2023年南京农业大学和江苏省农业科学院植物保护研究所研究团队在期刊Journal of Integrative Agriculture(IF:4.8)发表了题为“Sigma factor 70 RpoD contributes to virulence by regulating cell motility, oxidative stress tolerance, and manipulating the expression ofhrpGandhrpXinXanthomonas oryzae pv. Oryzae-”的研...
We have determined the nucleotide sequences of rpoD genes encoding RNA polymerase sigma 70 factor of type strains of the genus Vibrio and of stock strains of Vibrio parahaemolyticus (strains containing and those not containing toxin gene); elucidated the phylogenetic relation, and identified ...
σ70 (RpoD) - the "housekeeping" sigma factor, transcribes most genes in growing cells. Makes the proteins necessary to keep the cell alive. σ54 (RpoN) - the nitrogen-limitation sigma factor σ38 (RpoS) - the starvation/stationary phase sigma factor σ32 (RpoH) - the heat shock...
Sigma factorsin E. coli: σ70(RpoD) –σA– the "housekeeping"sigma factoror also called as primarysigma factor, transcribes most genes in growing cells. WikiMatrix SigB, an alternativesigma factor, up-regulates Vir genes in the intestines, whereas PrfA up-regulates gene expression when the...
In addition, we searched putative RpoD-dependent genes based on these promoter elements on the whole genome sequence of phytoplasmas using in silico tools. The phytoplasmal RpoD seems to mediate the transcription of not only many housekeeping genes as the principal sigma factor, but also the ...
coli strain library with all non-essential genes systematically deleted, we unexpectedly discovered upon whole-genome sequencing that the improved phenotype was not conferred by the deleted genes but by various subtle alterations in the "housekeeping" sigma 70 factor (RpoD). When analyzing effects of...
(for example RegSR/RegAB, FixLJ, FixK, NtrBC, NifA [1-3]), some of them (NtrC and NifA) belong to Fis-family of enhancer-binding transcription factors activating RpoN (σ54)-dependent promoters, however sigma-factor RpoD (σ70) remains crucial for the expression of majority of genes...
σ70sigma factor (RpoD) and RpoS tend to be similar (Hengge-Aronis, 2002b). One factor that is important in determining RpoS promoter specificity is the sequence of the extended -10 region. In agreement with this, Eggers et al. confirmed that the -12 to -16 region provided RpoS ...
RNA polymerase sigma 70 (also known as RNA pol sigma70 and rpoD) is a part of a family of sigma factor subunits that are required for specificpromoter recognition and initiation. RNA pol sigma 70 is the major housekeeping sigma factorresponsible for RNA polymerase recognition out of the ...
strain PCC 7942 RpoD1 (a principal sigma factor of the sigma 70 type) indicated that M. aeruginosa K-81 RpoD1 (sigma A1) is the principal sigma factor, which is a major component of the sigma subunit on exponential cell growth. 展开 ...
