A LexA-related protein regulates redox-sensitive expression of the cyanobacterial RNA helicase, crhR
Download2006
Patterson-Fortin, L.M., Owttrim, G.W., Colvin, K.R.
Expression of the cyanobacterial DEAD-box RNA helicase, crhR, is regulated in response to conditions, which elicit reduction of the photosynthetic electron transport chain. A combination of electrophoretic mobility shift assay (EMSA), DNA affinity chromatography and mass spectrometry identified...

An alternative physiological role for the EmhABC efflux pump in Pseudomonas fluorescens cLP6a
Download2011
Background Efflux pumps belonging to the resistance-nodulation-division (RND) superfamily in bacteria are involved in antibiotic resistance and solvent tolerance but have an unknown physiological role. EmhABC, a RND-type efflux pump in Pseudomonas fluorescens strain cLP6a, extrudes hydrophobic...

Li, R., Wang, J., Wong, G.K.S., Zheng, H., Xu, S., Clark, T., Zheng, X., Vang, S.
Background Gene conversion causes a non-reciprocal transfer of genetic information between similar sequences. Gene conversion can both homogenize genes and recruit point mutations thereby shaping the evolution of multigene families. In the rice genome, the large number of duplicated genes...

Generation, annotation, analysis and database integration of 16,500 white spruce EST clusters
Download2005
Johnson, J.E., Pavy, N., Cooke, J., Parsons, L., Paule, C., Morency, M.J., Crow, J.A.
Background: The sequencing and analysis of ESTs is for now the only practical approach for largescale gene discovery and annotation in conifers because their very large genomes are unlikely to be sequenced in the near future. Our objective was to produce extensive collections of ESTs and cDNA...

Identification and expression analysis of WRKY transcription factor genes in canola (Brassica napus L.) in response to fungal pathogens and hormone treatments
Download2009
Kav, N.N., Rahman, M.H., Yang, B., Deyholos, M.K., Jiang, Y.
Background: Members of plant WRKY transcription factor families are widely implicated in defense responses and various other physiological processes. For canola (Brassica napus L.), no WRKY genes have been described in detail. Because of the economic importance of this crop, and its evolutionary...

RNA helicases function as molecular motors that rearrange RNA secondary structure, potentially performing roles in any cellular process involving RNA metabolism. Although RNA helicase association with a range of cellular functions is well documented, their importance in response to abiotic stress...
