Open AccessSARS-COV-2 spike protein promotes RPE cell senescence via the ROS/P53/P21 pathway
SARS-Cov-2 infection, which has caused the COVID-19 global pandemic, triggers cellular senescence. In this study, we investigate the role of the SARS-COV-2 spike protein (S-protein) in regulating the senescenc...

Open AccessA central circadian oscillator confers defense heterosis in hybrids without growth vigor costs
Plant immunity frequently incurs growth penalties, which known as the trade-off between immunity and growth. Heterosis, the phenotypic superiority of a hybrid over its parents, has been demonstrated for many t...
