Genetic Sharing with Cardiovascular Disease Risk Factors and Diabetes Reveals Novel Bone Mineral Density Loci.

Bone Mineral Density (BMD) is a highly heritable trait, but genome-wide association studies have identified few genetic risk factors. Epidemiological studies suggest associations between BMD and several traits and diseases, but the nature of the suggestive comorbidity is still unknown. We used a novel genetic pleiotropy-informed conditional False Discovery Rate (FDR) method to identify single nucleotide polymorphisms (SNPs) associated with BMD by leveraging cardiovascular disease (CVD) associated disorders and metabolic traits. By conditioning on SNPs associated with the CVD-related phenotypes, type 1 diabetes, type 2 diabetes, systolic blood pressure, diastolic blood pressure, high density lipoprotein, low density lipoprotein, triglycerides and waist hip ratio, we identified 65 novel independent BMD loci (26 with femoral neck BMD and 47 with lumbar spine BMD) at conditional FDR < 0.01. Many of the loci were confirmed in genetic expression studies. Genes validated at the mRNA levels were characteristic for the osteoblast/osteocyte lineage, Wnt signaling pathway and bone metabolism. The results provide new insight into genetic mechanisms of variability in BMD, and a better understanding of the genetic underpinnings of clinical comorbidity

Flood and salinity management in the Mekong Delta, Vietnam

In Be, T. T.; Sinh, B. T.; Miller, F. (Eds.). Challenges to sustainable development in the Mekong Delta: Regional and national policy issues and research needs: Literature analysis. Bangkok, Thailand: The Sustainable Mekong Research Network (Sumernet)The great variation in water flow of the Mekong River drives the productivity of the agro- and aqua-ecological systems of the basin, yet also forms a key constraint to intensive production systems. The Mekong River has special ecological and hydrological characteristics that are important to the riparian countries. Floods in the rainy season and salinity intrusion in the dry season form the two main physical problems for sustainable development of the Vietnam Mekong delta. The high floods, as in the year 2000, caused deep inundation and severe damage to infrastructure and production in the delta. Salinity intrusion, which is caused by sea water flowing inland when not enough fresh water flows to the estuaries, also causes problems for production and human health. However, people in the delta consider these processes to be normal natural phenomena and have generally adapted their lives to their presence. This paper offers an analysis of current state of knowledge of the subject drawn from a broad spectrum of nearly 100 publications. From this, the paper then identifies research gaps on floods and saline intrusion in the Mekong Delta to be undertaken in order to better inform a policy debate and decision-making on water resources management to ensure sustainable development and equitable management in the delta and Mekong Basin as a whole

Identifying new resistance to Cassava Mosaic Disease and validating markers for the CMD2 locus

Open Access Journal; Published online: 30 Aug 2021Cassava (Manihot esculenta Crantz) is a crucial staple crop, and provides carbohydrate energy to more than half a billion people in the tropics. Cassava mosaic disease (CMD) is the most important disease of cassava in Africa. Since Sri Lanka Cassava Mosaic Virus (SLCMV) was first reported in South East Asia in 2015, establishing sustainable solutions to CMD has become a top priority for the cassava program at the International Center for Tropical Agriculture (CIAT) and its partners. In the present study, we screened two populations for CMD resistance: VNM142, 142 clones collected from farms throughout Vietnam, and CIAT102, 102 clones resistant to CMD or mites, which were introduced from CIAT. High broad-sense heritability was observed in all the trials (>0.80). From the population VNM142, eight clones showed high CMD resistance with CMD severity scores less than 2.0. Two resistant clones had the same DNA fingerprinting with the accessions CR63 (PER262 or TAI9) and KM57 (VNM8) in the genebank, respectively. To our knowledge, this is the first report of CMD resistance in the genebank at CIAT. We also used the two populations to validate the CMD markers S12_7926132 and S14_4626854. Both markers explained 51% of the population variance in the segregating population CIAT102, but only 11% in the diverse population VNM142. Thus, we concluded that the two CMD markers could not be used to select for CMD resistance in diverse populations, but could predict the CMD resistance in segregating populations when the susceptible parents do not have resistant marker alleles and the resistance of the CMD2 donors is confirmed
