Changes in gene expression as a climate adaptation mechanism in plants
During evolution, the coding sequence of genes evolves slower than their expression patterns, therefore transcriptional regulation is critical for rapid adaptation to new environments. Understanding the adaptation mechanisms of plants is important in agriculture and in natural populations. Studying evolution-driven transcriptome changes that allow plants to adapt to new climates and ecological niches requires a large amount of natural variability information. Funded by the Marie Skłodowska-Curie Actions programme, the TxnEvoClim project will use genomic and transcriptomic data from the Arabidopsis thaliana 1001 Genomes project, measurements of gene expression under water deprivation, and data on gene regulation and field fitness to understand how gene expression is shaped by climate and the genetic potential to adapt to new environments.
