The dataset consists of three comma-delimited plain text files corresponding to (i) Epigenotypic data of maternal modules, (ii) phenotypic data of maternal modules, and (iii) phenotypic data of the subprogenies obtained in the greenhouse, for different modules from adult, wild-grown, field-sampled plants of the shrub Lavandula latifolia (Lamiaceae). Five modules, each consisting of a terminal branchlet bearing one inflorescence and its subtending leaves, were collected from each of 15 wild-growing L. latifolia plants from a large population growing near Arroyo Aguaderillos in the Sierra de Cazorla (Jaén province, southeastern Spain; geographical coordinates 37.96157 N, 2.88389 W). Each module was characterized epigenotypically by the methylation state of methylation-sensitive amplified fragment length polymorphism markers (MS-AFLP), and phenotypically by fecundity-related traits (inflorescence length, and size, number and mass of seeds produced). Seeds from the different modules were sown in the greenhouse and resulting ‘subprogenies’ characterized phenotypically (germination probability and time to emergence, seedling size, susceptibility to fungal disease). For MS-AFLP data, each column refer to a specific (although anonymous) marker, identified by primer combination and size (base pairs)., This dataset includes three files containing (i) Epigenotypic data of maternal modules, (ii) phenotypic data of maternal modules, and (iii) phenotypic data of greenhouse subprogenies for different modules of 15 adult, wild-grown, field-sampled plants of the shrub Lavandula latifolia., Partial support for this study was provided by grants PID2019-104365GB-I00 (Ministerio de Ciencia e Innovación, Spanish Government) and P18-FR-4413 (Consejería de Transformación Económica, Industria, Conocimiento y Universidades, Andalusian Government)., Five modules, each consisting of a terminal branchlet bearing one inflorescence and its subtending leaves, were collected from each of 15 wild-growing L. latifolia plants from a large population growing near Arroyo Aguaderillos in the Sierra de Cazorla (Jaén province, southeastern Spain; geographical coordinates 37.96157 N, 2.88389 W).

Ecological significance of intraplant variation: epigenetic mosaicism in Lavandula latifolia plants predicts extant and transgenerational variability of fecundity-related traits. Journal of Ecology (in press)., Peer reviewed

In flowering plants, pollinators contribute to gene flow while they also respond to variation in plant traits together determined by genetic, epigenetic and environmental sources of variation. Consequently, a correlation between abundance and diversity of pollinators and the genetic and epigenetic characteristics of plant populations such as diversity or distinctiveness is expected. However, no study has explored these long-term dimensions of plant–pollinator interactions. Mediterranean narrow endemics often exhibit unexpectedly high levels of population genetic and epigenetic diversity. We hypothesize that pollinators may contribute to explain this pattern. Specifically, given the higher sensitivity of small, isolated population to gene flow, we expect a stronger association of pollinators with population genetic and epigenetic variability in narrow endemics than in widely distributed congeners. We studied five pairs of congeneric plant species, consisting of one narrow endemic with a restricted distribution and one widespread congener, found in the Sierra de Cazorla mountains (SE Spain). We characterized the pollinators in up to three populations per species to estimate their diversity and visitation rates. Additionally, we calculated the genetic and epigenetic diversity and distinctiveness of each population using AFLP markers and methylation-sensitive AFLP markers (MSAP), respectively. We assessed the relationship between pollinator diversity and visitation rates. The diversity of pollinators did not vary according to the plant´s distribution range, but visitation rate was higher in widespread species. As predicted, only narrow endemics showed a significant association between pollinators and their population genetic and epigenetic characteristics. Specifically, higher pollinator diversity and visitation rates entailed higher population genetic diversity and lower epigenetic distinctiveness. This work shows the importance of investigating the relationship between pollinator diversity and population genetics and epigenetics to better understand the evolution of plant rarity., Junta de Andalucía : P18-FR-4413; Consejería de Innovación Ciencia y Empresa
