Chromatin regulation is a fundamental mechanism underlying stem cell pluripotency, differentiation, and the establishment of cell type-specific gene expression profiles. To examine the role of chromatin regulation in stem cells in vivo, we study regeneration in the freshwater planarian Schmidtea mediterranea. These animals possess a high concentration of pluripotent stem cells, which are capabl...

The ~1-millimeter-long animal is visualized with differential interference contrast microscopy and nuclear staining (blue). T...

Abstract The Esca disease complex includes some of the most important trunk diseases grapevines ( Vitis spp.) and causes serious yield losses in grape production worldwide. However, there has been no detailed study on its presence associated pathogens China. During 2017–2019, a preliminary field survey was conducted eight vineyards Hebei Ningxia provinces, China when unusual foliar symptoms wer...
