Protein synthesis can be regulated with respect to changing environmental cues via the deposition of chemical modifications into rRNA. Here, we present the structure of a plant ribosome from tomato and a quantitative mass spectrometry analysis of its rRNAs. The study reveals fine features of the ribosomal proteins and 71 plant-specific rRNA modifications, and it re-annotates 30 rRNA residues in the available sequence. At the protein level, isoAsp is found in position 137 of uS11, and a zinc finger previously believed to be universal is missing from eL34, suggesting a lower effect of zinc deficiency on protein synthesis in plants. At the rRNA level, the plant ribosome differs markedly from its human counterpart with respect to the spatial distribution of modifications. Thus, it represents an additional layer of gene expression regulation, highlighting the molecular signature of a plant ribosome. The results provide a reference model of a plant ribosome for structural studies and an accurate marker for molecular ecology.", "doi": "10.1016/j.xplc.2022.100342", "pmid": "35643637", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC9483110"}, {"db": "pii", "key": "S2590-3462(22)00097-9"}], "notes": [], "created": "2026-08-21T11:31:07.560Z", "modified": "2026-08-21T11:31:07.586Z"}, {"entity": "publication", "iuid": "6042e644c1ff4c789015ca158cf57e6e", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/6042e644c1ff4c789015ca158cf57e6e.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/6042e644c1ff4c789015ca158cf57e6e"}}, "title": "Demographic Processes Linked to Genetic Diversity and Positive Selection across a Species' Range.", "authors": [{"family": "Willi", "given": "Yvonne", "initials": "Y"}, {"family": "Fracassetti", "given": "Marco", "initials": "M"}, {"family": "Bachmann", "given": "Olivier", "initials": "O"}, {"family": "Van Buskirk", "given": "Josh", "initials": "J"}], "type": "journal article", "published": "2020-11-09", "journal": {"title": "Plant Commun", "issn": "2590-3462", "volume": "1", "issue": "6", "pages": "100111", "issn-l": null}, "abstract": "Demography determines the strength of genetic drift, which generally reduces genetic variation and the efficacy of selection. Here, we disentangled the importance of demographic processes at a local scale (census size and mating system) and at a species-range scale (old split between population clusters, recolonization after the last glaciation cycle, and admixture) in determining within-population genomic diversity and genomic signatures of positive selection. Analyses were based on re-sequence data from 52 populations of North American Arabidopsis lyrata collected across its entire distribution. The mating system and range dynamics since the last glaciation cycle explained around 60% of the variation in genomic diversity among populations and 52% of the variation in the signature of positive selection. Diversity was lowest in selfing compared with outcrossing populations and in areas further away from glacial refugia. In parallel, reduced positive selection was found in selfing populations and in populations with a longer route of postglacial range expansion. The signature of positive selection was also reduced in populations without admixture. We conclude that recent range expansion can have a profound influence on diversity in coding and non-coding DNA, similar in magnitude to the shift toward selfing. Distribution limits may in fact be caused by reduced effective population size and compromised positive selection in recently colonized parts of the range.", "doi": "10.1016/j.xplc.2020.100111", "pmid": "33367266", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC7747977"}, {"db": "pii", "key": "S2590-3462(20)30142-5"}], "notes": [], "created": "2026-08-21T11:31:05.499Z", "modified": "2026-08-21T11:31:05.553Z"}], "created": "2026-08-21T11:31:05.513Z", "modified": "2026-08-21T11:31:05.513Z"}
