Complementation of tobacco etch potyvirus mutants by active RNA polymerase expressed in transgenic cells

Creator:: Li, Xiao Hua and Carrington, James C.
Abstract:: A genetic complementation system was developed in which tobacco etch virus (TEV) polymerase (NIb)- expressing transgenic plants or protoplasts were inoculated with NIb-defective TEV mutants. A β-glucuronidase (GUS) reporter gene integrated into the genomes of parental and four mutant viruses was used to assay RNA amplification. Two mutants (termed VNN...

Small RNAs serve as a genetic buffer against genomic shock in Arabidopsis interspecific hybrids and allopolyploids

Creator:: Ha, Misook, Lu, Jie, Ramachandran, Vanitharani, Kasschau, Krisitin D., Chapman, Elisabeth J., Carrington, James C., Chen, Xuemei, Wang, Xue-Jei, and Chen, Z. Jeffrey
Abstract:: Small RNAs, including microRNAs (miRNAs), small interfering RNAs (siRNAs), and trans-acting siRNAs (tasiRNAs), control gene expression and epigenetic regulation. Although the roles of miRNAs and siRNAs have been extensively studied, their expression diversity and evolution in closely related species and interspecific hybrids are poorly understood. Here, we show comprehensive analyses...

Identification of MIR390a precursor processing defective mutants in Arabidopsis by direct genome sequencing

Creator:: Cuperus, Josh T., Montgomery, Taiowa A., Fahlgren, Noah, Burke, Russell T., Townsend, Tiffany, Sullivan, Christopher M., and Carrington, James C.
Abstract:: Transacting siRNA (tasiRNA) biogenesis in Arabidopsis is initiated by microRNA (miRNA) –guided cleavage of primary transcripts. In the case of TAS3 tasiRNA formation, ARGONAUTE7 (AGO7)– miR390 complexes interact with primary transcripts at two sites, resulting in recruitment of RNA-DEPENDENT RNA POLYMERASE6 for dsRNA biosynthesis. An extensive screen for Arabidopsis mutants...

Danebo Wetland Prairie Project Environmental Education Curriculum

Creator:: Windham, George, Wagner, Jan, Ruzicka, Angela, Clark, Deborah Louise, 1950-, Wilson, Mark V., and Lederman, Norman
Abstract:: One goal of this environmental education curriculum is that students will gain an appreciation of Willamette Valley wetland prairies, a threatened ecosystem, and will gain an understanding of the importance of protecting these wetlands. A second goal is that students will see first-hand the processes involved in conducting scientific field...

Final report: Predicting field establishment rates from standardized plant traits - Year two of: Restoring prairies: A synthesis of studies on vegetation and invasive species in support of effective management

Creator:: Wilson, Mark V., Clark, Deborah Louise, 1950-, and Roberts, Rachel E.
Abstract:: Willamette Valley wetland prairies are some of the most endangered ecosystems in the United States, and provide habitat for many federally listed species (Wilson et al. 1993, Noss et al. 1995, USFWS 2000, Schultz et al. 2003). A rigorous program of ecosystem restoration can protect and enhance wetland plants, animals,...

Controlling woody vegetation in wetland prairies, 1994-2001

Creator:: Clark, Deborah Louise, 1950-
Abstract:: Wetland prairies of the Willamette Valley, among the rarest of Oregon’s ecosystems, are threatened by invasion of woody species and non-native pest species. Because fire has been important in maintaining Willamette Valley prairies for at least 1000 years, prescribed burning is a top choice of managers for preventing encroachment of...

Increasing the abundance of rare native wetland prairie species

Creator:: Clark, Deborah Louise, 1950-, Wilson, Mark V., and Goodridge, Jennifer
Abstract:: Native prairies of the Willamette Valley are considered among the rarest of Oregon’s ecosystems and are in critical need of conservation. Management strategies for increasing the abundance of native species are urgently needed, particularly those strategies that promote the regeneration of native species from seed. Fire may be an important...

Progress report [I]: Restoring prairies: A synthesis of studies on vegetation and invasive species in support of effective management (Year two)

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
Abstract:: Willamette Valley wetland and upland prairies are some of the most endangered ecosystems in the United States, and provide habitat for many federally listed species. These are dynamic systems, subject to ecological succession and invasion by aggressive non-native species, and require active management to maintain management goals. This is true...
