TL;DR: A SAL1-PAP retrograde pathway that can alter nuclear gene expression during HL and drought stress is proposed and it is shown that PAP is a primary in vivo substrate.

TL;DR: Data demonstrate that Cys and also sulfide must be sufficiently exchangeable between cytosol and organelles, and despite partial redundancy, the mitochondria and not the plastids play the most important role for Cys synthesis in Arabidopsis.

TL;DR: The data indicate that the APK1 and APK2 isoforms of APS kinase play a major role in the synthesis of secondary sulfated metabolites and are required for normal growth rates.

TL;DR: The results support thatSiR is the only gene with this function in the Arabidopsis genome, that optimal activity of SiR is essential for normal growth, and that its downregulation causes severe adaptive reactions of primary and secondary metabolism.

TL;DR: It is reported that SULTR3;1 is localized in the chloroplast, which was demonstrated by SUL TR 3;1-GFP localization, Western blot analysis, protein import as well as comparative analysis of sulfate uptake by chloroplasts between knockout mutants, complemented transgenic plants, and the wild type.
