Chinese scientists discovered a possible "death switch" mechanism in plant's immune system. It triggers infected cells to self-destruct, thus limits spread of disease and keeps other parts of plant healthy.
It is usually harmless to plants as it only affects diseased cells, which are a tiny portion of entire plant.
Its discovery provides clue about cell death control and immunity for plants.
More research on it can help to produce new generation of more environmentally friendly and disease-resistant crops that would use fewer pesticides.
Scientists from Tsinghua University and Chinese Academy of Sciences' Institute of Genetics and Development Biology did the research.
