Nucleologenesis: U3 snRNA-containing prenucleolar bodies move to sites of active pre-rRNA transcription after mitosis.
TLDR
Results suggest that components involved in pre-rRNA processing localize to discrete PNBs at the end of mitosis, similar to those reported here for the localization of U3 snRNA.
In vivo evidence that transcription and splicing are coordinated by a recruiting mechanism
TLDR
These data suggest a recruiting mechanism that regulates the localization of transcription and splicing factors in response to the initiation of active transcription, and demonstrate a very close association between RNA transcripts and transcription and pre-mRNAsplicing factors.
High resolution detection of rRNA and rDNA in plant nucleoli with different activities by in situ hybridization
TLDR
The results support the view that the plant nucleolus has a highly dynamic morphological and functional organization composed of a bipartite domain formed by FCs surrounded by DFC.
In maize, two distinct ribulose 1,5-bisphosphate carboxylase/oxygenase activase transcripts have different day/night patterns of expression.
TLDR
The results suggest that post-transcriptional mechanisms, mediated by the DST-like element might be involved in the circadian expression of the maize rca transcripts.
Organization of the double-stranded RNA-activated protein kinase DAI and virus-associated VA RNAI in adenovirus-2-infected HeLa cells.
TLDR
The results are consistent with a role for DAI and VA RNAI in protein synthesis and suggest that DAI may play an early role in ribosome biogenesis in the nucleolus in addition to its cytoplasmic role in translation.
Nucleologenesis: use of non‐isotopic in situ hybridization and immunocytochemistry to compare the localization of rDNA and nucleolar proteins during mitosis
TLDR
Reconstruction of the nucleolus originates in telophase‐specific domains which contain both rDNA and RNA polymerase I, as well as other numerous PNBs which obviously must contain the nucleolar organizers.
Dynamics of transcription and pre-mRNA splicing within the mammalian cell nucleus.
TLDR
SnRNPs as well as several non-snRNP splicing factors have been shown by immunofluorescence microscopy to be localized in a speckled pattern that is distributed in various regions throughout the nucleoplasm.
Dissecting the TOR–S6K signal transduction pathway in maize seedlings: relevance on cell growth regulation
TLDR
It is concluded that a TOR–S6K signal transduction pathway is functional in maize germination, as that found for non-photosynthetic eukaryotes.
FLOR1, a putative interaction partner of the floral homeotic protein AGAMOUS, is a plant-specific intracellular LRR
TLDR
It is shown that FLOR1 mRNA in wild type Arabidopsis thaliana is specific to inflorescence meristem, floral meristems, stamens and carpels with a spatio-temporal mRNA expression pattern during flower development that is similar to that of AGAMOUS.
Electron microscopic localization of ribosomal DNA in rat liver nucleoli by nonisotopic in situ hybridization.
TLDR
The authors' results indicate that ribosomal DNA sequences are enriched in the dense fibrillar component of the rat liver nucleolus.
