BACKGROUNDMost GWAS of plasma proteomics have focused on White individuals of European ancestry, limiting biological insight from other ancestry-enriched protein quantitative loci (pQTL).METHODSWe conducted a discovery GWAS of approximately 3,000 plasma proteins measured by the antibody-based Olink platform in 1,054 Black adults from the Jackson Heart Study (JHS) and validated our findings in the Multi-Ethnic Study of Atherosclerosis (MESA). The genetic architecture of identified pQTLs was further explored through fine mapping and admixture association analysis.

- Circulating metabolite levels are indicators of human health and can be influenced by genetic factors; however, most research has focused on European populations.
- The study utilized metabolomics data from 25,058 diverse individuals, identifying 1,778 gene loci linked to 667 metabolites and providing methods for data analysis and handling.
- Notably, the research uncovered new genetic associations, including 108 novel gene-metabolite pairs, and highlighted sex differences in metabolism, enhancing the understanding of genetic influences on human health.
Premise: Because of its broad range in the neotropical rainforest and within tree canopies, the tank bromeliad Guzmania monostachia was investigated as a model of how varying leaf hydraulic conductance (K ) could help plants resist and recover from episodic drought. The two pathways of K , inside and outside the xylem, were also examined to determine the sites and causes of major hydraulic resistances within the leaf.
Methods: We measured leaf hydraulic conductance for plants in the field and laboratory under wet, dry, and rewetted conditions and applied physiological, anatomical, and gene expression analysis with modeling to investigate changes in K .
