In vitro Production of Virus-Free Sweet Potato [Ipomoea batatas (L.) Lam] by Meristem Culture and Thermotherapy

Viral disease is the major factor causing significant yield loss in sweet potato. Production of disease-free clones by tissue culture technique increases yield and income of farmers. Meristems from three varieties of sweet potato were cultured at different combinations of BAP, GA3 and NAA in MS basal medium. Among the combinations, 1 mg/l BAP and 1 mg/l GA3 with 0.01 mg/l NAA resulted in 66.67% shoot induction for Awassa-83 and Guntute while 63.33% shoot induction was obtained using 1 mg/l BAP, 2 mg/l GA3 and 0.01 mg/l NAA for Awassa local. There was 100% sweet potato virus elimination from all the three varieties by meristem culture as observed by using NCM-ELISA technique. Shoot thermotherapy was done for Awassa-83 and Awassa local at 37°C for 31 days and 88.89% and 100% SPFMV and SPCSV virus elimination was achieved for the two varieties, respectively. Best shoot multiplication was obtained in MS medium containing 2 mg/l BAP for Awassa-83 (5.26 ± 0.02 shoots/explant) and Awassa local (5.12 ± 0.02 shoots/explant). For Guntute it was 2.48 ± 0.03 shoots/explant on 3 mg/l BAP. The best root length was 9.5 ± 0.10 cm, 9.68 ± 0.02 cm, and 11.03 ± 0.02 cm for Awassa-83, Awassa local and Guntute, respectively on growth regulators free ½ MS medium. The highest number of roots per shoot (6.34 ± 0.01) was obtained from Awassa-83 on 0.1 mg/l IBA. Acclimatizations were 100%, 91.11% and 90.10% for Guntute, Awassa-83 and Awassa local, respectively. This work indicates the practical applicability of plant tissue culture using meristem culture and thermotherapy to produce virus-free planting materials of sweet potato

Genome-wide association mapping for grain shape and color traits in Ethiopian durum wheat (Triticum turgidum ssp. durum)

Grain shape and color strongly influence yield and quality of durum wheat. Identifying QTL for these traits is essential for transferring favorable alleles based on selection strategies and breeding objectives. In the present study, 192 Ethiopian durum wheat accessions comprising 167 landraces and 25 cultivars were genotyped with a high-density Illumina iSelect 90K single-nucleotide polymorphism (SNP) wheat array to conduct a genome-wide association analysis for grain width (GW), grain length (GL), CIE (Commission Internationale l'Eclairage) L* (brightness), CIE a* (redness), and CIE b* (yellowness) traits. The accessions were planted at Sinana Agricultural Research Center, Ethiopia in the 2015/2016 cropping season in a complete randomized block design with three replications. Twenty homogeneous and healthy seeds per replicate were used for trait measurement. Digital image analysis of seeds with GrainScan software package was used to generate the phenotypic data. Analysis of variance revealed highly significant differences between accessions for all traits. A total of 46 quantitative trait loci (QTL) were identified for all traits across all chromosomes. One novel major candidate QTL (−lg P ≥ 4) with pleiotropic effects for grain CIE L* (brightness) and CIE a* (redness) was identified on the long arm of chromosome 2A. Eighteen nominal QTL (−lg P ≥ 3) and 26 suggestive QTL (−lg P ≥ 2.5) were identified. Pleiotropic QTL influencing both grain shape and color were identified

Coverage of child health services in rural districts of Ethiopia with the health services extension program

Improving access to health care services has been advocated widely since the Declaration of Alma-Ata. Despite the efforts to realize this in Ethiopia, it is only in the year 2003 that the intention to take the package of essential health services to the kebele level (smallest administrative unit) was realized through the introduction of the Health Services Extension Program (HSEP). The objective of this study was to explore whether introduction of HSEP has improved the coverage of child health services in the rural areas of Jimma Zone. A cross sectional study was conducted in three randomly selected districts of Jimma Zone, Southwest Ethiopia. The data collection was undertaken during the months of May, June and July, 2009. A structured questionnaire was used to interview female heads of sampled households from nine kebeles randomly selected in three Woredas (districts). Data were collected on the socio-demographic characteristics, use of health posts, child vaccination and childhood diarrhea. Checklists were used for record review. Data obtained were analysed using statistical package for social sciences (SPSS) V14. Only 64.0% of the kebeles had functional health posts, although another 32.0% of the kebeles in the zone had health posts under construction. However, most (93.7%) of the kebeles in the zone already had two health extension workers (HEWs) assigned. Vaccination coverage as measured by DPT3 was 67.9%, and 10% of the under-two year old children included in this survey had diarrhoea during the past two weeks. Of the 34 (51.5%) mothers who sought help during diarrhoeal attacks, 12 (35.3%) of them went to the health post. The first places of treatment seeking were health centres and health posts, with equal proportion for both (43.5%). Treatment was sought within a day or two after commencement of diarrhoea for 70.6% of the children. Thirty nine (69.7%) of the 56 children who were given recommended fluids received oral rehydration solution (ORS) or homemade solution. In addition to continuing efforts to improve coverage, there is a need to ensure that activities are linked with follow up of vaccination, early treatment seeking and proper home management of diarrhoea

However, the risk factors for ART discontinuation are poorly understood in developing countries particularly in Ethiopia. This review aimed to assess the best available evidence regarding risk factors for ART discontinuation in Ethiopia. Methods Quantitative studies conducted in Ethiopia between 2002 and 2015 that evaluated factors associated with ART discontinuation were sought across six major databases. Only English language articles were included. This review considered studies that included the following outcome: ART treatment discontinuation, i.e. ‘lost to follow up’, ‘defaulting’ and ‘stopping medication’. Meta- analysis was performed with Mantel Haenszel method using Revman-5 software. Summary statistics were expressed as pooled odds ratio with 95% confidence intervals at a p-value of <0.05. Results Nine (9) studies met the criteria of the search. Five (5) were retrospective studies, 3 were case control studies, and 1 was a prospective cohort study. The total sample size in the included studies was 62,156. Being rural dweller (OR = 2.1, 95%CI: 1.5–2.7, I2 = 60%), being illiterate (OR = 1.5, 95%CI: 1.1–2.1), being not married (OR = 1.4, 95%CI: 1.1–1.8), being alcohol drinker (OR = 2.9, 95%CI: 1.9–4.4, I2 = 39%), being tobacco smoker (OR = 2.6, 95%CI: 1.6–4.3, I2 = 74%), having mental illness (OR = 2.7, 95%CI: 1.6–4.6, I2 = 0%) and being bed ridden functional status (OR = 2.3, 95%CI: 1.5–3.4, I2 = 37%) were risk factors for ART discontinuation. Whereas, having HIV positive partner (OR = 0.4, 95%CI: 0.3–0.6, I2 = 69%) and being co-infected with Tb/HIV (OR = 0.6, 95%CI: 0.4–0.9, I2 = 0%) were protective factors. Conclusion Demographic, behavioral and clinical factors influenced ART treatment discontinuation. Hence, we recommend strengthening decentralization of HIV care services in remote areas, strengthening of ART task shifting, application of seek-test-treat-succeed model, and integration of smoking cession strategies and mental health care into the routine HIV care program

Genome-wide association analysis unveils novel QTLs for seminal root system architecture traits in Ethiopian durum wheat

Background: Genetic improvement of root system architecture is essential to improve water and nutrient use efficiency of crops or to boost their productivity under stress or non-optimal soil conditions. One hundred ninety-two Ethiopian durum wheat accessions comprising 167 historical landraces and 25 modern cultivars were assembled for GWAS analysis to identify QTLs for root system architecture (RSA) traits and genotyped with a high-density 90 K wheat SNP array by Illumina. Results: Using a non-roll, paper-based root phenotyping platform, a total of 2880 seedlings and 14,947 seminal roots were measured at the three-leaf stage to collect data for total root length (TRL), total root number (TRN), root growth angle (RGA), average root length (ARL), bulk root dry weight (RDW), individual root dry weight (IRW), bulk shoot dry weight (SDW), presence of six seminal roots per seedling (RT6) and root shoot ratio (RSR). Analysis of variance revealed highly significant differences between accessions for all RSA traits. Four major (− log10P ≥ 4) and 34 nominal (− log10P ≥ 3) QTLs were identified and grouped in 16 RSA QTL clusters across chromosomes. A higher number of significant RSA QTL were identified on chromosome 4B particularly for root vigor traits (root length, number and/or weight). Conclusions: After projecting the identified QTLs on to a high-density tetraploid consensus map along with previously reported RSA QTL in both durum and bread wheat, fourteen nominal QTLs were found to be novel and could potentially be used to tailor RSA in elite lines. The major RGA QTLs on chromosome 6AL detected in the current study and reported in previous studies is a good candidate for cloning the causative underlining sequence and identifying the beneficial haplotypes able to positively affect yield under water- or nutrient-limited conditions

Videovoice diaries to understand the perspectives of community health volunteers in Ethiopia: insights from collaborative qualitative research

Background: Audio-visual diary to collect data on daily routines of study participants is relatively new in health systems research. The concept uses participatory research techniques to elicit participants' views, priorities and empower them to take action. Methods: We discuss a collaborative qualitative study conducted by university researchers, rural communities and health managers (Southwest Ethiopia). We used Videovoice to understand the role of community health volunteers as mediators of accessible and responsive Primary Health Care in Ethiopia. Footage is obtained from 30 Health Development Army leaders in 3 diverse districts, over 3–4 months. Following community engagement and training, participants received an encrypted phone with recording capability. They are supported by researchers through regular contacts, to establish trust, support, and reduce social desirability. A co-production workshop with participants and researchers to interpret the findings will be held. Results: Employing Videovoice diaries demonstrates that collaborations involving academic researchers, community members and volunteers (as lay researchers) and managers have considerable benefits as well as challenges. Videovoice shifts power to the participants: they determine what to capture, what is important and how to convey their views and activities. Data is enriched by participant-generated insights into the reasons behind their decisions. Intensive engagement, effective communication and trust are essential in understanding constraints and preferences of their role, and interpreting findings. A multi-disciplinary research team will enhance the analytical process. Discussion: Videovoice can be a useful tool in enabling lay researchers to describe their daily life, better understand their needs, and identify mechanisms for change. The approach can strengthen the immediacy of the research, capturing perceptions within context. Co-production will involve a significant shift in power and emergence of new directions

Molecular evaluation of Ethiopian sweet sorghum germplasm and their contribution to regional breeding programs

Sweet sorghum is an excellent feedstock for ethanol production and is also used for food and livestock feed. Germplasm collection and characterization in sweet sorghum is a crucial step towards breeding and development of superior genotypes for various end-uses. In the present study, 13 Simple Sequence Repeat (SSR) markers were used for genotyping 175 Ethiopian sweet sorghum genotypes alongside 27 improved accessions from eastern and southern Africa. All the tested markers detected 159 alleles and a high degree of polymorphism information content (PIC) averaging 0.69. A comparison between Ethiopian and improved accessions revealed higher allele numbers (124) in Ethiopian than improved accessions (92 alleles). More than half (65 out of 124) of the alleles observed in the Ethiopian accessions were rare (<5%) and 64 were private (only present within Ethiopian accessions) while in the improved accessions, 41% and 38% of the alleles detected were rare and private respectively. Both weighted Neighbor Joining-based clustering and hierarchical clustering grouped the 202 accessions into three major clusters based on geographical origin. Ethiopian accessions from the north (north Wello and south Tigray) not only clustered separately from accessions from the west central and eastern Ethiopia, but were also distinct from most of the improved genotypes. Our results reveal an unexploited highly diverse sweet sorghum genetic resource from Ethiopia that can be included in the regional breeding programs in order to efficiently optimize productivity
