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...
The semi-arid sagebrush steppe ecosystem is one of the largest biomes in
North America. The steppe provides critical habitat and forage for wildlife and is
economically important to recreation and livestock industries. However, the ecosystem
is threatened primarily due to several negative effects associated with expansion of the
exotic annual...
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...
This dataset contains a draft assembly of the common milkweed (Asclepias syriaca) nuclear genome, linkage group information, and gene family counts for Asclepias and related species. The genome assembly is accompanied by annotation of gene models, repeat models, transfer RNAs, and open reading frames, and mapping information of Asclepias transcripts,...
This dataset is available as supplement for a research article submitted in 2018 and accepted in 2019. Genomic resources for the Neotropical tree genus Cedrela (Meliaceae) and its relatives. By Kristen N. Finch, B.A.; F. Andrew Jones, Ph.D.; Richard Cronn, Ph.D.
Tree species in the genus Cedrela are threatened by...
Most studies of plant disease epidemiology have focused on epidemics in host
populations composed of a single genotype. But crop plant diversity can be a useful
means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...
This study quantified the frequency of simple versus
complex races of Puccinia striiformis Westend. in mixtures
of wheat cultivars possessing different race-specific
resistance genes. A simple race of a pathogen can infect
only one component, and a complex race of the pathogen can
infect two or more components of an...
Two experiments involving interactions between wheat
(Triticum aesitivium L.) cultivars and rust pathogens were
investigated. One experiment evaluated the aggressiveness
(measured by infection efficiency and latent period) of
populations of Puccinia recondita Rob. when inoculated on
the cultivar they were isolated from, their "own" cultivar,
and when inoculated onto other...
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...
