The epigenetic state of chromatin, gene activity and chromosomal positions are interrelated in plants. In Arabidopsis thaliana, chromosome arms are DNA-hypomethylated and enriched with the euchromatin-specific histone mark H3K4me3, while pericentromeric regions are DNA-hypermethylated and enriched with the heterochromatin-specific mark H3K9me2. We aimed to investigate how the chromosomal location affects epigenetic stability and gene expression by chromosome engineering.

Tuberous Sclerosis Complex (TSC) is a debilitating developmental disorder characterized by a variety of clinical manifestations. While benign tumors in the heart, lungs, kidney, and brain are all hallmarks of the disease, the most severe symptoms of TSC are often neurological, including seizures, autism, psychiatric disorders, and intellectual disabilities. TSC is caused by loss of function mutations in the TSC1 or TSC2 genes and consequent dysregulation of signaling via mechanistic Target of Rapamycin Complex 1 (mTORC1).

Drought stress inhibits Bunge () seedling growth and yield. Here, we studied the effects of drought stress on the different parts of seedlings through physiological, transcriptomic, and metabolomics analyses, and identified key genes and metabolites related to drought tolerance. Physiological analysis showed that drought stress increased the accumulation of hydrogen peroxide (HO), enhanced the activity of peroxidase (POD), decreased the activity of catalase (CAT) and the contents of chlorophyll b and total chlorophyll, reduced the degree of photosynthesis, enhanced oxidative damage in seedlings, and inhibited the growth of plants.

Background: Programmed cell death plays an important role in neuronal injury and death after ischemic stroke (IS), leading to cellular glucose deficiency. Glucose deficiency can cause abnormal accumulation of cytotoxic disulfides, resulting in disulfidptosis. Ferroptosis, apoptosis, necroptosis, and autophagy inhibitors cannot inhibit this novel programmed cell death mechanism.
