The ability to modify RNA secondary structure is crucial for numerous cellular processes. We have characterized two RNA helicase genes, crhB and crhC, which are differentially expressed in the cyanobacterium Anabaena sp. strain PCC 7120. crhC transcription is limited specifically to cold shock...

Background: Bast fibres from the phloem tissues of flax are scientifically interesting and economically useful due in part to a dynamic system of secondary cell wall deposition. To better understand the molecular mechanisms underlying the process of cell wall development in flax, we extracted...

Crystallization and preliminary diffraction studies of TraF, a component of the Escherichia coli type IV secretory system
Download2004
Manchak, J., Hayakawa, K., Audette, G.F., Holland, S.J., Frost, L.S., Hazes, B.
TraF, a component of the Escherichia coli type IV secretory system, has been crystallized and preliminary X-ray diffraction data have been collected. TraF is a 26 kDa protein encoded by the E. coli F plasmid and is required for conjugative plasmid transfer and the formation of sex pili. The...

Differential exudation of polypeptides by roots of aluminum-resistant and aluminum-sensitive cultivars of Triticum aestivum L. in response to aluminum stress
Download1994
Basu, A., Taylor, G. J., Basu, U.
Cultivars of Triticum aestivum differing in resistance to Al were grown under aseptic conditions in the presence and absence of Al and polypeptides present in root exudates were collected, concentrated, and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Upon exposure to...

Drosophila ATM and ATR have distinct activities in the regulation of meiotic DNA damage and repair

Tiong, S., McKim, K.S., Campbell, S.D., White-Brown, S.K., Paul, A., Pedersen, M., Joyce, E.F.
Ataxia telangiectasia–mutated (ATM) and ataxia telangiectasia–related (ATR) kinases are conserved regulators of cellular responses to double strand breaks (DSBs). During meiosis, however, the functions of these kinases in DSB repair and the deoxyribonucleic acid (DNA) damage checkpoint are...

Endogenous melanocortin antagonist in fish: Structure, brain mapping and regulation by fasting of the goldfish agouti-related protein gene
Download2003
Cerdá-Reverter, J.M., Peter, R.E.
Agouti-related protein (AGRP) is a naturally occurring antagonist of melanocortin. In mammals, central AGRP expression is restricted to the arcuate nucleus in which it plays a key role in the control of energy balance by antagonizing melanocortin effects at melanocortin 4 receptors. In goldfish,...

Tenniswood, M., Bennett, S., Wong, P., Morrissey, C., Nitsche, E., Guenette, R.S.
After hormonal ablation, 90% of the secretory epithelial cells of the prostate undergo apoptosis, and the remaining cells are reorganized as the tissue is remodeled. Using differential display RT-PCR of total RNA extracted from the rat ventral prostate before and 4 days after castration, we have...

Gawky Is a Component of Cytoplasmic mRNA Processing Bodies Required for Early Drosophila Development
Download2006
Hobman, T. C., Locker, J., Schneider, M. D., Pare, J. M., Haskins, J., Simmonds, A. J., Chaker, S., Najand, N
In mammalian cells, the GW182 protein localizes to cytoplasmic bodies implicated in the regulation of messenger RNA ( mRNA) stability, translation, and the RNA interference pathway. Many of these functions have also been assigned to analogous yeast cytoplasmic mRNA processing bodies. We have...

Transcript regulation in response to high salinity was investigated for salt-tolerant rice (var Pokkali) with microarrays including 1728 cDNAs from libraries of salt-stressed roots. NaCl at 150 mM reduced photosynthesis to one tenth of the prestress value within minutes. Hybridizations of RNA to...

Generation of a restriction minus enteropathogenic Escherichia coli E2348/69 strain that is efficiently transformed with large, low copy plasmids

Raivio, T.L., Price, N.L., Ward, J.D., Hobson, N.
Background Many microbes possess restriction-modification systems that protect them from parasitic DNA molecules. Unfortunately, the presence of a restriction-modification system in a given microbe also hampers genetic analysis. Although plasmids can be successfully conjugated into the...
