Scientists from China and the United States cooperated and discovered a gene related to the salt tolerance of rice. This research, jointly completed by Lin Hongxuan, a researcher at the Shanghai Institute of Plant Physiology and the Chinese Academy of Sciences’ Berkeley Department of Plant and Microbiology, will be published in the October issue of Nature Genetics.
Salt content in soil is a key factor in limiting crop yields. A better understanding of the genetic basis of salt tolerance in natural crops may help to find ways to better improve the salt tolerance of crops.
In a telephone interview with reporters, Prof. Lu Sheng said: “The Lin Hongkai and others of the Shanghai Institute of Plant Physiology started this study and later we conducted a more in-depth study. The sodium salt is a salt in the soil, and sodium ions. Harmful to plant growth, we discovered a variant of the SKC1 gene in a Japanese glutinous rice called NonaBokra, which allows the sodium ions to circulate in the plants and let them enter less important parts of the plant, such as the roots, rather than Enter important parts such as leaves and stems, thus ensuring the growth of important parts. SKC1 gene is encoded as a sodium ion carrier protein, and this carrier protein plays an important role in the sodium ion cycle."
He graduated from the Shanghai Institute of Plant Physiology to graduate student from 1982 to 1985 and went to the United States in 1986. He believes that the SKC1 gene in Japan's NonaBokra glutinous rice is more active than the salt-sensitive Japanese rice Koshihikari's SKC1 gene, which is more efficient in transporting sodium ions from the aerial parts of plants (leaves and stems) to the roots, which in turn releases sodium ions. Into the soil. Therefore, this Japanese japonica rice has stronger salt tolerance.
