Other aspects of reproductive costs remain poorly understood, including ecological costs of reproduction, the fitness effects of reproductive trade-offs involving growth or physiological processes, and how the male sex role influences reproductive costs.

This material represents not only a repository of plant genetic resources but also an asset for nature-based solutions (NbS), such as ecological restoration and reforestation, and research in plant science. Here, we explore the temporal and spatial dimensions of seed collections and the challenges limiting their use in NbS and research, while highlighting how they could be a source of material for adaptation and evolution studies. However, existing seed lots originally collected for conservation purposes will not be sufficient to support NbS and research on their own. We propose a long-term experimental approach that, together with new targeted collecting programmes, can leverage the temporal dimension of seed collections by carrying out repeated sampling from the same population. At the same time, we stress how these approaches will benefit from new dedicated collections holding seeds from each maternal line separately. By moving towards a bidimensional (space and time) collecting approach, conservation seed banks can go beyond long-term conservation per se and transform their collections into dynamic repositories capable of addressing pressing ecological, evolutionary, and conservation questions and help to understand and shape plant communities of the future.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"39 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DNA repeats can be seen both in coding and in noncoding regions of the genome. Due to the recurring nature of the sequences, simple DNA repeats tend to be more prone to errors during replication and repair, resulting in variability in their unit length. This feature of simple sequence repeats led to their use as molecular markers for mapping traits in diverse organisms. Advances in genomics, and the ever-reducing costs of genome sequencing have empowered us to assess the functional impacts of DNA repeats. The variability in repeat lengths can cause phenotypic differences depending on where they are present in the genome. Variability in the repeat length in coding regions of genes results in poly amino acid stretches that appear to interfere with protein function, including the perturbation of protein–protein interactions with diverse phenotypic impacts. These are often common allelic variations that can significantly impact evolutionary dynamics. In extreme situations, repeats can undergo massive expansions and appear as outliers. Repeat expansions underlie several genetic defects in plants to diseases in humans. This review systematically analyses tandem DNA repeats in plants, their role in development and environmental response and adaptation in plants. We identify and synthesise emerging themes, differentiate repeat length variability and repeat expansions, and argue that many repeat-associated phenotypes in plants are yet to be discovered. We emphasise the underexplored nature and immense potential of this area of research, particularly in plants, and suggest ways in which this can be achieved and how it might contribute to evolution and agricultural productivity.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"137 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
