27-6 CAAS Agricultural Genomics Institute breeds diploid hybrid potatoes

The team around HUANG Sangwen in Shenzhen used genome design to develop an inbred line of diploid potatoes, propagated by seeds. This might substitute the clonal propagated tetraploid crop. The estimated tuber yield of these F1 hybrids in the first plot trial is 40 tons per ha, indicating a huge yield potential. In addition, the hybrid potatoes are rich in dry matter and nutrient value.

2021/06 Xinjiang’s first heliostat thermal power plant in test operation

14,500 heliostats were installed and tested in Naomaohuzhen, Hami, Xinjiang Autonomous Region, Xinjiang’s first solar thermal power plant. The heliostats use the most advanced tower-type molten salt power generation technology to reflect sunlight to the heat storage area, which is 181 meters high. The thermal energy is converted to steam and drives a steam turbine. The annual electricity supply of the project is 198 million kWh, which can save 61,900 tons of standard coal equivalent every year. Japan JST China news, June 25, 2021

16-6 China announces “Industrial Internet Plan 2021”

According to plan, a National Industrial Internet Big Data Center will be almost completed by the end of 2021, promoting the conversion of industrial equipment and business systems to cloud computing by more than 100,000 companies. The plan also encourages large companies to build a digitization platform that suits the characteristics of SMEs, develop digitization services, and promote digitization of SMEs.

9-6 CAS Institute of Botany elucidates ripening of strawberry fruits

The group around QIN Guozheng studying the abscisic pathway (ABA) involved in fruit ripening found shown that mRNA m6A methylation, which is considered as an mRNA “epitranscriptome”, participates in the ripening control. The researchers found that m6A methylation displays a dramatic change at ripening onset of strawberry. The m6A modification in the coding sequence regions appears to be ripening-specific and tends to stabilize the mRNAs, whereas m6A around the stop codons and within the 3′ untranslated regions is generally negatively correlated with the abundance of the mRNAs. They identified thousands of transcripts with m6A hypermethylation in the coding sequence regions, including those of NCED5, ABAR, and AREB1 in the ABA biosynthesis and signaling pathway. Further analysis demonstrated that the methyltransferases MTA and MTB are indispensable for normal ripening of strawberry fruit, and MTA-mediated m6A modification promotes mRNA stability of NCED5 and AREB1, while facilitates translation of ABAR.  CAS news release, June 9, 2021

23-6 China’s „Earthlab“ begins trials to predict Earth systems on a time scale from seconds to hundreds of years

As a cooperation among CAS Institute of Atmospheric Physics and Tsinghua University, EarthLab will use a high-performance scientific computing platform to simulate the physical climate system, environmental system, ecological system, solid earth system, and space weather system as a whole. Along with other Earth simulators around the world, EarthLab will advance the understanding of not only the Earth’s spheres and their interactions, but also the Earth’s past, present and future. The Chinese name of the EarthLab is 寰 huán for „vast“. CAS news release, June 23, 2021

23-6 Artemisinin research center now under construction in Beijing

Located in Beijing’s Daxing Biopharmaceutical Center, the center, to be opened in June, 2022, covers an area of ​​73,000 square meters, with a central 13-story main building, 7-story large space laboratories on both east and west sides, priority laboratories, and animal experiments. The center, a tribute to Nobel laureate TU Youyou, will focus on the protection and development of Chinese medicine resources, quality assurance and improvement of Chinese medicine, research and development and industrialization of new medicines of Chinese medicine and its scientific basis.

21-6 Sinopec announces discovery of 1 billion t ultra-deep oil and gas field in the Tarim basin

After six years of intensive exploration activities, the field was located in the Tarim Basin Fuman district, which covers 10,000 square kilometers in the central area of ​​the Taklimakan Desert and the southern area of ​​the Tarim River. Recently, there was another discovery in the central part of the desert at the exploration well “Manfuka 2 well” in the same area. The depth of drilling reached 8470 meters and the height of the test oil column reached 550 meters, setting the deepest record for oil mining in this desert area. Japan JST China news, June 21, 2021

9-6 CAS QIBEBT achieves single-cell Raman sorting coupled sequencing of carotenoid-containing microbial cells in soil

A joint research group composed of JING Xiaoyan, GONG Yanhai and XU Teng, have developed a RAGE-Seq technology, starting from liquid-phase Raman analysis of D2O-fed soil flora, isolating and wrapping bacterial single cells with specific Raman phenotypes into skin-up droplets, and then doing downstream genome sequencing. By this method, they could cover individual single cell genomes by over 90% and elucidate individual carotenoid synthesis pathways. CAS news release, June 9, 2021
