Discover the "secret weapon" of rice contention

Recently, a team of professors from Zhejiang University's School of Agriculture, Yan Longjiang, conducted genome-wide sequencing and rice-sensing experiments on the field's number one weed, weeds, and found a "secret weapon" for weeds to compete with rice, and pointed out a new genetic resource for rice breeding. The research papers were published
online on the 20th.
plants simply release "chemical weapons". During growth, plants release specific defensive chemicals into the environment, affecting the growth of neighboring plants.
study by the Yanlongjiang team found that weeds secrete a secondary metabolite called dingbu, which can significantly inhibit rice growth. They found three clusters of genes that could be synthesized into Dingbu in genomic studies. When mixed with rice, the gene cluster quickly starts to "make" dingo.
" Dingbu is a secret weapon unique to weeds, while rice does not. In addition, rice's 'killer' rice crustacean, grass can also be synthesized. "Therefore, without relying on the power of herbicides, rice is absolutely no more than weeds. Rice
C3 plants, while crops such as corn sorghum are C4 crops. In contrast, C4 plants are much more photolyceric. Scientists have been hoping to create c4 rice varieties to increase rice yields. Yan Longjiang believes that weed genetic resources can be used to serve rice breeding. The grass is a typical C4 plant, which has the same habitat and strain type as rice, and is an ideal model plant and C4 path gene supply for C4 rice breeding.
