Chen Yuhang and Zhou Jianmin, a cooperative team of the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, recently cloned a broad-spectrum anti clubroot gene and named it after Wei Qing, a famous general in the Western Han Dynasty. Relevant research results were published in the international academic journal Cell on June 8, Beijing time.

Root swelling disease is the largest disease in the agricultural production of cruciferous crops such as rapeseed. Root swelling bacteria can survive in soil for 20 years, and once farmland is contaminated, it will no longer be suitable for planting cruciferous crops. In recent years, root rot disease has been rapidly spreading in China, accounting for approximately 30% of the planting area of cruciferous crops in the country.

The research team isolated and identified the highly resistant root nodule disease gene WTS and elucidated its mechanism of action. WTS encodes a protein that has never been reported before, and after being introduced into rapeseed, it not only exhibits good resistance but also completely normal growth and development; Rapeseed carrying WTS exhibits high resistance to multiple root nodules, indicating that WTS is a broad-spectrum resistance gene. Further research has found that when root swelling bacteria invade, WTS forms a protective barrier around the cell periphery, thereby protecting the roots from bacterial invasion. This is similar to the establishment of defense lines and resistance against the Xiongnu in the northern mountainous areas during the Qin and Han dynasties, so the gene was named after the Western Han general Wei Qing.

The team from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences has been studying plant immune mechanisms for a long time. In the early stage, they collaborated with teams such as Chai Jijie from Tsinghua University to discover plant disease resistant bodies for the first time internationally in 2019. In 2021, they discovered the calcium ion channel function of disease resistant bodies, solving the problem that has plagued the field of plant immunity for more than 20 years. Some of their achievements have been selected as one of the top ten advances in Chinese life science in 2019 and the top ten advances in Chinese agricultural science in 2021.

This study not only has good application prospects in the breeding of cruciferous crops for resistance to root knot disease, but more importantly, it is the first discovery of calcium ion release channels and their mediated immune mechanisms in plants, which is another innovative achievement.

Recently, with the approval of the National Medical Products Administration, the Class 1 innovative drug CC312 developed by Huihe Biotechnology has initiated phase I clinical trials for the treatment of recurrent/refractory CD19 positive B-cell malignant hematological tumors. This is the first domestically and the third globally approved triple specific antibody drug based on CD28 co stimulatory signals to enter clinical practice. When it comes to the development history of this new triple antibody drug, Dr. Zhu Huaxing, the founder of Huihe Biotechnology, still remembers vividly: "Before 2019, there was no triple antibody drug approved for clinical use globally, and some investors couldn't understand CC312. During a critical period of company development, Nokai Xinkang Fund invested 30 million yuan to help us complete Series A financing." Nokai Xinkang is a venture capital fund initiated by Xinze Entrepreneurship Incubator. This incubation company, which has been deeply cultivated in Zhangjiang Science City for many years

Not only can you hear Beethoven talk freely in "Moonlight", but you can also achieve precise positioning in three-dimensional scenes, and complete scene analysis through the combination of images and sound. On June 16, at the AI Framework Ecological Summit, the Institute of Automation of the Chinese Academy of Sciences officially released the full mode large model of "Zidong Taichu". This model is the 2.0 version upgraded from the 1.0 version of the 100 billion parameter multimodal model "Zidong Taichu". On the basis of voice, image and text three modes, it adds video, sensor signal, 3D point cloud and other modal data, breaks through the key technologies such as multimodal correlation for cognitive enhancement, and has full modal understanding, generation and correlation capabilities. At the meeting, Xu Bo, the director of the Institute of Automation, presented for the first time in real time the "Zidong Taichu" full modal cognitive model in music understanding

"The college entrance examination is an experience in our lives. Looking back on the preparation for the entire senior year of high school, we cannot help but marvel at the preciousness of time. No matter what difficulties we have gone through, I believe that as long as we persist, it will become my lifelong wealth. Today, after completing the morning foreign language listening and speaking test of the college entrance examination, Xiao Song, a senior student of Lingling High School, came out of the examination center of East China University of Science and Technology Affiliated Middle School. The senior year graduate sitting in a wheelchair said," Although academic and life are not small tests for me, I have faced many difficulties in adversity and have never given up on my dream of taking the college entrance examination. "Xiao Song suffered from congenital muscular dystrophy since childhood and entered Lingling High School in high school." Later, the school provided him with classrooms on low floors and close to the toilet, making it easier for him to enter and exit, allowing him to face his academic life with more confidence. At school, I met many kind and enthusiastic people
