The glutamine synthetases in soybean root nodules and free-living Rhizobium japonicum

Creator:: Guevara, Juan Garcia
Abstract:: Glutamine synthetase activity is present in both the cytosol and bacteroid fractions of soybean root nodules. Total activity measurements indicate that at least 90% of the activity in nodules is located in the cytosol. Results reported by McParland, et al. (29), showed that many properties of glutamine synthetase from nodule...

Photoinduction of kaurene synthetase, an enzyme of the gibberellin biosynthetic pathway, during de-etiolation of pea seedlings

Creator:: Gomez-Navarrete, Gladys
Abstract:: Previous investigations have shown that the enzymes catalyzing the biosynthesis of the gibberellin-type of hormones from mevalonic acid in plants are compartmentalized in plastids. Moreover, the activity of one of the key enzymes in the biosynthetic sequence, kaurene synthetase, exhibits markedly enhanced activity when a dark-grown pea seedling undergoes de-etiolation...

The Genome of Tolypocladium inflatum: Evolution, Organization, and Expression of the Cyclosporin Biosynthetic Gene Cluster

Creator:: Bushley, Kathryn E., Raja, Rajani, Jaiswal, Pankaj, Cumbie, Jason S., Nonogaki, Mariko, Boyd, Alexander E., Owensby, C. Alisha, Knaus, Brian J., Elser, Justin, Miller, Daniel, Di, Yanming, McPhail, Kerry L., and Spatafora, Joseph W.
Abstract:: The ascomycete fungus Tolypocladium inflatum, a pathogen of beetle larvae, is best known as the producer of the immunosuppressant drug cyclosporin. The draft genome of T. inflatum strain NRRL 8044 (ATCC 34921), the isolate from which cyclosporin was first isolated, is presented along with comparative analyses of the biosynthesis of...

Comparative Genome Structure, Secondary Metabolite, and Effector Coding Capacity across Cochliobolus Pathogens

Creator:: Condon, Bradford J., Leng, Yueqiang, Wu, Dongliang, Bushley, Kathryn E., Ohm, Robin A., Otillar, Robert, Martin, Joel, Schackwitz, Wendy, Grimwood, Jane, MohdZainudin, NurAinIzzati, Xue, Chunsheng, Wang, Rui, Manning, Viola A., Dhillon, Braham, Tu, Zheng Jin, Steffenson, Brian J., Salamov, Asaf, Sun, Hui, Lowry, Steve, LaButti, Kurt, Han, James, Copeland, Alex, Lindquist, Erika, Barry, Kerrie, Schmutz, Jeremy, Baker, Scott E., Ciuffetti, Lynda M., Grigoriev, Igor V., Zhong, Shaobin, and Turgeon, B. Gillian
Abstract:: The genomes of five Cochliobolus heterostrophus strains, two Cochliobolus sativus strains, three additional Cochliobolus species (Cochliobolus victoriae, Cochliobolus carbonum, Cochliobolus miyabeanus), and closely related Setosphaeria turcica were sequenced at the Joint Genome Institute (JGI). The datasets were used to identify SNPs between strains and species, unique genomic regions, core secondary...

Ferric-Pyoverdine Recognition by Fpv Outer Membrane Proteins of Pseudomonas protegens Pf-5

Creator:: Hartney, Sierra L., Mazurier, Sylvie, Girard, Maeva K., Mehnaz, Samina, Davis, Edward W. II, Gross, Harald, Lemanceau, Philippe, and Loper, Joyce E.
Abstract:: The soil bacterium Pseudomonas protegens Pf-5 (previously called P. fluorescens Pf-5) produces two siderophores, enantio-pyochelin and a compound in the large and diverse pyoverdine family. Using high-resolution mass spectroscopy, we determined the structure of the pyoverdine produced by Pf-5. In addition to producing its own siderophores, Pf-5 also utilizes ferric...

The Gac regulon of Pseudomonas fluorescens SBW25

Creator:: Cheng, Xu, de Bruijn, Irene, van der Voort, Menno, Loper, Joyce E., and Raaijmakers, Jos M.
Abstract:: Transcriptome analysis of Pseudomonas fluorescensSBW25 showed that 702 genes were differentially regulated in a gacS::Tn5 mutant, with 300 and 402 genes up- and downregulated respectively. Similar to the Gac regulon of other Pseudomonas species, genes involved in motility, biofilm formation, siderophore biosynthesis and oxidative stress were differentially regulated in the...

Secondary Metabolism in Tolypocladium : Characterization, Ecology, Evolution and Regulation

Creator:: Blount, Rheannon Rua
Abstract:: An increased understanding of secondary metabolism in fungi is important for both biological and societal reasons. The ascomycete genus, Tolypocladium, is an ideal system to explore secondary metabolism characterization, ecology, evolution and regulation. The genus produces and has the genomic potential to produce a wide array of metabolites. Paired with...

TonB-dependent outer-membrane proteins of Pseudomonas fluorescens : diverse and redundant roles in iron acquisition

Creator:: Hartney, Sierra L.
Abstract:: Pseudomonas is a diverse genus of Gram-negative bacteria that includes pathogens of plants, insects, and humans as well as environmental strains with no known pathogenicity. Pseudomonas fluorescens itself encompasses a heterologous group of bacteria that are prevalent in soil and on foliar and root surfaces of plants. Some strains of...
