Brassica crops accumulate specific sulfur (S)-containing compounds, glucosinolates (GSL), in their seeds. GSL function plant defense, but a few exert toxic effects on animals. Rapeseed (Brassica napus) cultivars accumulating low levels of have been bred to avoid the GSL. store S support early seedling growth Arabidopsis under deficiency. In this study, we tested different conditions and metabolism B. napus containing high concentrations seeds (hereafter referred as high- low-seed cultivars, respectively) determine appropriate fertilizer design for napus. Seed content was lower than that ones, indicating seed can contribute accumulation Under S-sufficient (+S) -deficient (–S) conditions, both shoots roots fresh weights were similar among leaves turned yellowish cultivars. The sulfate cysteine seedlings glutathione high-seed especially grown – conditions. protein fraction those These results indicated help deficiency lack affected shoot rather root growth. Thus, recommend applying fertilizers minimizing use This study provides novel insights designing according cultivar soil environment.

Selenate, the most common form of selenium (Se) in soil environments, is beneficial for higher plants. Selenate similar to sulfate terms structure and manner assimilation by plants, which involves reduction selenate selenide replacement an S moiety organic compounds such as amino acids. The nonspecific incorporation seleno-amino acids into proteins induce Se toxicity alters plant metabolism, particularly comparable responses deficiency (−S). However, previous analyses involved high concentrations selenate, effects lower doses have not been elucidated. In this study, we analyzed metabolic changes induced treatment through a non-targeted metabolome analysis found that 2 µM decreased assimilates acids, increased flavonoids, while glutathione levels were maintained. results suggest decrease acid levels, detected under −S, along with disruptions assimilation, biosynthesis pathways, energy present primary influences selenate. These targets metabolism first, induces oxidative stress mitigation, represented flavonoid accumulation, key adaptive response, providing novel, possible mechanism adaptation.

Gypsum (calcium sulfate) are commonly used to improve subsoil acidity. Aluminum (Al) toxicity in acid soil reduces crop yields worldwide, especially the tropical regions. In soil, sulfate decrease Al and improves plant growth yield. Here, we aimed investigate effects of CaSO4 on stress Al-tolerant accession Col-0 as well Al-sensitive accessions, Wei-0 Ts-5, Arabidopsis thaliana using hydroponics. Our research indicates that supply has a significant effect root malate release compared CaCl2 under stress, accessions. response enhanced expression transporter gene AtALMT1 SULTR3;5, which were regulated by Al-resistant transcription factor STOP1. Furthermore, knockout lines SULTR3;5 SULTR2;1, involved uptake translocation, more than wild type without CaSO4, was reduced with decreased expression. conclusion, one alleviative gypsum application rhizotoxicity is promoted through organic mechanism enhancing expression, alongside Ca2+ reduction Al3+ activity plasma membrane.
