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...

Interactive effects of stripe rust and plant competition in heterogeneous wheat populations

Creator:: Finckh, Maria Renate
Abstract:: Disease has been implied as an important selective force acting in plant populations. This study was conducted to determine the effects of stripe rust (Puccinia striiformis) on the population dynamics of wheat (Triticum aestivum) cultivar mixtures. Five wheat cultivars were grown in pure stands and all possible mixtures at three...

Morphogentic studies of intraspecific hybrids of Microseris laciniata (Hook.) Sch.-Bip.

Creator:: Pires, Maria Joaquina Pinheiro
Abstract:: Microseris laciniata is a perennial, self-incompatible species classified in subgenus Scorzonella. It is morphologically the least specialized species in the genus, in contrast to the members of subgenus Microseris, which are morphologically advanced, self-compatible annuals. First-generation hybrids were available from crosses involving eight populations of two subspecies of Microseris laciniata...

Interactions between pea seed-borne mosaic virus pathotype 1 and Pisum sativum resistance gene sbm-1

Creator:: Keller, Karen E.
Abstract:: Pea seed-borne mosaic potyvirus pathotype 1 (PSbMV-P1) has the ability to infect most genotypes of Pisum sativum. The exception are those genotypes that are homozygous recessive for the sbm-1 gene. The life cycle of PSbMV pathotype 4 (PSbMV-P4) is unaffected by the sbm-1/sbm-1 genotype. Infectious clones of Pl-P4 recombinants were...

Serological and molecular approaches for distinguishing bean common mosaic and bean common mosaic necrosis potyviruses and their respective pathogroups

Creator:: Xu, Ling, 1963-
Abstract:: Polyclonal antisera were raised against isolates of bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV) using conventional serological methods. Infected tissues containing, respectively, 22 recognized BCMV and BCMNV isolates were tested against the two antisera by antigen-coated plate (ACP) ELISA and double antibody sandwich (DAS) ELISA....

Roles and Programming of Arabidopsis ARGONAUTE Proteins during Turnip Mosaic Virus Infection

Creator:: Garcia-Ruiz, Hernan, Carbonell, Alberto, Hoyer, J. Steen, Fahlgren, Noah, Gilbert, Kerrigan B., Takeda, Atsushi, Giampetruzzi, Annalisa, Garcia Ruiz, Mayra T., McGinn, Michaela G., Lowery, Nicholas, Martinez Baladejo, Maria T., and Carrington, James C.
Abstract:: In eukaryotes, ARGONAUTE proteins (AGOs) associate with microRNAs (miRNAs), short interfering RNAs (siRNAs), and other classes of small RNAs to regulate target RNA or target loci. Viral infection in plants induces a potent and highly specific antiviral RNA silencing response characterized by the formation of virus-derived siRNAs. Arabidopsis thaliana has...

Ontologies as Integrative Tools for Plant Science

Creator:: Walls, Ramona L., Athreya, Balaji, Cooper, Laurel, Elser, Justin, Gandolfo, Maria A., Jaiswal, Pankaj, Mungall, Christopher J., Preece, Justin, Rensing, Stefan, Smith, Barry, and Stevenson, Dennis W.
Abstract:: Premise of the study: Bio-ontologies are essential tools for accessing and analyzing the rapidly growing pool of plant genomic and phenomic data. Ontologies provide structured vocabularies to support consistent aggregation of data and a semantic framework for automated analyses and reasoning. They are a key component of the semantic web....

Host-Specific Involvement of the HC Protein in the Long-Distance Movement of Potyviruses

Creator:: Sáenz, Pilar, Salvador, Beatriz, Simón-Mateo, Carmen, Kasschau, Kristin D., Carrington, James C., and García, Juan Antonio
Abstract:: Plum pox virus (PPV) is a member of the Potyvirus genus that, in nature, infects trees of the Prunus genus. Although PPV infects systemically several species of the Nicotiana genus, such as N. clevelandii and N. benthamiana, and replicates in the inoculated leaves of N. tabacum, it is unable to...

Functional Analysis of Three Arabidopsis ARGONAUTES Using Slicer-Defective Mutants

Creator:: Carbonell, Alberto, Fahlgren, Noah, Garcia-Ruiz, Hernan, Gilbert, Kerrigan B., Montgomery, Taiowa A., Nguyen, Tammy, Cuperus, Josh T., and Carrington, James C.
Abstract:: In RNA-directed silencing pathways, ternary complexes result from small RNA-guided ARGONAUTE (AGO) associating with target transcripts. Target transcripts are often silenced through direct cleavage (slicing), destabilization through slicer-independent turnover mechanisms, and translational repression. Here, wild-type and active-site defective forms of several Arabidopsis thaliana AGO proteins involved in posttranscriptional silencing were...

The Plant Ontology as a Tool for Comparative Plant Anatomy and Genomic Analyses

Abstract:: The Plant Ontology (PO;http://www.plantontology.org/" is a publicly available, collaborative effort to develop and maintain a controlled, structured vocabulary ('ontology') of terms to describe plant anatomy, morphology and the stages of plant development. The goals of the PO are to link (annotate) gene expression and phenotype data to plant structures and...
