Research Interests For more detailed research information, see the Borevitz Lab Website.
Genetics of local adaptation in plants
Specific
interests of the lab include the genetics of adaptation to seasonal
light environments. Quantitative and population genetic approaches in
Arabidopsis thaliana, Arabidopsis lyrata, Aquilegia (columbines), and
switchgrass are used to dissect local and regional phenotypic
variation. What genes and what alleles explain differential survival
(germination/elongation) and reproduction (flowering time) in the
field? Are these new variants or new combinations of existing
polymorphisms? Are similar evolutionary steps occurring in related
species living in a similar ecological context? Environmental variation in growth chambersgrowth chambers
Genetic variation in environmental response
In
Arabidopsis, we have revealed extensive genetic variation in world-wide
collections for seedling elongation (Nature Genetics 2001) and
flowering time (Genetics 2005) under unique light environments and
determined quantitative trait loci (QTL) responsible for this variation
(Genetics 2002,2004, PLoSONE, 2007). The next questions are what are
the genes underlying these QTL and what are the functional allelic
differences? How have the patterns of variation at these loci been
shaped by natural selection? Can we find evidence for local adaptation
and determine the ecological environmental differences driving
selection? Microarray analysis of genetic variationarray mapping
Genomic approaches to natural variation
A
second focus is on the development of genomics methods to enable
comprehensive studies of natural variation. Tools such as whole genome
oligo-nucleotide SNP tiling arrays are being used for very high
resolution studies of polymorphism, mapping (Genome Research 2003,
Genetics 2004, PNAS 2005, Plant Phys 2005, COPB 2007) and haplotype
analysis (PNAS 2007). These arrays which interrogate nearly every base
of the A. thaliana genome, can reveal natural variation in gene or
allelic expression and alternative splicing to identify candidate genes
for QTL and their downstream responses (Annual Review 2004). SNPs,
novel Single Feature Polymorphisms (SFPs) and CNPs can identify
potential causative changes for QTL. We have also revealed natural
variation in methylation by differential enzyme digestion followed by
tiling array hybridization. Little Bluestem (Northerly Island)
From molecular systems to ecosystems: restoring biodiversity and biomass
We
use genomic profiling of RNA and methylation variation to understand
cellular signaling pathways and their genetic control. These
responses are the integration of environmental inputs through
development resulting in altered organismal phenotypes of the adult
plant. Whole plant structure and physiology affects the species
community makeup and higher order inter-specific interactions.
The resulting landscape effects, in turn have outputs measured as
ecosystems services including biomass for biofuel, habitat for
biodiversity, and carbon and nitrogen sequestration that input again on
molecular cellular signaling.
