Glucosinolates (GSLs) are of interest for potential antimicrobial activity of their degradation products and exclusive presence in Brassicaceae. Compositional changes of aliphatic, benzenic, and indolic GSLs of , , and seeds by germination and fungal elicitation were studied. (nonpathogenic), (nonpathogenic), and (pathogenic) were employed. Thirty-one GSLs were detected by reversed-phase ultrahigh-performance liquid chromatography photodiode array with in-line electrospray ionization mass spectrometry (RP-UHPLC-PDA-ESI-MS). Aromatic-acylated derivatives of 3-butenyl GSL, -hydroxybenzyl GSL, and indol-3-ylmethyl GSL were for the first time tentatively annotated and confirmed to be not artifacts. For , germination, elicitation, and elicitation increased total GSL content, mainly consisting of -hydroxybenzyl GSL, by 2-3 fold. For and , total GSL content was unaffected by germination or elicitation. In all treatments, aliphatic GSL content was decreased (≥50%) in and remained unchanged in . Indolic GSLs were induced in all species by germination and nonpathogenic elicitation.

Glucosinolates (GSLs) are important secondary metabolites abundantly distributed in Brassicaceae plants, whose degradation products benefit plant resistance but are regarded as disadvantageous factors for human health. Thus, reducing GSL content is an important goal in the breeding program in crops, such as . In this study, 1280 genes in the GSL pathway were identified from 14 land plant genomes, which are specifically distributed in Brassicaceae and are extensively expanded in .

WHIRLY1 belongs to a family of plant-specific transcription factors capable of binding DNA or RNA in all three plant cell compartments that contain genetic materials. In Arabidopsis thaliana, WHIRLY1 has been studied at the later stages of plant development, including flowering and leaf senescence, as well as in biotic and abiotic stress responses. In this study, WHIRLY1 knockout mutants of A.

Cell surface glycosylation plays an important role in immune cells; however, the N-glycosylation and glycosphingolipid (GSL) signatures of activated microglia are poorly understood. Here, we study comprehensive combined transcriptomic and glycomic profiles using human induced pluripotent stem cells-derived microglia (hiMG).

The article presents the results of a three-year field study that was conducted in Poland to evaluate the yield and quality of seeds and oil from traditional (SAM) and canola-quality white mustard (SAC) in response to different N fertilizer rates (0, 40, 80, 120, and 160 kg ha). Seed yields were 25% higher in SAM than SAC. The seeds of SAC contained more crude fat (by 3%) and crude fiber (by 6%) than the seeds of SAM.
