genetic backgrounds has led recently to its extensive usage in breeding across Africa as well as in Latin America, even though the virus is not present there. Most of the landraces carrying the monogenic resistance are morphologically very similar and come from a geographically restricted ...
TEACHERS and students of Bulileka Sanatan Primary School in Labasa got a shock when a seven-month-old cassava plant bore a 20 kilogram crop.. Students from the school uprooted the plant on Thursday.. Headteacher Narsamma Naidu said they were thrilled to see such a gigantic crop in their yard.. "This is a rare sight and we are really surprised that we have this big crop right here in our school garden," Ms Naidu said.. "I asked the garden teacher to dig up a cassava plant for our morning tea because we decided to have tea with cassava this morning," she said.. Ms Naidu said they would cook some for morning tea and the rest would be shared among the teachers who were interested.. She said the growth of the plant would have to be attributed to soil fertility given the creek that flowed nearby.. She said five students planted the crop in December.. ...

Cyclodextrin glycosyltransferase (CGTase) catalyzes the conversion of starch into non-reducing cyclic sugars, cyclodextrins, which have several industrial applications. This study aimed to establish optimal culture conditions for β-CGTase production by Bacillus sp. SM-02, isolated from soil of cassava industries waste water lake. The optimization was performed by Central Composite Design (CCD) 2, using cassava flour and corn steep liquor as substrates. The maximum production of 1087.9 U mL−1 was obtained with 25.0 g L−1 of cassava flour and 3.5 g L−1 of corn steep after 72 h by submerged fermentation. The enzyme showed optimum activity at pH 5.0 and temperature 55 °C, and maintained thermal stability at 55 °C for 3 h. The enzymatic activity was stimulated in the presence of Mg+2, Ca+2, EDTA, K+, Ba+2 and Na+ and inhibited in the presence of Hg+2, Cu+2, Fe+2 and Zn+2. The results showed that Bacillus sp. SM-02 have good potential for β-CGTase production.
The performance of a new anion exchanger prepared from raw cassava straw (RCS), for the removal of nitrate from aqueous solutions was evaluated in this study. The cassava straw was modified by epichlorohydrin in the presence of pyridine. The influencing factors, adsorption kinetics, and thermodynamics model of nitrate adsorption onto the modified cassava straw (MCS) were studied. The results showed that the zeta potentials of RCS and MCS were -20.5 mV and +37.3 mV, nitrogen contents (N %) of RCS and MCS were 0.43 and 4.96%, respectively. The best nitrate removal results was reached at 0.2 g of adsorbent dosage and pH range of 6.0÷12.0. The modified cassava straw adsorbed nitrate(V) quickly, reaching equilibrium within 30 minutes. The kinetics of nitrate adsorption at different initial concentrations (25, 50 and 75 mg/dm3) all fit a second order reaction. The adsorption rates were controlled by both membrane diffusion and intra-particle diffusion. The adsorption data fit the Freundlich ...
The roots of cassava present high postharvest perishability due to physiological deterioration that develops in wounded tissues usaully within two to three days after harvest at room temperature. The physiological deterioration is characterized by the appearance of blue-black streaks in the root vascular tissue and storage parenchyma, which progresses through the whole length of the root, being the initial cause for the poor acceptability for fresh consumption. This darkening is attributed to reactions involving the enzymes phenylalanine ammonia lyase, polyphenol oxidase and peroxidase. The objective of this work was to evaluate the effects biochemical, physiological and physical phases by the called minimal processing, the use of antioxidants and of packaging on the development of physiological deterioration in cassava roots during a period of preservation, in order to extend the shelf-life of the product, as well as to ensure food safety during the commercialization, distribution and ...
Molecular typing of pathogen populations is an important tool for the development of effective strategies for disease control. Diverse molecular markers have been used to characterize populations of Xanthomonas axonopodis pv. manihotis (Xam), the main bacterial pathogen of cassava. Recently, diversity and population dynamics of Xam in the Colombian Caribbean coast were estimated using AFLPs, where populations were found to be dynamic, diverse and with haplotypes unstable across time. Aiming to examine the current state of pathogen populations located in the Colombian Eastern Plains, we also used AFLP markers and we evaluated the usefulness of Variable Number Tandem Repeats (VNTRs) as new molecular markers for the study of Xam populations. The population analyses showed that AFLP and VNTR provide a detailed and congruent description of Xam populations from the Colombian Eastern Plains. These two typing strategies clearly separated strains from the Colombian Eastern Plains into distinct populations
