The response of oilseed rape to sulfur (S) restriction usually consists of increasing the components of S utilization efficiency (absorption, assimilation and remobilization) to provide S to seeds. However, source-sink relationships and S management in developing seeds under sulfate restriction are poorly understood. To address this, impacts of sulfate restrictions applied at "visible bud" or "start of pod filling" stages were studied with two genotypes (Aviso, Capitol) showing similar seed yield but higher seed weight and lower number of seeds per plant for Capitol under non-limited conditions.

synthesizes aromatic amino acids (AAAs) through the common pathway to produce the precursor, chorismate, and the three terminal pathways to convert chorismate into Phe, Tyr, and Trp. also imports exogenous AAAs through five transporters. GcvB small RNA post-transcriptionally regulates more than 50 genes involved in amino acid uptake and biosynthesis in , but the full extent of GcvB regulon is still underestimated.

Objective: Disorders of arousal (DoA) are characterized by an intermediate state between wakefulness and deep sleep, leading to incomplete awakenings from NREM sleep. Multimodal studies have shown subtle neurophysiologic alterations even during wakefulness in DoA. The aim of this study was to explore the brain functional connectivity in DoA and the metabolic profile of the anterior and posterior cingulate cortex, given its pivotal role in cognitive and emotional processing.

Aims: Alexander disease (AxD) is a leukodystrophy caused by mutations in the astrocytic filament gene GFAP. There are currently no effective treatments for AxD. Previous studies have rarely established AxD models with the patient's original GFAP mutations.

Wheat breeders are constantly looking for genes and alleles that increase grain yield. One key strategy is finding new genetic resources in the wild and domesticated gene pools of related species with genes affecting grain size. This study explored a natural population of Triticum turgidum (L.
