Scientists analyze the molecular mechanism of crop grain filling and phosphorus utilization

On April 29, "Nature-Genetics" published online a research paper completed by the He Zuhua research group of the Center for Excellence in Molecular Plant Science of the Chinese Academy of Sciences, the School of Life Sciences, Shanghai University of Science and Technology, and the University of California, Berkeley.

In recent years, yield and fertilizer utilization have been the main improvement targets for agricultural production and breeding.

Studies have shown that OsPHO1;2 can mediate phosphorus transport between root-stem tissues at the seedling stage, but there is no direct evidence that PHO1 type protein is a phosphorus transporter.

The stable state of Pi during the grain filling process is very important.

At the same time, the researchers also found that the corn homologous gene ZmPHO1;2 can also regulate the process of corn grain filling and phosphorus redistribution, indicating that the process of grain filling regulation mediated by PHO1 family proteins is highly conserved in cereal crops.

The research work was first completed with Shanghai University of Science and Technology, and was funded by the National Key Research and Development Program, the pilot project of the Chinese Academy of Sciences , and the State Key Laboratory of Plant Molecular Genetics.
