The scientific research results of the Sino-US scientists' cooperation will help the corn yield increase

WASHINGTON, Dec. 23 (Xinhua) -- A team of U.S. and Chinese researchers recently reported in the National
Journal that they have successfully analyzed the dual regulatory mechanism of the G protein, an important signal switch molecule in corn cells, for corn development and immune signaling, to guide the increase of corn production.
G protein is a switching molecule that plays an important role in cell signaling, consisting of α, β, γ and three sub-base. Previous studies have shown that G protein molecules play an important role in the development of plant-based tissues, and for crops such as corn, the development of sub-living tissues determines the shape of fruit spikes that affect yield, so it is important to study the molecular regulation mechanism of G-protein in corn.
there are many bottlenecks in this field, especially in the study of G-beta sub-base. Because single-leaf plants such as corn kill the genes associated with G-beta sub-base, it is impossible to analyze its function in depth.
in the latest study, researchers from China Agriculture
, Shandong University and cold spring port laboratory in the United States first confirmed that the death of corn G-beta sub-base gene mutation is caused by autoimmune, and then through genetic screening, the G-beta sub-base gene mutation occurred in the specific conditions of corn "regeneration", and for the first time show its developmental esoteric. Through association analysis, the team found a significant correlation between the G-beta sub-base gene and the number of lines in the corn spike.
researchers say the study will not only help understand the signaling capabilities of plant G protein molecules, but also provide an important basis for optimizing development and immune balance and improving the combined yield of maize and other crops.
