Summary
Lindsay and Maathuis review emerging molecular mechanisms underlying arsenic uptake and accumulation in crops, as understood through plant physiology and genetics research circa 2017. The paper contextualises these mechanisms within the food safety problem posed by arsenic contamination of staple crops, particularly rice, and considers how such knowledge might inform breeding strategies or agronomic practices to mitigate human dietary exposure. The review does not present original experimental data but synthesises the state of knowledge on arsenic transport pathways in plant tissues.
UK applicability
Whilst arsenic contamination is less acute in UK-grown cereals than in South Asian rice production, understanding arsenic uptake mechanisms has relevance to UK food security and imports. Knowledge of genetic variation in arsenic accumulation could inform crop improvement programmes relevant to UK agriculture and food standards.
Key measures
Molecular pathways of arsenic uptake and accumulation; genetic and physiological mechanisms in crop plants
Outcomes reported
The review synthesises current understanding of molecular and genetic mechanisms by which plants take up, transport and accumulate arsenic, with implications for crop breeding and agronomic intervention.
