China's gene technology to fight rice "cancer" has made a major breakthrough.

Biotechnology Channel News: Rice plague is called rice "cancer" and is the main disease affecting the reduction of rice production in China.
he Zuhua team of Shanghai Institute of Plant Physiology and Ecology of the Chinese Academy of Sciences effectively selected and bred new varieties of broad-spectrum disease resistance by excavating new gene site and analyzing its functional mechanism, which provided a cost-effective method for controlling rice plague.
results were recently published online in science, an internationally renowned journal.
rice is one of the most important food crops, and scientists have been trying to solve the problem of high yield and disease resistance of rice for many years.
the use of pesticides, the proven effective way to combat rice pestilence is to grow disease-resistant varieties.
However, the current identification of anti-rice pestilence genes, the vast majority of antispectral narrow, single application value is not great, but if these disease-resistant genes into one variety to improve disease resistance, but also tend to reduce the yield and quality of rice.
bottleneck break through? He Zuhua team with breeders, extensive screening of anti-plague species, after large-scale genetic analysis, cloning the broad-spectrum anti-rice plague gene Pigm, and systematically analyzed its functional mechanism.
He Zuhua, Pigm has long-lasting resistance to disease, and there are two genes at its point: one that is resistant to disease but reduces yield, and one that is not disease-resistant but increases production.
these two genes together can achieve a broad-spectrum disease resistance and yield balance, but also make pathogens can not evolve and destroy rice disease resistance.
this study not only theoretically expands the understanding of plant immunity and disease resistance mechanisms, but also provides effective new tools for crop disease-resistant breeding.
since the excavation, Pigm has been widely used in rice disease-resistant breeding in China, and new varieties have been tested and tested.
