The pectin is protectin': Study uncovers a plant barrier against toxic aluminum
Aluminum toxicity has long been known to damage plant cells and inhibit the growth of plants. Aluminum is widely found in soils that are too acidic, and as human activities have increased soil acidity across the globe, aluminum toxicity has become a leading cause of low crop yield worldwide. While the effect of aluminum on plants is widely known, precisely how aluminum enters plant cells and causes harm is not well understood. In a new study published in Frontiers in Plant Science, researchers at the University of Tsukuba have found that an integral part of a plant's cell wall may play a role in protecting rice plants from soil aluminum.
