与物种组成不同的生态群落一样,真核生物基因组所包含的转座因子(TE)的数量和多样性也不同。由于TE对其宿主物种的生物学有相当大的影响,我们需要更好地了解它们的动态是否反映了某种形式的组织或主要由随机过程驱动。在这里,我们借用物种多样性的生态概念,探讨TE之间的相互作用如何有助于结构TE社区内的基因组生态系统。而生态位理论预测一个稳定的多样性TE,因为他们的分歧的特点,生物多样性的中性理论预测TE社区的组装随机过程中发挥作用的个人TE的水平。然而,与生态群落相反,TE群落是在其生态系统水平上通过选择形成的,即,个人主机因此,开发特定于基因组的生态模型将是模拟TE动态的先决条件。
Like ecological communities, which vary in species composition, eukaryote genomes differ in the amount and diversity of transposable elements (TEs) that they harbor. Because TEs have a considerable impact on the biology of their host species, we need to better understand whether their dynamics reflects some form of organization or is primarily driven by stochastic processes. Here we borrow ecological concepts on species diversity to explore how interactions between TEs can contribute to structure TE communities within their genomic ecosystem. Whereas the niche theory predicts a stable diversity of TEs because of their divergent characteristics, the neutral theory of biodiversity predicts the assembly of TE communities from stochastic processes acting at the level of individual TE. Contrary to ecological communities, however, TE communities are shaped by selection at the level of their ecosystem, i.e., the host individual. Developing ecological models specific to the genome will thus be pre-requisite for modeling the dynamics of TEs.
