Caloric restriction-mediated reproductive lifespan extension across multiple strains of the clonal aquatic plant <em>Lemna turionifera</em>

Lifespan extension due to caloric restriction (CR) is a well-established aspect of animal senescence that has been observed in many taxa. Contrastingly, there is much less evidence in plants, even though it is straightforward to manipulate CR by restricting photosynthesis through reduction in light intensity. One of the few studies to report CR-mediated plant lifespan extension investigated reproductive lifespan in a single strain of the duckweed Lemna minor, a tiny, floating, aquatic plant. Here, with an aim of beginning to test the generality of this phenomenon in plants, we considered a congeneric species, L. turionifera, and examined CR-mediated lifespan extension in eight strains collected from Alberta, Canada. We grew plants in the lab under axenic conditions, and manipulated light intensity (and hence, putatively, CR) with neutral density filters. Plants that grew under dimmer conditions had longer reproductive lifespans, on average, than those that grew under brighter conditions..., , # Data from: Caloric restriction-mediated reproductive lifespan extension across multiple strains of the clonal aquatic plant *Lemna turionifera* Dataset DOI: [10.5061/dryad.rv15dv4n7](https://doi.org/10.5061/dryad.rv15dv4n7) ## Description of the data and file structure There are two data files (.csv) and one code file (.r): \"CR_strains_daily_reproduction_2025_03_08.csv\" contains daily reproduction data for *Lemna turionifera* plants in our experiment \"CR_strains_temperature_2025_03_08.csv\" contains temperature data for our experimental setup under bright light and dim light conditions \"CR_strains_analysis_2025_11_21.r\" contains R code for data analysis ### Files and variables #### File: CR_strains_daily_reproduction_2025_03_08.csv **Description:**Â Data file associated with our daily reproduction observations (see main text in our article).
