摘 要：Aims Recent studies have revealed heritable phenotypic plasticity through vegetative *** this sense,changes in gene regulation induced by the environment,such as DNA methylation(*** changes),can result in reversible plastic responses being transferred to the offspring *** trans-generational plasticity is expected to be especially relevant in clonal plants,since reduction of sexual reproduction can decrease the potential for adaptation through genetic *** of the most aggressive plant invaders are clonal,and clonality has been suggested as key to explain plant *** we aim to determine whether trans-generational effects occur in the clonal invader Alternanthera philoxeroides,and whether such effects differ between populations from native and non-native *** In a common garden experiment,parent plants of *** from populations collected in Brazil(native range)and Iberian Peninsula(non-native range)were grown in high and low soil nutrient conditions,and offspring plants were transplanted to control conditions with high *** test the potential role of DNA methylation on trans-generational plasticity,half of the parent plants were treated with the demethylating agent,*** Findings Trans-generational effects were observed both in populations from the native and the non-native ***,trans-generational effects occurred on growth variables(number of ramets,stem mass,root mass and total mass)in the population from the native range,but on biomass partitioning in the population from the non-native ***-generational effects of the population from the native range may be explained by a‘silver-spoon’effect,whereas those of the population from the non-native range could be explained by epigenetic transmission due to DNA *** study highlights the importance of trans-generational effects on the growth of a clonal plant,which could help to understand
