Thallium has been used geochemical exploration of gold deposits. However, as an indicator element in searching for hydrothermal the T1 minerals and mineralization are rare in nature. Lorandite T1AsS2, a relatively uncommon mineral, has been dominantly discovered in some Carlin gold deposits, and minor Sb- Hg, U and Pb-Zn-Ag deposits.

Base editing using CRISPR technologies is an invaluable tool for crop breeding. One of the major base editors, the adenine base editor(ABE), has been successfully used in both model plants and many ***, owing to limited editing efficiency, the ABE has been difficult to apply in polyploid crops such as allohexaploid bread wheat that often require simultaneous mutation of multiple alleles for fast breeding. We have designed a wheat high-efficiency ABE(Whie ABE), using the newly developed high-activity adenosine deaminase Tad A8 e. In vivo and in vitro analysis demonstrated the improved applicability of Tad A8 e over the commonly used Tad A7.10. Dinitroaniline is a widely used herbicide with high effectiveness and low toxicity to animals. However, wheat cultivars with tolerance to dinitroaniline are rare, limiting the application of dinitroaniline in wheat planting. Using A-to-G editing with Whie ABE, we found that a Met-to-Thr mutation in wheat tubulin alleles located on chromosomes 1 A, 1 B, 1 D, 4 A, and 4 D increased the resistance of wheat to dinitroaniline, revealing a dosage effect of edited tubulins in resistance. The Whie ABE promises to be a valuable editing tool for accelerating crop improvement and developing herbicide-resistant wheat germplasm.
