We recently demonstrated that cell elongation in plants is regulated by a triantagonistic bHLH system, in which three bHLH proteins, Activator of Cell Elongation 1 (ACE1), Arabidopsis ILI1 binding BHLH 1 (AtIBH1) and Paclobutrazol Resistance 1 (PRE1), competitively regulate the expression of genes for cell elongation. Here we show that ATBS1 Interacting Factor 2 (AIF2), AIF3 and AIF4 interact w...

Fusarium commune sp. nov. was isolated from soil and Pisum sativum in Denmark and several widespread locations within the northern hemisphere from diverse substrates including white pine, Douglas fir, carnation, corn, carrot, barley and soil. Fusarium commune is characterized by and distinguished from its putative sister taxon, the F. oxysporum complex, in having long, slender monophialides and...

The currently available morphological and molecular diagnostic techniques for Fusarium redolens and the three phylogenetic clades of Fusarium oxysporum are problematic. Aligned translation elongation factor 1 alpha (TEF-1 alpha) gene sequences from these species and their close relatives were used to design F. redolens-specific primers, and to identify restriction sites that discriminate among ...

A shipment of Fults alkaligrass seed (Puccinellia distans) grown in Washington state containing bunted florets was intercepted by quarantine officials at China's Tianjin Entry-Exit Quarantine and Inspection Bureau. The bunted florets were filled with irregularly shaped, reticulately ornamented teliospores that germinated in a manner characteristic of systemically infecting Tilletia spp. on gras...

The stalling of RNA polymerase II (RNAPII) at the promoters of many genes, including developmental regulators, stress-responsive genes, and HIVLTR, suggests transcription elongation as a critical regulatory step in addition to initiation. Spt5, the large subunit of the DRB sensitivity-inducing factor (DSIF), represses or activates RNAPII elongation in vitro. How RNAPII elongation is repressed i...

The interaction of translational elongation factor EF-G with the ribosome in the posttranslocational state has been mapped by directed hydroxyl radical probing. Localized hydroxyl radicals were generated from Fe(II) tethered to 18 different sites on the surface of EF-G bound to the ribosome. Cleavages in ribosomal RNA were mapped, providing proximity relationships between specific sites of EF-G...

Fusarium is a large and diverse genus of fungi of great agricultural and economic importance, containing many plant pathogens and mycotoxin producers. To date, high-throughput sequencing of Fusarium communities has been limited by the lack of genus-specific primers targeting regions with high discriminatory power at the species level. In the present study, we evaluated two Fusarium-specific pri...
