Transgenerational plasticity (TGP) refers to the influence of ancestral environmental signals on offspring's traits across generations. While evidence TGP in plants is growing, its role plant adaptation over successive generations remains unclear, particularly floating facing fluctuating environments. Duckweed (

Transgenerational plasticity (TGP) occurs when maternal environments influence the expression of traits in offspring, and some cases may increase fitness offspring have evolutionary significance. However, little is known about extent environment on gene its relationship with trait variations across generations. In this study, we examined TGP field pennycress (Thlaspi arvense) response to cadmium (Cd) stress. first generation, along soil Cd concentration, total biomass, individual height, number seeds significantly decreased, whereas time flowering, superoxide dismutase (SOD) activity, content reduced glutathione increased. Among these traits, only SOD activity showed a significant effect TGP; Cd-treated individuals maintained high absence According results RNA sequencing bioinformatic analysis, 10,028 transcripts were identified as Cd-responsive genes. them, 401 transcriptional memory genes (TMGs) that same pattern under normal conditions second generation parents generation. These mainly participated tolerance-related processes such oxidative stress, cell wall biogenesis, abscisic acid signaling pathways. The weighted correlation network analysis modules correlated recruited more TMGs than other traits. SOD-coding CSD2 was found one activity. Furthermore, several co-expressed hub highly connected nodes critical network's topology; therefore, recruitment potentially related TGP. findings indicated that, generations, played an important role Moreover, provided new insights into evolution mediated by phenotypic plasticity.

In variable environments, phenotypic plasticity can increase fitness by providing tight environment-phenotype matching. However, adaptive is expected to evolve only when the future selective environment be predicted based on prevailing conditions. That is, juvenile should predictive of adult (within-generation plasticity) or parental offspring (transgenerational plasticity). Moreover, environmental predictability also shape transient responses such as stress response in an direction. Here, we test links between and evolution combining time series analyses a common garden experiment using temperature stressor temperate butterfly (

Abstract Trade‐offs among traits are central to life‐history theory and often closely linked an organism's fitness. Understanding how these trade‐offs vary populations across environments is therefore important more accurately predict species' responses future climate change. However, the extent which remains unknown because few studies investigate intraspecific differences. We performed a full‐factorial split‐brood common garden experiment test variation in rearing temperature affects developmental timing other for survival during diapause Glanville fritillary butterfly ( Melitaea cinxia ). Pre‐diapause larvae originating from four regions latitudinal cline Europe were reared at temperatures (25, 28, 31 34°C), we used reaction norm approach evidence of genetic differentiation plasticity regions. found clear signs multiple traits, as well differences plasticity. Northern entered fourth instar when low, whereas southern did so fifth instar. As result, development time canalized with regards northern larvae: due entering one stage earlier, they develop fast even cold, always slower, especially low temperatures. trade‐off, have lower body mass cooler compared larvae, show increased mass.
