Accurate-parametric SAR-TL dating protocols for older sediments using quartz.
Gu Y, Wang M, Zhang Q, Ge L, Xu L, Lu H. Gu Y, et al. Appl Radiat Isot. 2022 Mar;181:110072. doi: 10.1016/j.apradiso.2021.110072. Epub 2021 Dec 24. Appl Radiat Isot. 2022. PMID: 34968882 Review.
However, for changes in the characteristics of quartz, the larger deviation is still a problem in TL dating, especially with the single-aliquot regeneration-does (SAR) procedure. In the SAR-TL protocol, changes in the characteristics of quartz inevitably cause a shi …

Systemic acquired resistance.
Durrant WE, Dong X. Durrant WE, et al. Annu Rev Phytopathol. 2004;42:185-209. doi: 10.1146/annurev.phyto.42.040803.140421. Annu Rev Phytopathol. 2004. PMID: 15283665 Review.
Much progress has been made recently in elucidating the mechanism of SAR. Using the model plant Arabidopsis, it was discovered that the isochorismate pathway is the major source of SA during SAR. In response to SA, the positive regulator protein NPR1 moves to the nu …
