Cytomixis doesn’t induce obvious changes in chromatin modifications and programmed cell death in tobacco male meiocytes [PDF]

open access: yesFrontiers in Plant Science, 2015
Cytomixis is a poorly studied process of nuclear migration between plant cells. It is so far unknown what drives cytomixis and what is the functional state of the chromatin migrating between cells.

Serial Block-Face Scanning Electron Microscopy Reveals That Intercellular Nuclear Migration Occurs in Most Normal Tobacco Male Meiocytes [PDF]

open access: yesFrontiers in Plant Science, 2021
Serial block-face scanning electron microscopy (SBF-SEM) was used here to study tobacco male meiosis. Three-dimensional ultrastructural analyses revealed that intercellular nuclear migration (INM) occurs in 90–100% of tobacco meiocytes.
