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...

Physiology of senescence of the shoot apex in Pisum sativum L.

Creator:: Ecklund, Paul Richard, 1941-
Abstract:: Shoot apex senescence is defined as the collective progressive and deteriorative processes which ultimately terminate the functional life of the shoot apex. Senescence of shoot apices of Pisum sativum L. 'Alaska' as measured by cessation of stem elongation was delayed by removal of flowers and by treatment with gibberellin A₃...

Identification and distribution of the mating-type locus and development of cleistothecia of Podosphaera macularis

Creator:: Wolfenbarger, Sierra N.
Abstract:: Podosphaera macularis, causal agent of hop powdery mildew, is known to produce cleistothecia (syn. chasmothecia) in eastern North America and Europe, but ascocarps are not reported from the Pacific Northwestern region of North America. Reasons for the apparent absence of cleistothecia in the Pacific Northwest are unknown. We established that...

Hybridization between Castilleja levisecta and C. hispida : Implications for Pacific Northwest Prairie Management

Creator:: Sandlin, Isaac J., III
Abstract:: Conservation conflicts may develop on restoration sites with multiple species recovery objectives. For example, on Pacific Northwest prairies, the co-planting of the diploid cytotype of the common native wildflower Castilleja hispida with the endangered wildflower C. levisecta has resulted in putative Castilleja hybrids on restoration sites, prompting fears that genetic...

Distinct Argonaute-mediated 22G-RNA pathways direct genome surveillance in the C. elegans germline

Creator:: Gu, Weifeng, Shirayama, Masaki, Conte Jr., Darryl, Vasale, Jessica, Batista, Pedro J., Claycomb, Julie M., Moresco, James J., Youngman, Elaine, Keys, Jennifer, Stoltz, Matthew J., Chen, Chun-Cheih G., Chaves, Daniel A., Duan, Shenghua E., Kasschau, Krisitin D., Fahlgren, Noah, Yates III, John R., Mitani, Shohei, Carrington, James C., and Mello, Craig C.
Abstract:: Endogenous small RNAs (endo-siRNAs) interact with Argonaute (AGO) proteins to mediate sequence-specific regulation of diverse biological processes. Here, we combine deep-sequencing and genetic approaches to explore the biogenesis and function of endo-siRNAs in C. elegans. We describe conditional alleles of the dicer-related helicase, drh-3, that abrogate both RNA interference and...

Inferring Patterns and Processes of Emergence in Clonal Phytophthora Epidemics using Population Genomic Approaches

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

Characterization of the transition to the progamic phase in Zea mays pollen

Creator:: Smyth, Johanna C.
Abstract:: The transition of mature pollen to the progamic phase represents an important step in the regulation of plant sexual reproduction. The progamic phase encompasses the initiation of pollen tube germination, growth of the pollen tube through the stigma (the silk in maize) and concludes with fertilization of the female gametophyte....
