Zinc (Zn) is an essential nutrient for plants, with a crucial role as a cofactor for many enzymes. Approximately one-third of the global arable land area is Zn deficient, leading to reduced crop yield and quality. To improve crop tolerance to Zn defi...

Journal Article
Norton, G. J., Travis, A. J., Danku, J., Salt, D. E., Hossain, M., Islam, M. R., & Price, A. H. (2017). Biomass and elemental concentrations of 22 rice cultivars grown under alternate wetting and drying conditions at three field sites in Bangladesh. Food and Energy Security, 6(3), https://doi.org/10.1002/fes3.110

As the global population grows, demand on food production will also rise. For rice, one limiting factor effecting production could be availability of fresh water, hence adoption of techniques that decrease water usage while maintaining or increasing...

Role of LOTR1 in nutrient transport through organization of spatial distribution of root endodermal barriers (2017)
Journal Article
Li, B., Kamiya, T., Kalmbach, L., Yamagami, M., Yamaguchi, K., Shigenobu, S., …Fujiwara, T. (2017). Role of LOTR1 in nutrient transport through organization of spatial distribution of root endodermal barriers. Current Biology, 27(5), https://doi.org/10.1016/j.cub.2017.01.030

The formation of Casparian strips and suberin lamellae at the endodermis limits the free diffusion of nutrients and harmful substances via the apoplastic space between the soil solution and the stele in roots [1–3]. Casparian strips are ring-like lig... Read More about Role of LOTR1 in nutrient transport through organization of spatial distribution of root endodermal barriers.

Nuclear localised more sulphur accumulation1 epigenetically regulates sulphur homeostasis in Arabidopsis thaliana (2016)
Journal Article
Huang, X., Chao, D., Koprivova, A., Danku, J., Wirtz, M., Müller, S., …Salt, D. E. (2016). Nuclear localised more sulphur accumulation1 epigenetically regulates sulphur homeostasis in Arabidopsis thaliana. PLoS Genetics, 12(9), 1-29. https://doi.org/10.1371/journal.pgen.1006298

Sulphur (S) is an essential element for all living organisms. The uptake, assimilation and metabolism of S in plants are well studied. However, the regulation of S homeostasis remains largely unknown. Here, we report on the identification and charact...

A heavy metal P-type ATPase OsHMA4 prevents copper accumulation in rice grain (2016)
Journal Article
Huang, X., Deng, F., Yamaji, N., Pinson, S. R., Fujii-Kashino, M., Danku, J., …Ma, J. F. (2016). A heavy metal P-type ATPase OsHMA4 prevents copper accumulation in rice grain. Nature Communications, 7(12138), https://doi.org/10.1038/ncomms12138

Rice is a major source of calories and mineral nutrients for over half the world’s human population. However, little is known in rice about the genetic basis of variation in accumulation of copper (Cu), an essential but potentially toxic nutrient. He...

The MYB36 transcription factor orchestrates Casparian strip formation (2015)
Journal Article
Kamiya, T., Borghi, M., Wang, P., Danku, J., Kalmbach, L., Hosmani, P. S., …Salt, D. E. (2015). The MYB36 transcription factor orchestrates Casparian strip formation. Proceedings of the National Academy of Sciences, 112(33), https://doi.org/10.1073/pnas.1507691112

The endodermis in roots acts as a selectivity filter for nutrient and water transport essential for growth and development. This selectivity is enabled by the formation of lignin-based Casparian strips. Casparian strip formation is initiated by the l...
