Evolution and role of neo-sex chromosomes in mitonuclear co-evolution

该项目旨在描述澳大利亚鸟类中新的、延伸的性染色体的进化，然后阐明它们在与气候相关的适应性进化中的作用。该物种分为两个谱系，分别携带不同的线粒体基因组和性染色体上携带的核编码线粒体基因。该项目旨在测试这种非同寻常的基因组安排是否将物种分裂为两种形式：一种适应更炎热、更干燥的环境，另一种适应更温和的环境。这将使用基因组学、细胞遗传学和代谢数据的创新组合来解决。了解起作用的机制将代表着生态学和进化方面的重大进展，并可能对保护管理产生影响。

This project aims to characterize the evolution of novel, extended sex chromosomes in an Australian bird, then elucidate their role in climate-associated adaptive evolution. The species falls into two lineages bearing distinct mitochondrial genomes and nuclear-encoded mitochondrial genes carried on sex chromosomes. The project aims to test whether this extraordinary genome arrangement is splitting the species into two forms: one adapted to hotter, drier environments, one to milder ones. This would be tackled using an innovative combination of genomics, cytogenetics, and metabolic data. Understanding the mechanisms at play would represent a major advance in ecology and evolution, with potential implications for conservation management.
