Nuclear Cytometry: Analysis of the Patterns of DNA Synthesis and Transcription Using Flow Cytometry, Confocal Microscopy, and RNA Sequencing.
This chapter illustrates the application of flow cytometry combined with confocal microscopy to analyze complex organs, focusing on properties of the plant nucleus, and goes on to describe how suspensions of nuclei can be prepared from tissues and organs, and used for flow cytometric analysis of cellular and transcriptional states.

Increases in nuclear volume and cell size in meristematic cells arrested by 5-aminouracil
It appears that in cells blocked by 5-AU growth continues for about 12 hours, suggesting that synthesis of nuclear components is favoured at the expense of cytoplasmic constituents, at least during the first 6 hours of treatment; there is an internal imbalance between nuclear and cell growth and a temporary change in the nuclear cytopLasmic ratio.

Presence of small-nuclear-ribonucleoprotein-containing nuclear bodies in quiescent and early germinatingZea mays embryos
It is concluded that the NABs present in such tissues already contain components characterizing snRNPs (small nuclear ribonucleoproteins) in mature tissues. Expand
Cellular responses of leaf explants of Cocos nucifera L. in vitro
It is suggested that this uncoupling of cell and nuclear size disrupts cell co-ordination and is a key contributor to recalcitrant cellular behaviour of this species in vitro. Expand
Changes in Nuclear DNA Content, Cell and Nuclear Size, and Frequency of Cell Division in the Cotyledons of Brassica napus L. during Embryogenesis
Cellular behaviour was examined during embryogenesis in Brassica napus to test whether or not polyploidy occurs in the cotyledons during the phase of oil deposition, which differs from what is known about cellular development in legume cotYledons. Expand
Methylxanthines inhibit nucleologenesis in binucleate cells
It is suggested that methylxanthines inhibit nucleologenesis: this parallels the inhibition of both cell and nuclear growth by these drugs. Expand
Inhibition of cell growth in roots of Allium cepa by caffeine and isobutylmethylxanthine
It appears that profound disturbances of cell and nuclear growth are induced in A. cepa by even a 1 hr treatment with caffeine or IBMX. Expand
Response of Zea mays Roots to 5-Aminouracil: Size Parameters of Enlarged Cells Return to Normal Values as Cells Proliferate
The response to 5-AU appeared to be determined by the inherent growth characteristics of the particular subpopulation of cells under study, with the greatest overall increase in size occurred in cells of row I, but the relative increase in cell area and nuclear volume was greatest in row II cells.
