项目摘要

Genetic differences as the basis for selection and evolution in all organisms is well documented, while the role of epigenetic diversity is more hypothesized than experimentally proven. The essential insights into epigenetic mechanisms gained in plant science let it appear obvious to address the questions, (1) whether and how information outside of the DNA sequence can influence phenotype and fitness and (2) if environmental factors can change epigenetic features and generate epialleles.The proposed Collaborative Research Project was developed by five European experts in epigenetic, ecological and ecogenomic research. They will join forces, using their established methodology, to deliver proof of concept for the role of epigenetics in plant adaptation to environmental change. Work with the inbreeding species Arabidopsis thaliana, with a plethora of genetic, epigenetic and genomic information and available in numerous accessions from different habitats, will be complemented by experiments with Scabiosa columbaria, an outbreeding species for which consequences of habitat fragmentation and inbreeding depression are well documented. Well characterized plant material will be analyzed for epigenetic diversity, subjected to controlled environmental conditions and studied in subsequent generations. Epigenetic analysis will comprise DNA methylation and chromatin modifications on individual sequences as well as whole genomes.The project is expected to result in a better understanding of the extent, significance and generality of epigenetic variation as an additional mechanism for plant adaptation. In the light of significant environmental changes in close future, it might help increasing the weight of European research in this field.
遗传差异是所有生物体选择和进化的基础,这是有据可查的,而表观遗传多样性的作用更多的是假设而不是实验证明。在植物科学中获得的对表观遗传机制的基本见解使解决以下问题变得显而易见:(1)DNA序列之外的信息是否以及如何影响表型和适合度;(2)环境因素是否可以改变表观遗传特征并产生表观等位基因。拟议的合作研究项目由五位欧洲表观遗传、生态学和生态基因组学研究专家开发。他们将联合起来,利用他们建立的方法,为表观遗传学在植物适应环境变化中的作用提供概念证明。与近亲繁殖物种拟南芥的工作,与大量的遗传,表观遗传和基因组信息,并在许多加入来自不同的栖息地,将补充实验Scabiosa columbaria,一个远系繁殖物种的栖息地破碎化和近亲繁殖衰退的后果是有据可查的。将对表征良好的植物材料进行表观遗传多样性分析,并在受控的环境条件下进行后续世代研究。表观遗传分析包括个别序列及整个基因组的DNA甲基化及染色质修饰,预期该项目有助加深了解表观遗传变异作为植物适应的另一机制的程度、意义及普遍性。鉴于在不久的将来会发生重大的环境变化,这可能有助于增加欧洲在这一领域的研究。
