Transcriptome analysis during cell division in plants

Transcriptome analysis during cell division in plants.

Using synchronized tobacco Bright Yellow-2 cells and cDNA-amplified fragment length polymorphism-based genomewide expression analysis, we built a comprehensive collection of plant cell cycle-modulated genes. Approximately 1,340 periodically expressed genes were identified, including known cell cycle control genes as well as numerous unique candidate regulatory genes. A number of plant-specific ...

Control of cell division in plants.

Introduction The plant hormones auxins and cytokinins play a major role in the regulation of development and growth, in part through affecting cell division [ 11. A well-documented model system to study cell division and the involvement of phytohormones are protoplasts. For example, tobacco-leaf-mesophyll protoplasts will not divide unless an auxin and a cytokinin are added to the culture mediu...

Quantitative Analysis of Protein Dynamics during Asymmetric Cell Division

In dividing Drosophila sensory organ precursor (SOP) cells, the fate determinant Numb and its associated adaptor protein Pon localize asymmetrically and segregate into the anterior daughter cell, where Numb influences cell fate by repressing Notch signaling. Asymmetric localization of both proteins requires the protein kinase aPKC and its substrate Lethal (2) giant larvae (Lgl). Because both Nu...
