Whole-genome duplication (WGD) occurs in all kingdoms and impacts speciation, domestication, and cancer outcome. However, doubled DNA management can be challenging for nascent polyploids. The study of within-species polyploidy (autopolyploidy) permit...

Hyperaccumulators are a group of plant species that accumulate high concentrations of one or more metal(loid)s in their above-ground tissues without showing any signs of toxicity. Several hyperaccumulating species belong to the Brassicaceae family, a... Read More about De novo transcriptome assembly of hyperaccumulating Noccaea praecox for gene discovery.

Plants adapted to challenging environments offer fascinating models of evolutionary change. Importantly, they also give information to meet our pressing need to develop resilient, low-input crops. With mounting environmental fluctuation—including tem... Read More about Chasing the mechanisms of ecologically adaptive salinity tolerance.

The influences of stomatal size and density on rice abiotic stress resilience (2023)
Journal Article
Caine, R. S., Harrison, E. L., Sloan, J., Flis, P. M., Fischer, S., Khan, M. S., Nguyen, P. T., Nguyen, L. T., Gray, J. E., & Croft, H. (2023). The influences of stomatal size and density on rice abiotic stress resilience. New Phytologist, 237(6), 2180-2195. https://doi.org/10.1111/nph.18704

A warming climate coupled with reductions in water availability and rising salinity are increasingly affecting rice (Oryza sativa) yields. Elevated temperatures combined with vapour pressure deficit (VPD) rises are causing stomatal closure, further r...

Transcriptional networks underpinning ploidy related increased leaf potassium in neo-tetraploids (2022)
Journal Article
Fischer, S., Flis, P., Zhao, F.-J., & Salt, D. E. (in press). Transcriptional networks underpinning ploidy related increased leaf potassium in neo-tetraploids. Plant Physiology, 190(3), 1715-1730. https://doi.org/10.1093/plphys/kiac360

Whole-genome duplication generates a tetraploid from a diploid. Newly created tetraploids (neo-tetraploids) of Arabidopsis (Arabidopsis thaliana) have elevated leaf potassium (K), compared to their diploid progenitor. Micro-grafting has previously es...

Targeted expression of the arsenate reductase HAC1 identifies cell type specificity of arsenic metabolism and transport in plant roots (2020)
Journal Article
Fischer, S., Sánchez-Bermejo, E., Xu, X., Flis, P., Ramakrishna, P., Guerinot, M. L., Zhao, F. J., & Salt, D. E. (2021). Targeted expression of the arsenate reductase HAC1 identifies cell type specificity of arsenic metabolism and transport in plant roots. Journal of Experimental Botany, 72(2), 415-425. https://doi.org/10.1093/jxb/eraa465

High Arsenic Concentration 1 (HAC1), an Arabidopsis thaliana arsenate reductase, plays a key role in arsenate [As(V)] tolerance. Through conversion of As(V) to arsenite [As(III)], HAC1 enables As(III) export from roots, and restricts translocation of...
