2024年4月12日 · The nuclear lamina links the nuclear membrane to chromosomes and plays a crucial role in regulating chromatin states and gene expression. However, current knowledge of nuclear lamina in plants is limited compared to animals and humans.
The plant nuclear lamina disassembles to regulate genome …
2023年7月3日 · In plants, the nuclear lamina is composed of a group of plant-specific, coiled-coil domain-containing proteins and lamin-binding membrane proteins, among which those belonging to the nuclear matrix constituent proteins (NMCPs) family were discovered first and have been investigated most extensively 2,3. NMCPs are highly conserved in the plant ...

Lamina of a Plant Leaf - Different Parts, Function and FAQs
The lamina plant leaf, as clear from the above article, consists of the chloroplasts and stomata, crucial for photosynthesis and gaseous exchange respectively. The area of the leaf lamina botany controls the number of stomata and the photosynthetic reaction centres thus, controlling the nutrient production and release of water vapour and oxygen.
PNET2 is a component of the plant nuclear lamina and is required …
2022年1月10日 · Tang et al. report that a conserved inner nuclear membrane protein PNET2 is an essential component of the nuclear lamina in plants. PNET2 mediates chromatin tethering to the nuclear periphery and is required to maintain the proper chromatin architecture and transcription programming that balances plant growth and stress responses.
Functional mechanisms and abnormalities of the nuclear lamina
2021年2月8日 · Karoutas and Akhtar review the roles of the nuclear lamina in chromatin-related functions, including transcription, epigenetic regulation and chromatin architecture, and their abnormalities in ...
Lamina-Associated Domains: Links with Chromosome Architecture ...
2017年5月18日 · In metazoan cell nuclei, the inner nuclear membrane is lined by the nuclear lamina (NL), a fibrous layer consisting primarily of type V intermediate filament proteins named lamins. Early electron microscopy revealed the tight apposition of a layer of condensed chromatin adjacent to the NL (Fawcett, 1966) (Figure 1 A).
The Nuclear Envelope – Structure and Protein Interactions
2017年7月17日 · In addition, a nucleoskeletal meshwork, termed the lamina in animals, underlies the INM, thereby supporting the structure and shape of the NE and the entire nucleus. To date, only two proteins have been characterized at the plant …
