Pascuzzi, P. E., Flores-Vergara, M. A., Lee, T.-J., Sosinski, B., Vaughn, M. W., Hanley-Bowdoin, L., … Allen, G. C. (2014, January 1). The Plant Cell, Vol. 26, pp. 102–120.
MeSH headings : Arabidopsis / genetics; Arabidopsis Proteins / genetics; Arabidopsis Proteins / metabolism; Arabidopsis Proteins / physiology; Chromatin / metabolism; Gene Expression Regulation, Plant; Matrix Attachment Regions; Nucleosomes / metabolism; Nucleotide Motifs; Poly dA-dT / metabolism; Transcription Factors / genetics; Transcription Factors / metabolism; Transcription Factors / physiology
topics (OpenAlex): Plant Molecular Biology Research; Genomics and Chromatin Dynamics; Plant nutrient uptake and metabolism
TL;DR:
This work uses tiling microarrays to map S/MARs on Arabidopsis chromosome 4, found to be spaced more closely than in the large plant and animal genomes studied to date and preferentially enriched in poly(dA:dT) tracts, sequences that resist nucleosome formation.
