ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Astrocytic Regulation of Aberrant Perineuronal Net Formation in Mecp2‐Null Neocortex
Early closure of the critical period of plasticity and precocious formation of perineuronal nets (PNNs) occur in Rett syndrome (RTT). PNNs are essential in the modulation of neuronal plasticity and brain maturation. We determined that PNNs structurally mature earlier in the Mecp2‐null RTT model mouse brain, and that Mecp2‐null mouse astrocytes play a ...
