Contact zone of two different chloroplast lineages and genetic guidelines for seed transfer in Quercus serrata and Q. crispulaKataru Onosato, Takuto Shitara, Asako Matsumoto, Ayumi Matsuo, Yoshihisa Suyama & Yoshihiko Tsumura
Within their natural distribution ranges, plant species exhibit genetic structure which has been created by global climate change and natural selection over long periods. To conserve local forests with different genetic structures, genetic guidelines for seed and seedling transfer in individual species are therefore necessary. Genetic guidelines have been published for 43 Japanese tree species using population genetic data; however, for practical use, more detailed genetic borders between important genetic lineages should be clarified to...
Spatial, climate and ploidy factors drive genomic diversity and resilience in the widespread grass Themeda triandraCollin Ahrens, Elizabeth A. James, Adam D. Miller, Ferguson Scott, Nicola C. Aitken, Ashley W. Jones, Patricia Lu‐Irving, Justin O. Borevitz, David J. Cantrill & Paul D. Rymer
This data set was used to assess the climate resilience of Themeda triandra, a foundational species and the most widespread plant in Australia, by assessing the relative contributions of spatial, environmental, and ploidy factors to contemporary genomic variation. Reduced-representation genome sequencing on 472 samples from 52 locations was used to test how the distribution of genomic variation, including ploidy polymorphism, supports adaptation to hotter and drier climates.
