Breakthrough Technologies Color Recovery after Photoconversion of H2B::mEosFP Allows Detection of Increased Nuclear DNA Content in Developing Plant Cells
Many higher plants are polysomatic whereby different cells possess variable amounts of nuclear DNA. The conditional triggering of endocycles results in higher nuclear DNA content (C value) that in some cases has been correlated to increased cell size. While numerous multicolored fluorescent protein (FP) probes have revealed the general behavior of the nucleus and intranuclear components, direct...

متن کاملGlycoproteome of Elongating Cotton Fiber Cells*
Cotton ovule epidermal cell differentiation into long fibers primarily depends on wall-oriented processes such as loosening, elongation, remodeling, and maturation. Such processes are governed by cell wall bound structural proteins and interacting carbohydrate active enzymes. Glycosylation plays a major role in the structural, functional, and localization aspects of the cell wall and extracellu...
متن کاملSystematic Application of DNA Fiber-FISH Technique in Cotton
Fluorescence in situ hybridization on extended DNA (fiber-FISH) is a powerful tool in high-resolution physical mapping. To introduce this technique into cotton, we developed the technique and tested it by deliberately mapping of telomere and 5S rDNA. Results showed that telomere-length ranged from 0.80 kb to 37.86 kb in three species, G. hirsutum, G. herbaceum and G. arboreum. However, most of ...
متن کاملMechanism of nuclear DNA replication in radicles of germinating cotton.
The mechanism of nuclear DNA replication in radicles of germinating cotton (Gossypium barbadense) was investigated. Pulse-labeling with [(3)H]thymidine indicates that replication intermediates are of small molecular weight (4-10S) and behave as if single-stranded. Prolonged labeling indicates that intermediates are of discrete size, suggesting a mechanism of discontinuous replication. Electron ...
