Electronic address:

A 2°C climate-warming scenario is expected to further exacerbate average crop losses by 3%-13%, yet few heat-tolerant staple-crop varieties are available toward meeting future food demands. Here, we develop high-efficiency prime-editing tools to precisely knockin a 10-bp heat-shock element (HSE) into promoters of cell-wall-invertase genes (CWINs) in elite rice and tomato cultivars. HSE insertion endows CWINs with heat-responsive upregulation in both controlled and field environments to enhance carbon partitioning to grain and fruits, resulting in per-plot yield increases of 25% in rice cultivar Zhonghua11 and 33% in tomato cultivar Ailsa Craig over heat-stressed controls, without fruit quality penalties.

Knowledge mining of brain connectivity in massive literature based on transfer learning.

Bioinformatics

November 2024

Britton Chance Center for Biomedical Photonics, Wuhan National Laboratory for Optoelectronics, Huazhong University of Science and Technology, Wuhan 430074, China.

Motivation: Neuroscientists have long endeavored to map brain connectivity, yet the intricate nature of brain networks often leads them to concentrate on specific regions, hindering efforts to unveil a comprehensive connectivity map. Recent advancements in imaging and text mining techniques have enabled the accumulation of a vast body of literature containing valuable insights into brain connectivity, facilitating the extraction of whole-brain connectivity relations from this corpus. However, the diverse representations of brain region names and connectivity relations pose a challenge for conventional machine learning methods and dictionary-based approaches in identifying all instances accurately.

Isomeric Population Transfer of the ^{229}Th Nucleus via Hyperfine Electronic Bridge.

Phys Rev Lett

November 2024

Center for Theoretical Physics & School of Physics and Optoelectronic Engineering, Hainan University, Haikou 570228, China.

The electronic bridge (EB) excitation of nuclei has been found as a versatile approach to efficiently excite the ^{229}Th isomers. Previous studies on EB excitation have typically disregarded the hyperfine structure as well as the decay of the excited atoms and ions by just treating the nucleus-electron coupling perturbatively. In the present work, we apply a quantum-optical approach to nonperturbatively investigate EB excitation of ^{229}Th^{3+} ions.

Reversible electrodeposition and dissolution of manganese oxide (MnO) represent an emerging electrochromic system. However, challenges such as "dead MnO" formation, limited optical modulation across a narrow wavelength range, and difficulties in scaling up have significantly hindered the development of MnO reversible electrodeposition-based electrochromic windows. In this work, we introduced Fe/Fe mediator ions into the electrolyte to suppress the Jahn-Teller effect, thereby preventing the formation of "dead MnO" and achieving stable and reversible MnO deposition/dissolution.
