We study the population genetics process of adaptation in natural plant populations, using state of the art techniques in a handful of model organisms. We ask questions such as, how are populations shaped by their local environment? What traits are under selection? What are the genetic loci underlying these traits? Are alleles at these loci filtered by environmental gradients on the landscape over and above background genomic differentiation? Ultimately alleles at adaptive loci in foundation species may have an extended phenotype and determine ecosystem properties and services?
High throughput genome sequencing allows us to use Genome Wide Association Studies to determine the causative alleles and fine patterns population structure associated with adaptive trait variation. It also allows Landscape Genomic studies to determine the spatial and temporal variation of alleles at adaptive and neutral loci across environmental gradients.
Another critical tool is high resolution phenotyping by insitu imaging. These Phenomic studies are being performed on mapping populations in climate chambers to quantify growth (photosynthesis), development (photomorphogenesis), and reproduction (fitness) in real time throughout the growing season.
The Borevitz lab studies the genetic basis of adaptation in natural plant populations, spanning model organisms, foundation species and emerging crops. We develop and use Genomic and Phenomic tools for association studies in controlled climate chambers and on the landscape. Population genomics is used to map adaptive alleles and genetic structure. Phenomics is used to capture growth, development, and yield traits throughout the growing season. These studies connect genotype to phenotype and environment with the aim to better manage lands and regenerate life supporting services. Live and work in Canberra!
The Borevitz lab plays a key role in the Australian Research Council Centre of Excellence in Plant Energy Biology (PEB), a cutting edge research centre focused on better understanding the way in which plants interconvert forms of chemical energy in response to environmental change. PEB’s vision is to enhance plant energy efficiency by simultaneously optimising energy capture, conversion and use in changing environments to improve the sustainable productivity of plants.
