1Trans-generational effects in the clonal invader Alternanthera philoxeroides显示文摘近年的研究已经揭示出表型可塑性可以通过营养世代遗传。从这个意义上讲,环境诱导的基因调控变化(例如DNA甲基化,即表观遗传变异)会导致可逆的塑性反应传递给后代。这种跨世代的可塑性在克隆植物中尤其重要,因为有性繁殖减少会降低通过遗传变异进行适应的可能性。许多最具侵略性的植物入侵者都具有克隆性,而且克隆性被认为是植物入侵性的关键。本研究中,我们的目标是确定在克隆入侵者喜旱莲子草(Alternanthera philoxeroides)中是否发生了跨代效应,以及这种效应在本地和非本地群落之间是否存在差异。在同质园实验中,我们将采自巴西(原产地)和伊比利亚半岛(非原产地)的喜旱莲子草种群分别种植在养分高和低的土壤中,后代植株被移植到高养分条件下作为对照。为了检验DNA甲基化对跨代可塑性的潜在作用,一半的母株用去甲基化剂5-氮杂胞苷处理。在来自原产地和非原产地的种群中均观察到了跨代效应。有趣的是,在原产地种群的生长变量(分株数、茎生物量、根生物量和总生物量)中发现了跨代效应,而在非原产地种群中发现了生物量分配具有跨代效应。在原产地种群中出现的跨代效应可以用“银勺”效应来解释,而非原产地种群的跨代效应可以归因于DNA甲基化引起的表观遗传传递。本研究强调了跨代效应对克隆植物生长的重要性,这有助于理解众多克隆植物能够成功繁殖扩张的机制。Rubén Portela Bi-Cheng Dong Fei-Hai Yu Rodolfo Barreiro Sergio R.Roiloa Dalva MSilva Matos 2020Journal of Plant Ecology2020,13,1:2
