“…Significant transgenerational effects detected in this study are in line with general expectation that such effects may be important for species performance in general (e.g., Guillaume et al., ; Herman & Sultan, ). The fact that we demonstrated these effects in clonal species adds to current growing body of the literature, suggesting that transgenerational plasticity may not only be important factor affecting performance of generatively reproducing species, but may be also important in clonal species (González, Dumalasová, Rosenthal, Skuhrovec, & Latzel, ; Gonzalez et al., ; Latzel & Klimesova, ).…”

In spite of the increasing number of studies on the importance of transgenerational plasticity for species response to novel environments, its effects on species ability to respond to climate change are still largely unexplored. We study the importance of transgenerational plasticity for response of a clonal species Festuca rubra. Individuals from four natural populations representing two levels of temperature and two levels of precipitation were cultivated in four growth chambers that simulate the temperature and precipitation of origin of the populations (maternal phase). Each population was represented in each growth chamber. After 6 months, single young ramets of these plants were reshuffled among the growth chambers and let to grow for additional 2 months (offspring phase). The results show that transgenerational effects (i.e., maternal phase conditions) significantly modify species response to novel climates, and the direction and intensity of the response depend on the climate of origin of the plants. For traits related to recourse acquisition, the conditions of maternal phase, either alone or in interaction mainly with climate of origin, had stronger effect than the conditions of cultivation. Overall, the maternal climate interacted more intensively with the climate of origin than with the offspring climate. The direction of the effect of the maternal climate was of different directions and intensities depending on plant origin and trait studied. The data demonstrated strong significant effects of conditions during maternal phase on species response to novel climates. These transgenerational affects were, however, not adaptive. Still, transgenerational plasticity may be an important driver of species response to novel conditions across clonal generations. These effects thus need to be carefully considered in future studies exploring species response to novel climates. This will also have strong effects on species performance under increasingly variable climates expected to occur with the climate change.

“…Few previous studies have explored the effects of foliar herbivory on rhizomes of vegetatively spreading plants (but see Gómez et al 2007Gómez et al , 2010Dong et al 2017;González et al 2017), and none have demonstrated the ability of clonal plants to transmit herbivoreinduced information from parental plants to unconnected offshoots. The current results demonstrate that information concerning plant herbivory can persist in unconnected offshoots grown from rhizomes of S. carolinense, which have never experienced herbivory, and that this information positively influences offshoot defenses against herbivores and negatively impacts herbivore (M. sexta) performance traits (Table 1).…”

Herbivory and inbreeding affect growth, reproduction, and resistance in the rhizomatous offshoots of Solanum carolinense (Solanaceae)

Resource sharing within clonal plant networks can occur via the translocation of water, nutrients, and photoassimilates through rhizomes and stolons. Similar mechanisms may mediate the sharing of information (e.g., about herbivory or other environmental stressors) among ramets via molecular or biochemical signals. The storage of such information in belowground structures could facilitate the transmission of appropriate phenotypic responses across growing seasons in perennial species. However, few previous studies have explored the potential transfer of ecologically relevant information within such networks. This study addresses the effects of foliar herbivory and belowground overwintering on the growth and flowering, physical defenses, and herbivore resistance in the clonally spreading species Solanum carolinense L. (Solanaceae). We used rhizomes from inbred and outbred plants that were repeatedly exposed to feeding damage by Manduca sexta L. (Sphingidae) caterpillars and rhizomes from undamaged control plants. These rhizomes were either planted immediately or exposed to overwintering conditions and allowed to produce new ramets (rhizomatous offshoots). We then assessed offshoot emergence, flowering, physical defense traits, and herbivore performance. Relative to controls, offshoots of herbivore-damaged plants exhibited greater spine and trichome densities, and reduced performance of M. sexta larvae. However, they also emerged and flowered significantly later, and produced fewer flowers than offshoots of undamaged plants. Inbreeding also negatively affected offshoot emergence, flowering, trichome production, and herbivore resistance. These effects of parental herbivory were more pronounced in outbred offshoots, indicating that inbreeding may compromise the trans-seasonal induction of plant defenses. Finally, exposure to overwintering conditions increased trichome production and reduced caterpillar performance on offshoots. Together, these results show that induced defenses can be transmitted through rhizomes and affect offshoot growth, flowering, defensive traits, and herbivore resistance. They also document fitness-related costs associated with defense induction in offshoots and suggest that the transfer of defenses across seasons can be compromised by inbreeding.

“…Further, this hypomethylation response was stable over long time periods in poplar trees, supporting the notion that epigenetic changes contribute to resilience to long‐term drought stress. Vítek Latzel (Institute of Botany of the Czech Academy of Sciences, Czech Republic) presented a drought study in the clonal herbaceous plant Trifolium repens , indicating that varying levels and time periods of drought might determine whether epigenetic variation contributes to the stress response (González et al ., ). Together, these studies suggest that short‐term stress under controlled conditions might not result in the same epigenetic signatures as long‐term exposure to natural environments.…”
