ABSTRACT

KEY MESSAGE: Genomic analysis of Mediterranean oats reveals high genetic diversity and three loci for adaptation to this environment. This information together with phenotyping and passport data, gathered in an interactive map, will be a vital resource for oat genetic improvement. During the twentieth century, oat landraces have increasingly been replaced by modern cultivars, resulting in loss of genetic diversity. However, landraces have considerable potential to improve disease and abiotic stress tolerance and may outperform cultivars under low input systems. In this work, we assembled a panel of 669 oat landraces from Mediterranean rim and 40 cultivated oat varieties and performed the first large-scale population genetic analysis of both red and white oat types of Mediterranean origin. We created a public database associated with an interactive map to visualize information for each accession. The oat collection was genotyped with 17,288 single-nucleotide polymorphism (SNP) loci to evaluate population structure and linkage disequilibrium (LD); to perform a genome-wide association study (GWAs) for heading date, a key character closely correlated with performance in this drought-prone area. Population genetic analysis using both structure and PCA distinguished two main groups composed of the red and white oats, respectively. The white oat group was further divided into two subgroups. LD decay was slower within white lines in linkage groups Mrg01, 02, 04, 12, 13, 15, 23, 33, whereas it was slower within red lines in Mrg03, 05, 06, 11, 21, 24, and 28. Association analysis showed several significant markers associated with heading date on linkage group Mrg13 in white oats and on Mrg01 and Mrg08 in red oats.

ABSTRACT

Zoonotic diseases require a One Health approach for successful control and elimination due to the nature of their transmission between animals and humans. One Health recognises that the health of humans, animals, and the environment are all interconnected. Ethiopia has committed itself to controlling five prioritised zoonotic diseases (rabies, anthrax, brucellosis, leptospirosis and echinococcosis), using a One Health approach. The National One Health Steering Committee (NOHSC) provides a framework for national stakeholders to address gaps in multisectoral communication, coordination and collaboration. In addition, the NOHSC oversees the formation of several specialised disease-focused groups, referred to as 'Technical Working Groups' (TWGs). These TWGs are responsible for developing disease prevention and control strategies, as well as implementing disease-focused public health activities and providing recommendations to the NOHSC. Ethiopia's success using the One Health approach and its efficient control of zoonotic diseases will depend on the commitment of all member Ministries to support the NOHSC and TWGs, as well as to build capacity in Ethiopia's workforce and laboratories, a task supported by its many international partners.


Les zoonoses étant par nature des maladies transmissibles entre les animaux et l'homme, l'approche Une seule santé est la seule qui permette de les contrôler efficacement en vue de les éliminer. Le concept Une seule santé repose sur la prise en compte de l'interconnexion entre la santé humaine, celle des animaux et celle de l'environnement. L'Éthiopie s'est fixé pour objectif de lutter contre cinq maladies zoonotiques classées comme prioritaires (rage, fièvre charbonneuse, brucellose, leptospirose et échinococcose) en suivant une approche Une seule santé. Le comité de pilotage national Une seule santé (NOHSC) apporte un cadre permettant aux parties prenantes du pays de résoudre les problèmes de communication, de coordination et de collaboration intersectorielles. En outre, le NOHSC supervise la création de plusieurs groupes de travail techniques dédiés à des maladies spécifiques. Ces groupes de travail sont chargés d'élaborer des stratégies de prévention et de contrôle, de mettre en oeuvre des activités de santé publique axées sur ces maladies et de formuler des recommandations à l'intention du NOHSC. La réussite des efforts déployés par l'Éthiopie pour appliquer les principes Une seule santé et l'efficacité de la lutte contre les maladies zoonotiques dépendront de l'engagement des ministères concernés à soutenir le NOHSC et les groupes de travail techniques et à renforcer les capacités des ressources humaines et des laboratoires éthiopiens, tâche qui bénéficie de l'appui de nombreux partenaires internationaux.


Toda labor eficaz de control y eliminación de las enfermedades zoonóticas, por la propia naturaleza de su transmisión entre animales y personas, pasa por abordar estas patologías desde los planteamientos de Una sola salud, noción esta que parte del reconocimiento de que salud humana, animal y ambiental están siempre interconectadas. Etiopía está embarcada en el innegociable empeño de combatir cinco enfermedades zoonóticas consideradas prioritarias (rabia, carbunco bacteridiano, brucelosis, leptospirosis y equinococosis) trabajando desde la óptica de Una sola salud. El Comité Directivo Nacional de Una sola salud proporciona a los interlocutores del país un marco de referencia que sirve para subsanar las lagunas existentes en cuanto a comunicación, coordinación y colaboración entre los diversos sectores. Ese órgano, además, supervisa la formación de varios grupos especializados y centrados en una u otra enfermedad, denominados grupos de trabajo técnicos, que tienen por cometido elaborar estrategias de prevención y control de una enfermedad concreta, llevar adelante acciones de salud pública dirigidas contra ella y formular recomendaciones para el Comité Directivo. El éxito de Etiopía a la hora de aplicar los postulados de Una sola salud y de combatir eficazmente las enfermedades zoonóticas dependerá del nivel de compromiso con que todos los ministerios copartícipes presten apoyo al Comité Directivo y los grupos de trabajo técnicos y ayuden a instaurar en el país un tejido lo bastante solvente de laboratorios y recursos humanos, empresa esta en la que Etiopía cuenta con el respaldo de sus numerosos asociados internacionales.

ABSTRACT

Bone marrow transplantation has been employed with increasing frequency for patients with a variety of malignant disorders. Autologous bone marrow rescue (ABMR) is one of the most exciting and promising areas in clinical oncology.
