Vitamin E, Glucosinolate Contents in Rapeseed

 

Chinese researchers identify mechanism regulating vitamin E, glucosinolate contents in rapeseed

WUHAN -- A Chinese research team has uncovered the molecular mechanism behind the regulation of vitamin E and glucosinolate contents in rapeseed.

Vitamin E is a crucial nutrient for the growth and development of humans and animals. It plays a vital role in boosting the immune system, delaying the aging process and preventing cancer, among other significant functions.

A research team at the Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences employed genome-wide association analysis to detect a major effect, coded QTL-qVE.C02, which is associated with vitamin E content in a Brassica napus population.

Through genetic complementation and site-directed mutagenesis processes, researchers successfully cloned the target gene of the QTL-qVE.C02 effect, coded BnaC02.VTE4, and identified a point mutation that is the direct cause of the differences in vitamin E and glucosinolate contents in rapeseed.

The team also combined analysis types to elucidate the competitive relationship between the biosynthetic pathways of vitamin E and glucosinolate, and revealed the molecular mechanism behind the BnaC02.VTE4 gene's positive regulation of vitamin E and negative regulation of glucosinolate in rapeseed.

The researchers say that their study can contribute to the breeding of rapeseed with high vitamin E and low glucosinolate contents.

The study was published in the Plant Biotechnology Journal.

New Frost-Resistant Sand-Control Agent

  Across China: Chinese researchers develop new frost-resistant sand-control agent LANZHOU -- A Chinese research team has developed a chemical sand-fixation material suitable for use in cold desert regions, which is expected to serve as a new tool for sand control and desertification prevention in such areas. The application of chemical materials to stabilize shifting sands is one of the primary methods of desertification control. This approach involves the use of adhesive chemical substances to bind loose sand particles together, thereby mitigating encroachment by wind-blown sand. However, conventional chemical sand-fixation materials have been mainly designed for hot and arid regions. In colder, high-altitude or high-latitude desert regions, such as the Qinghai-Xizang Plateau and the Mongolian Plateau, which are located in Northwest, Southwest and North China, cooler temperatures often render traditional methods of sand control ineffective. Researchers from the Northwest Institut...

Bamboo In The World’s Longest Sea Bridge

  How Chinese engineers used bamboo in the world’s longest sea bridge, and more Chinese scientists have been working on new technologies to make stronger and more durable bamboo-based materials for large-scale infrastructure, reinforcing the country’s position as a leader in the emerging eco-friendly industry. Bamboo, which is known for its rapid growth and high strength, was engineered into composite panels used on the scenic platforms that stretch for kilometres along the  Hong Kong-Zhuhai-Macau Bridge , the official Science and Technology Daily reported on Wednesday. Six years after they were installed on the bridge – the world’s largest sea crossing – the bamboo-based panels have withstood sunlight, typhoons and seawater corrosion, remaining “as solid as ever”, according to the report. Lou Zhichao, from Nanjing Forestry University’s Bamboo Research Institute, said most of the world’s bamboo was grown in developing countries. “China is not only the world’s largest bamboo pr...

Blueprint Of Human Brain Cortex

  Chinese scientists uncover complex blueprint of human brain cortex BEIJING -- Researchers from the Institute of Automation at the Chinese Academy of Sciences have revealed the intrinsic relationship between the topological structure of human brain cortex connections and genetic characteristics, according to a study published in the Journal of Neuroscience. Fan Lingzhong, a researcher at the institute, explained that neural networks operate as human think, learn, or perceive the world, with trillions of connections enabling rapid information transfer. The study addresses a fundamental question: How do these intricate connections form, and why do distinct brain regions exhibit such orderly distribution across the cortex? "The brain begins following a genetic 'blueprint' during embryonic development," Fan noted. Researchers proposed a hypothesis: genetic encoding and cortical connectivity are not directly correlated due to the vast numerical disparity between genes and...
