Meiotic recombination is a key source of the genetic variation upon which evolution thrives. This project aims to exploit new genomic resources to provide the first detailed study of recombination in Australia’s iconic Eucalypts and clarify its evolutionary role. This project will study: variation in the rate of recombination along the 11 Eucalypt chromosomes, and determine genome features which are associated with ‘hotspots’ and ‘coldspots’ of recombination; the patterns of variation in recombination rate between species, genotypes, sexes and chromosomes; and, whether the environment and population history affect recombination and thus evolvability of natural populations.

减数分裂重组是促进进化的遗传变异的关键来源。该项目旨在开发新的基因组资源，提供澳大利亚标志性桉树重组的第一个详细研究，并阐明其进化作用。该项目将研究：沿11条桉树染色体的重组率变异，并确定与重组的“热点”和“冷点”相关的基因组特征；物种间、基因型间、性别间和染色体间重组率的变异规律；环境和种群历史是否影响自然种群的重组和进化。
