- Title
Plant sciences: Poisonous grains.
- Abstract
The article highlights a research that addressed the way rice assimilated arsenic from the soils of paddy fields. The research found out that arsenic is taken into the plant as though it were a silicon. It noted that the mechanism involves two transporter proteins that belong to the family of aquaporins and whose mutation reduces arsenite uptake by the roots and the amount of arsenic that accumulated in shoots and grains. The article further states the importance of the study in preventing arsenic poisoning in some Asian countries.
