Environmental factors influencing the rate of spread of Phellinus weirii (Murr.) Gilbertson in young-growth Douglas-fir

Creator:: Angwin, Peter A.
Abstract:: Studies to identify the environmental factors that influence the rate of ectotrophic mycelial growth of Phellinus weirii (Murr.) Gilbertson along Douglas-fir roots were undertaken both in the laboratory and in the field. The effects of soil pH, nitrogen, moisture, temperature, microorganisms and bulk density were investigated. In the lab, the...

Genetics of sexuality and population genetics of Phellinus weirii

Creator:: Angwin, Peter A.
Abstract:: Phellinus weirii (Murr.) Gilbertson, cause of laminated root and butt rot, is a heterothallic basidiomycete lacking clamp connections. Two biological species groups of the fungus have been hypothesized, the Douglas-fir and cedar-types, on the basis of physiological, morphological and epidemiological differences. Single-spore and vegetative isolates differ in cultural morphology, nuclear...

Patterns in the occupancy and abundance of the globally rare lichen Erioderma pedicellatum in Denali National Park and Preserve, Alaska

Creator:: Stehn, Sarah E., Nelson, Peter R., Roland, Carl A., and Jones, Jennifer R.
Abstract:: We investigated habitat attributes related to the occupancy of the globally rare and endangered epiphytic lichen, Erioderma pedicellatum, in a newly discovered (2009) population center in Denali National Park and Preserve (DNPP), Alaska. We measured forest, tree and epiphytic lichen community characteristics on eighty-five systematically selected plots in four study...

Thauera butanivorans sp. nov., a C₂–C₉ alkane-oxidizing bacterium previously referred to as ‘Pseudomonas butanovora’

Creator:: Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: The placement of ‘Pseudomonas butanovora’ in the genus Thauera was proposed previously, based on 16S rRNA gene sequence analysis, upon further studies of taxonomical characteristics. In this study, physiological characteristics and DNA–DNA reassociation data are presented and the transfer of ‘P. butanovora’ to the genus Thauera is proposed. The original...

Kinetic characterization of the soluble butane monooxygenase from Thauera butanivorans, formerly ‘Pseudomonas butanovora’

Creator:: Cooley, Richard B., Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: Soluble butane monooxygenase (sBMO), a three-component di-iron monooxygenase complex expressed by the C2–C9 alkane-utilizing bacterium Thauera butanivorans, was kinetically characterized by measuring substrate specificities for C1–C5 alkanes and product inhibition profiles. sBMO has high sequence homology with soluble methane monooxygenase (sMMO) and shares a similar substrate range, including gaseous and...

The ERI-6/7 Helicase Acts at the First Stage of an siRNA Amplification Pathway That Targets Recent Gene Duplications

Creator:: Fischer, Sylvia E. J., Montgomery, Taiowa A., Zhang, Chi, Fahlgren, Noah, Breen, Peter C., Hwang, Alexia, Sullivan, Christopher M., Carrington, James C., and Ruvkun, Gary
Abstract:: Endogenous small interfering RNAs (siRNAs) are a class of naturally occuring regulatory RNAs found in fungi, plants, and animals. Some endogenous siRNAs are required to silence transposons or function in chromosome segregation; however, the specific roles of most endogenous siRNAs are unclear. The helicase gene eri-6/7 was identified in the...

Whole-Plant Growth Stage Ontology for Angiosperms and Its Application in Plant Biology

Creator:: Pujar, Anuradha, Jaiswal, Pankaj, Kellogg, Elizabeth A., Ilic, Katica, Vincent, Leszek, Avraham, Shulamit, Stevens, Peter, Zapata, Felipe, Reiser, Leonore, Rhee, Seung Y., Sachs, Martin M., Schaeffer, Mary, Stein, Lincoln, Ware, Doreen, and McCouch, Susan
Abstract:: Plant growth stages are identified as distinct morphological landmarks in a continuous developmental process. The terms describing these developmental stages record the morphological appearance of the plant at a specific point in its life cycle. The widely differing morphology of plant species consequently gave rise to heterogeneous vocabularies describing growth...

Plant Ontology (PO): a controlled vocabulary of plant structures and growth stages

Abstract:: The Plant Ontology Consortium (POC) (www.plantontology.org) is a collaborative effort among several plant databases and experts in plant systematics, botany and genomics. A primary goal of the POC is to develop simple yet robust and extensible controlled vocabularies that accurately reflect the biology of plant structures and developmental stages. These...

Abstract:: The Plant Ontology Consortium (POC, http://www.plantontology.org) is a collaborative effort among model plant genome databases and plant researchers that aims to create, maintain and facilitate the use of a controlled vocabulary (ontology) for plants. The ontology allows users to ascribe attributes of plant structure (anatomy and morphology) and developmental stages...

The Plant Structure Ontology, a Unified Vocabulary of Anatomy and Morphology of a Flowering Plant

Abstract:: Formal description of plant phenotypes and standardized annotation of gene expression and protein localization data require uniform terminology that accurately describes plant anatomy and morphology. This facilitates cross species comparative studies and quantitative comparison of phenotypes and expression patterns. A major drawback is variable terminology that is used to describe...
