A small RNA-based gene silencing process in which small interfering RNAs (siRNAs) guide DNA methylation to the siRNA-generating genomic loci and other loci that are homologous to the siRNAs for de novo DNA methylation. This results in a heterochromatin assembly, a chromatin conformation that is refractory to transcription. In general this process consists of three phases: biogenesis of siRNAs, scaffold RNA production, and the formation of the guiding complex that recruits de novo DNA methyltransferases to the target loci. Transposable elements are silenced by this mechanism.

A heterochromatin formation-based gene silencing process mediated by a small RNA molecule that occur before the beginnning of trancription.

Growth of a plant structure from the time of its initiation by an apical meristem until its expansion is completed.

The last stage of flower development during which programmed degradation of macromolecules and nutrient recycling take place.

The process that results in the fluctuations in intracellular calcium that are responsible for the initiation of movement as a component of the process of cerebral cortex glial-mediated radial migration.

Signaling between members of the neurotrophin family and their receptors that result in the start of cell motility as a component of the process of cerebral cortex glial-mediated radial migration.

The interaction of soluble factors and receptors that result in the movement of cells in the primitive cerebral cortex.

The initial stages of cell motility involved in the glial-mediated movement of cells in the developing cerebral cortex.

The migration of cells in the cerebral cortex in which cells move orthogonally to the direction of radial migration and do not use radial glial cell processes as substrates for migration.

The orderly movement of cells from one site to another in the cerebral cortex.

The migration of cells in the developing cerebral cortex in which cells move from the ventricular and/or subventricular zone toward the surface of the brain.

The orderly movement of glial cells through the telencephalon.

The process that results in the loss of attachments of a cell in the ventricular zone.

The movement of a cell body from the ventricular zone to the pial surface with a concomitant shortening of the process that extends to the pial surface.

The radial migration of cells from the ventricular zone that is independent of radial glial cells. Cells extend processes that terminate at the pial surface and follow the processes as they migrate.

The extension of a long process to the pial surface as a cell leaves the ventricular zone.

The detachment of cells from radial glial fibers at the appropriate time when they cease to migrate and form distinct layer in the cerebral cortex.

The microtubule-mediated movement of the nucleus that is required for the movement of cells along radial glial fibers as a component of the process of cerebral cortex glial-mediated radial cell migration.

The changes in the actin cytoskeleton that are necessary for the movement of cells along radial glial cells as a component of the process of cerebral cortex glial-mediated radial cell migration.

Signaling between growth factors and their receptors that results in the start of cell movement, where this process is involved in glial-mediated radial migration in the cerebral cortex.
