In Vivo Quantification Reveals Extensive Natural Variation in Mitochondrial Form and Function in Caenorhabditis briggsae

Creator:: Hicks, Kiley A., Howe, Dana K., Leung, Aubrey, Denver, Dee R., and Estes, Suzanne
Abstract:: In We have analyzed natural variation in mitochondrial form and function among a set of Caenorhabditis briggsae isolates known to harbor mitochondrial DNA structural variation in the form of a heteroplasmic nad5 gene deletion (nad5 Delta) that correlates negatively with organismal fitness. We performed in vivo quantification of 24 mitochondrial...

Evolution of a Higher Intracellular Oxidizing Environment in Caenorhabditis elegans under Relaxed Selection

Creator:: Joyner-Matos, Joanna, Hicks, Kiley A., Cousins, Dustin, Keller, Michelle, Denver, Dee R., Baer, Charles F., and Estes, Suzanne
Abstract:: We explored the relationship between relaxed selection, oxidative stress, and spontaneous mutation in a set of mutation-accumulation (MA) lines of the nematode Caenorhabditis elegans and in their common ancestor. We measured steady-state levels of free radicals and oxidatively damaged guanosine nucleosides in the somatic tissues of five MA lines for...

Selfish Little Circles: Transmission Bias and Evolution of Large Deletion-Bearing Mitochondrial DNA in Caenorhabditis briggsae Nematodes

Creator:: Clark, Katie A., Howe, Dana K., Gafner, Kristin, Kusuma, Danika, Ping, Sita, Estes, Suzanne, and Denver, Dee R.
Abstract:: Selfish DNA poses a significant challenge to genome stability and organismal fitness in diverse eukaryotic lineages. Although selfish mitochondrial DNA (mtDNA) has known associations with cytoplasmic male sterility in numerous gynodioecious plant species and is manifested as petite mutants in experimental yeast lab populations, examples of selfish mtDNA in animals...

High-Density SNP Genotyping of Tomato (Solanum lycopersicum L.) Reveals Patterns of Genetic Variation Due to Breeding

Creator:: Sim, Sung-Chur, Van Deynze, Allen, Stoffel, Kevin, Douches, David S., Zarka, Daniel, Ganal, Martin W., Chetelat, Roger T., Hutton, Samuel F., Scott, John W., Gardner, Randolph G., Panthee, Dilip R., Mutschler, Martha, Myers, James R., and Francis, David M.
Abstract:: The effects of selection on genome variation were investigated and visualized in tomato using a high-density single nucleotide polymorphism (SNP) array. 7,720 SNPs were genotyped on a collection of 426 tomato accessions (410 inbreds and 16 hybrids) and over 97% of the markers were polymorphic in the entire collection. Principal...

Recruitment, Growth and Mortality of an Antarctic Hexactinellid Sponge, Anoxycalyx joubini

Creator:: Dayton, Paul K., Kim, Stacy, Jarrell, Shannon C., Oliver, John S., Hammerstrom, Kamille, Fisher, Jennifer L., O'Connor, Kevin, Barber, Julie S., Robilliard, Gordon, Barry, James, Thurber, Andrew R., and Conlan, Kathy
Abstract:: Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...

High-Throughput Sequencing of Arabidopsis microRNAs : Evidence for Frequent Birth and Death of MIRNA Genes

Creator:: Fahlgren, Noah, Howell, Miya D., Kasschau, Kristin D., Sullivan, Christopher M., Cumbie, Jason S., Givan, Scott A., Law, Theresa F., Grant, Sarah R., Dangl, Jeffrey L., and Carrington, James C.
Abstract:: In plants, microRNAs (miRNAs) comprise one of two classes of small RNAs that function primarily as negative regulators at the posttranscriptional level. Several MIRNA genes in the plant kingdom are ancient, with conservation extending between angiosperms and the mosses, whereas many others are more recently evolved. Here, we use deep...

Historical Biogeography and Diversification of Truffles in the Tuberaceae and Their Newly Identified Southern Hemisphere Sister Lineage

Creator:: Bonito, Gregory, Smith, Matthew E., Nowak, Michael, Healy, Rosanne A., Guevara, Gonzalo, Cazares, Efren, Kinoshita, Akihiko, Nouhra, Eduardo R., Domınguez, Laura S., Tedersoo, Leho, Murat, Claude, Wang, Yun, Arroyo Moreno, Baldomero, Pfister, Donald H., Nara, Kazuhide, Zambonelli, Alessandra, Trappe, James M., and Vilgalys, Rytas
Abstract:: Truffles have evolved from epigeous (aboveground) ancestors in nearly every major lineage of fleshy fungi. Because accelerated rates of morphological evolution accompany the transition to the truffle form, closely related epigeous ancestors remain unknown for most truffle lineages. This is the case for the quintessential truffle genus Tuber, which includes...

O. C.
Abstract:: The seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and...
