Gene expression analysis in wild-type and OsGRX8 overexpression line in response to various treatments
  • organism-icon Arabidopsis thaliana
  • sample-icon 16 Downloadable Samples
  • Technology Badge Icon Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)

Description

Glutaredoxins (GRXs) are the ubiquitous oxidoreductase enzymes, which play important role in defense against various stresses. To analyze the function of a CC-type rice GRX gene, OsGRX8, we overexpressed it into Arabidopsis constitutively. The physiological analyses revealed that overexpression of GRX gene enhanced abiotic stress tolerance in transgenic plants as compared to wild-type.

Publication Title

Modified expression of an auxin-responsive rice CC-type glutaredoxin gene affects multiple abiotic stress responses.

Gene expression analysis in wild-type and OsHOX24 rice overexpression line under control and drought stress conditions
  • organism-icon Oryza sativa
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix Rice (US) Gene 1.0 ST Array (rusgene10st)

Description

Several homeobox genes belonging to HD-ZIP I subfamily are highly induced by drought stress at various developmental stages in rice. To analyze the role of a candidate HD-ZIP I subfamily member, OsHOX24, we constitutively overexpressed it in rice. The physiological analyses revealed that overexpression of OsHOX24 gene reduced drought stress tolerance in transgenic plants as compared to wild-type.

Analyzing the metabolic stress response of recombinant Escherichia coli cultures expressing human interferon beta in high cell density fed batch cultures using time course transcriptomic data
  • organism-icon Escherichia coli
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix E. coli Genome 2.0 Array (ecoli2)

Description

Over expression of recombinant proteins is known to cause a metabolic burden to the host cells which leads to down regulation of both growth rates and protein expression. Most studies in this regard have been conducted in low density shake flask cultures which does not capture the essential features of an industrial scale bioprocess. In the present work we studied the transcriptomic profiling at different specific growth rates while expressing the recombinant human interferon beta in fed batch cultures with complex media. These conditions mimicked the industrial fermentations for recombinant proteins.

Publication Title

Uncoupling growth and product formation kinetics to design improved strains for recombinant protein production in escherichia coli
  • organism-icon Escherichia coli
  • sample-icon 11 Downloadable Samples
  • Technology Badge Icon Affymetrix E. coli Genome 2.0 Array (ecoli2)

Description

The ability to control the synthesis of products in the absence of cell division remains an attractive alternative for the optimization of microbial processes. If this could be achieved, it would dramatically expand the productivity of many microbial processes by increasing product synthesis in the absence of an increase in cell mass. In the present work we have looked at the factors involved in the design of a host where the fluxes would be channeled towards product formation rather than biomass synthesis. To identify the genes responsible for diverting the metabolic flux specifically towards product formation we have used for this study is quiescent-cell (Q-cell) expression system, in which a plasmid-encoded protein is expressed in nongrowing but metabolically active cells. These cells channel the metabolic flux towards recombinant protein production and therefore the specific product yield per unit biomass is significantly higher. Indole which is previously known to be a signalling molecule is here used as an inducer of Quiescence. E.coli L-Asparaginase is used as a model protein in this work.

Description

Homeobox transcription factors are known to regulate plant growth and development. Recently, they have also been implicated in abiotic stress responses. To analyze the role of HD-ZIP I subfamily member, OsHOX24, we constitutively overexpressed it in Arabidopsis. The physiological analyses revealed that overexpression of OsHOX24 gene severely reduced abiotic stress tolerance in transgenic plants as compared to wild-type.

Description

Indica rice seedlings of IR64 variety were grown hydroponically for 7-days in a culture room with a daily photoperiodic cycle of 14h light and 10h dark. Seedlings were incubated in 0.1% dimethyl sulfoxide (control) or 50 micromolar solutions of indole-3-acetic acid (IAA treatment) and benzyl aminopurine (BAP treatment) for 1h and 3h. Equal amounts of 1h and 3h samoles were pooled for each treatment before RNA isolation. The 5 micrograms of each total RNA sample was processed for microarray analysis according to Affymetrix protocol.
