Journal Article
Joy, E. J., Kumssa, D. B., Broadley, M. R., Watts, M. J., Young, S. D., Chilimba, A. D. C., & Ander, E. L. (2015). Dietary mineral supplies in Malawi: spatial and socioeconomic assessment. BMC Nutrition, 1, Article 42. https://doi.org/10.1186/s40795-015-0036-4

Background
Dietary mineral deficiencies are widespread globally causing a large disease burden. However, estimates of deficiency prevalence are often only available at national scales or for small population sub-groups with limited relevance for pol...

Inter-varietal variation in caesium and strontium uptake by plants: a meta-analysis (2014)
Journal Article

Radiocaesium and radiostrontium enter the foodchain primarily via plant root uptake. Selecting varieties of crop that display low accumulation of these radionuclides has been suggested as an economically and socially acceptable remediation strategy f...

Soil type influences crop mineral composition in Malawi (2014)
Journal Article
Joy, E. J., Broadley, M. R., Young, S. D., Black, C. R., Chilimba, A. D., Ander, E. L., …Watts, M. J. (2015). Soil type influences crop mineral composition in Malawi. Science of the Total Environment, 505, 587-595. https://doi.org/10.1016/j.scitotenv.2014.10.038

© 2014. Food supply and composition data can be combined to estimate micronutrient intakes and deficiency risks among populations. These estimates can be improved by using local crop composition data that can capture environmental influences includin... Read More about Soil type influences crop mineral composition in Malawi.

Genetical and comparative genomics of Brassica under altered Ca supply identifies Arabidopsis Ca-transporter orthologs (2014)
Journal Article
Graham, N. S., Hammond, J. P., Lysenko, A., Mayes, S., Ó Lochlainn, S., Blasco, B., …Broadley, M. R. (in press). Genetical and comparative genomics of Brassica under altered Ca supply identifies Arabidopsis Ca-transporter orthologs. Plant Cell, 26(7),

Although Ca transport in plants is highly complex, the overexpression of vacuolar Ca2+ transporters in crops is a promising new technology to improve dietary Ca supplies through biofortification. Here, we sought to identify novel targets for increasi... Read More about Genetical and comparative genomics of Brassica under altered Ca supply identifies Arabidopsis Ca-transporter orthologs.

Dietary mineral supplies in Africa (2014)
Journal Article
Joy, E. J., Ander, E. L., Young, S. D., Black, C. R., Watts, M. J., Chilimba, A. D., Chilima, B., Siyame, E. W., Kalimbira, A. A., Hurst, R., Fairweather-Tait, S. J., Stein, A. J., Gibson, R. S., White, P. J., & Broadley, M. R. (2014). Dietary mineral supplies in Africa. Physiologia Plantarum, 151(3), 208-229. https://doi.org/10.1111/ppl.12144

Dietary micronutrient deficiencies (MNDs) are widespread, yet their prevalence can be difficult to assess. Here, we estimate MND risks due to inadequate intakes for seven minerals in Africa using food supply and composition data, and consider the pot... Read More about Dietary mineral supplies in Africa.

A scanner system for high-resolution quantification of variation in root growth dynamics of Brassica rapa genotypes (2014)
Journal Article
variation in root growth dynamics of Brassica rapa genotypes. Journal of Experimental Botany, 65(8), 2039-2048. https://doi.org/10.1093/jxb/eru048

The potential exists to breed for root system architectures that optimize resource acquisition. However, this requires the ability to screen root system development quantitatively, with high resolution, in as natural an environment as possible, with...

Soil-type influences human selenium status and underlies widespread selenium deficiency risks in Malawi (2013)
Journal Article
Hurst, R., Siyame, E. W., Young, S. D., Chilimba, A. D., Joy, E. J., Black, C. R., …Broadley, M. R. (2013). Soil-type influences human selenium status and underlies widespread selenium deficiency risks in Malawi. Scientific Reports, 3(1425), https://doi.org/10.1038/srep01425

Selenium (Se) is an essential human micronutrient with critical roles in immune functioning and antioxidant defence. Estimates of dietary Se intakes and status are scarce for Africa although crop surveys indicate deficiency is probably widespread in...

Uptake competition between selenium and sulphur fertilizers in sequential harvests of ryegrass: A stable isotope study
Presentation / Conference Contribution
Jiang, L., Young, S. D., Bailey, E. H., Broadley, M. R., Graham, N. S., & McGrath, S. P. (2019, October). Uptake competition between selenium and sulphur fertilizers in sequential harvests of ryegrass: A stable isotope study. Presented at 6th International Conference on Selenium in the Environment and Human Health (ICSEHH 2019), Yangling, Xi'an, China

The demand for sulphur (S) fertilizers has increased due to declining S emissions from coal burning and subsequent deposition on agricultural land. Slow-release S may only be beneficial for grass Selenium (Se) status initially and less beneficial for...
