2003 journal article

Analysis of trans-silencing interactions using transcriptional silencers of varying strength and targets with and without flanking nuclear matrix attachment regions

TRANSGENIC RESEARCH, 12(3), 305–318.

By: R. Ascenzi n, B. Ulker, J. Todd, D. Sowinski, C. Schimeneck, G. Allen, A. Weissinger, W. Thompson 

author keywords: matrix attachment region; tobacco; transcriptional gene silencing; transgene expression; trans-silencing
MeSH headings : Gene Silencing; Inheritance Patterns; Matrix Attachment Regions / genetics; Seedlings / genetics; Sequence Homology; Silencer Elements, Transcriptional; Tobacco / genetics; Transcription, Genetic
TL;DR: The results are consistent with a model in which transcriptional silencing is triggered by transcription of sequences during the early stages of embryo or seedling development. (via Semantic Scholar)

2001 journal article

The role of cell differentiation state and HMG-I/Y in the expression of transgenes flanked by matrix attachment regions

TRANSGENIC RESEARCH, 10(5), 465–470.

By: R. Ascenzi n, J. Ingram  n, M. Massel n, W. Thompson n , S. Spiker n & A. Weissinger n

author keywords: cell differentiation and proliferation; chromatin; matrix; scaffold attachment region (MAR/SAR); plant high mobility group-I/Y protein (HMG-I/Y); transgene expression; tobacco
MeSH headings : Cell Differentiation; Cells, Cultured; Gene Expression; HMGA1a Protein / genetics; HMGA1a Protein / metabolism; Plants, Genetically Modified; Tobacco / cytology; Tobacco / genetics
TL;DR: It appears that tobacco nuclear matrix attachment region function is not enhanced simply because cells in culture divide rapidly and are not differentiated. (via Semantic Scholar)

1999 journal article

Subnuclear distribution of the entire complement of linker histone variants in Arabidopsis thaliana

CHROMOSOMA, 108(6), 345–355.

By: R. Ascenzi* & J. Gantt*

MeSH headings : Antibody Specificity; Arabidopsis / genetics; Arabidopsis Proteins; Cell Nucleus / genetics; Cell Nucleus / metabolism; Chromatin / chemistry; Chromatin / metabolism; Cross-Linking Reagents / chemistry; DNA, Plant / immunology; DNA, Plant / isolation & purification; DNA, Ribosomal / metabolism; Fluorescent Antibody Technique, Indirect; Formaldehyde / chemistry; Gene Dosage; Histones / genetics; Histones / immunology; Histones / metabolism; In Situ Hybridization; Interphase; Plant Proteins / genetics; Plant Proteins / metabolism; Precipitin Tests; Repetitive Sequences, Nucleic Acid; Telomere / metabolism; rab GTP-Binding Proteins
TL;DR: The results suggest that plants, as has been shown for animals, possess a variant linker histone that is differentially localized and is bound to the compacted nucleosomal arrays at the telomere but with reduced stoichiometry. (via Semantic Scholar)
