Summary

Recent advance in genomics are generating tremendous amounts of data. As a result, the field of bioinformatics confronts an unprecedented need to move towards greater interdisciplinary to better interpret and understand these data. The goal of our research is to understand the molecular underpinnings of various plant adaptations to semi-arid and arid environments through genomics-enabled bioinformatics approaches. Our research focuses broadly on comparative genomics and gene expression from the perspectives of genomics, systems biology, and bioinformatics. We propose to undertake integrative approaches that span multiple levels of biological organization from the genome to the metabolome.

The Yim’s lab is worked on plant genomics, studying how genomes are organized and how genome structure affects gene expression, phenotypes, and genomic plasticity. We use of bioinformatics to address questions in plant diversity, with an emphasis on enabling crop improvement efforts though through diversification mechanisms associated with large scale genome duplications, while at the same time maintaining core functions. The major objectives of our lab include developing strategies for increased plant tolerance to harsh environments and increased biomass productivity through understanding the basis of polyploidy and genome conformation in plants.

Our on-going research projects include de novo assembly and analysis of multiple genomes and transcriptomes. We participate in a variety of open source software development projects and in other efforts to facilitate data sharing and improving adherence to standards among groups involved in information resource management in plant biology.

Lastly, our lab seeks to illuminate the processes regulating development, metabolomics, protein structure, evolution analysis and photosynthesis and will enable future attempts to characterize gene function in plants, insects and vertebrates.

Mitochondrial haplotypes are not associated with mice selectively bred for high voluntary wheel running
Mitochondrial haplotypes have been associated with human and rodent phenotypes, including nonshivering thermogenesis capacity, learning capability, and disease risk. Although the mammalian mitochondrial D-loop is highly polymorphic, D-loops in laboratory mice are identical, and variation occurs elsewhere mainly between nucleotides 9820 and 9830. Part of this region codes for the tRNAArg gene and is associated with mitochondrial densities and number of mtDNA copies. We hypothesized that the capacity for high levels of voluntary wheel-running behavior would be associated with mitochondrial haplotype. Here, we analyzed the mtDNA polymorphic region in mice from each of four replicate lines selectively bred for 54 generations for high voluntary wheel running (HR) and from four control lines (Control) randomly bred for 54 generations. Sequencing the polymorphic region revealed a variable number of adenine repeats. Single nucleotide polymorphisms (SNPs) varied from 2 to 3 adenine insertions, resulting in three haplotypes. We found significant genetic differentiations between the HR and Control groups (Fst?=?0.779, p?=?0.0001), as well as among the replicate lines of mice within groups (Fsc?=?0.757, p?=?0.0001). Haplotypes, however, were not strongly associated with voluntary wheel running (revolutions run per day), nor with either body mass or litter size. This system provides a useful experimental model to dissect the physiological processes linking mitochondrial, genomic SNPs, epigenetics, or nuclear-mitochondrial cross-talk to exercise activity.
