STOP2 activated transcription in the stop1-mutant: STOP2-complemented lines (stop1-mutant with transformed STOP2) vs. stop1-mutant of Arabidopsis

ABSTRACT: Transcriptional profiling of genes recoverd by STOP2-complementation in the stop1-mutant (STOP2 expression is repressed in the stop1-mutant). The roots were exposed to Al and low pH stressed conditions, then genes recovered expression were analyzed. Goal is identifying the genes can be actevated the expression by STOP2. Two-condition experiment, STOP2-complemented lines (stop1-mutant backgoround) v.s. stop1-mutant. Biological replicates: 3 of low pH treatments replicates, 3 Al treatment replicates.

The zinc-finger protein STOP1 (sensitive to proton rhizotoxicity 1) regulates transcription of multiple genes critical for tolerance to aluminum (Al) and low pH in Arabidopsis. We evaluated the contributions of genes that are suppressed in the stop1 mutant to Al- and low pH-tolerance using T-DNA-inserted disruptants, and transgenic stop1 mutants expressing each of the suppressed genes. STOP2, a STOP1 homolog, partially recovered Al- and low pH-tolerance by recovering the expression of genes regu ...[more]

Comparative expression analysis between PfmR (TTHB023) deletion mutant and wild-type of Thermus thermophilus HB8

Project description:We observed the expression profile of the total mRNA of PfmR (TTHB023) deletion mutant of Thermus thermophilus HB8 strain grown in a rich (TT) medium at 70M-BM-0C compared with that of wild type. Seven wild-type and three mutant T. thermophilus HB8 strains were each pre-cultured at 70M-BM-0C for 16 h in 4 ml of TT medium containing 0.8% polypeptone, 0.4% yeast extract, 0.2% NaCl, 0.4 mM CaCl2, and 0.4 mM MgCl2, which was adjusted to pH 7.2 with NaOH. The cells were inoculated into 1 liter of the same medium and then cultivated at 70M-BM-0C. Cells were collected after 360 min, and then crude RNA was extracted. In order to compare mRNA expression in the PfmR deletion mutant with that of wild type, the expression of each mRNA was analyzed on a GeneChip.

Transcriptomic analysis of an iron-resistant Saccharomyces cerevisiae mutant obtained by evolutionary engineering

Project description:Iron-resistant Saccharomyces cerevisiae mutant was obtained by evolutionary engineering selection strategy. The mutant obtained M-bM-^@M-^\M8FEM-bM-^@M-^] is much more resistant to iron stress than the reference strain which was used to select this mutant. Mutant can resist up to 35mM Iron* stress whereas the reference strain cannot. Whole-genome microarray analysis might be promising to identify the iron resistance mechanisms and stress response upon high levels of iron in the yeast cells. Iron-resistant mutant is also cross resistant to Cobalt, Chromium and Nickel but sensitive to Zinc. * refers to [NH4]2[Fe][SO4]2 and FeCl2. The reference Saccharomyces cerevisiae strain and the iron-resistant mutant were grown in minimal medium to an Optical Density (OD600) of 1.00 which correspond to the logarithmic growth phase of the yeast cells. Cultures were harvested and whole RNA isolation was carried out. The experiment was repeated three times.

Differential expression analysis between litR (TTHB100) deletion mutant and wild-type of Thermus thermophilus HB8 under the dark condition.

Project description:We observed the expression profile of the total mRNA of litR (TTHB100) deletion mutant of T. thermophilus HB8 strain grown in a rich (TM) medium at 60 M-BM-0C under the dark condition compared with that of wild-type. Three wild-type strain of T. thermophilus HB8 were pre-cultured at 60 M-BM-0C for 16 hours in 100 mL of TM medium containing 0.8% polypeptone, 0.4% yeast extract, 0.2% NaCl, 0.4 mM CaCl2, and 0.4 mM MgCl2, which was adjusted to pH 7.5 with NaOH. The cells (1 mL) were inoculated into 100 mL of the synthetic medium and then cultivated at 60M-BM-0C for 8 hours under dark condition. Then the 1.0 mM of ZnSO4 was added into the medium, and continued cultivation. Cells were collected, and then, the expression of each mRNA was analyzed.

mRNA expression under alkylating condition in wild-type strain and ttha1564 deletion mutant of Thermus thermophilus HB8

Project description:We analyzed the expression profile of wild-type strain and ttha1564 deletion mutant strain of Thermus thermophils HB8 under alkylating condition. In wild type strain, 107 genes and 96 genes were over 2-fold up- and under 0.5-fold down-regulated by alkylation, respectively. In ttha1564 deletion mutant, 35 genes and 12 genes were over 2-fold up- and under 0.5-fold down-regulated by alkylation, respectively. Keywords: stress response comparison The T. thermophilus HB8 wild-type and delta ttha1564 strains were cultured in TT medium (0.4%(w/v) polypeptone, 0.2%(w/v) yeast extract, 0.1%(w/v) NaCl, 0.4 mM CaCl2, and 0.4 mM MgCl2, (pH 7.5)) at 70M-BM-0C until the OD600 reached 0.8. The cultures were then divided into two flasks and an equal volume of TT medium prewarmed at 70M-BM-0C was added. One of the media culture of each strain contained 100 micro g/ml MNNG. We confirmed that the cells can continue to grow in TT medium containing 100 micro g/ml MNNG but DNAs are alkylated sufficiently (Onodera, 2011). After further cultivation at 70M-BM-0C for 10 min, the diluted cultures were collected into an equal of 100% ethanol and stored at -80M-BM-0C. The procedures used for extraction of crude RNA, synthesis of cDNA, labeling of cDNA fragment, hybridization to a TTHB8401a520105F GeneChip (Affymetrix) and data analysis were basically the same as those described previously (Agari et al., 2008; Shinkai et al., 2007). To determine the mRNA expression level of each sample, image data for the three independent samples were processed. stress response comparison

Comparative genomic hybridization of strains of Leishmania infantum wild-type and five independent 5-fluorouracil resistant mutant.

Project description:The genomic DNAs of strains 263 of L. infantum and five derived independent resistant mutants to 5-fluorouracil were used in comparative genomic hybridizations to reveal the deletion and/or amplification events occured by drug resistance mechanisms. The human protozoan parasites Leishmania are prototrophic for pyrimidines and de novo pyrimidine biosynthesis is necessary for their growth. Five independent L. infantum mutants were selected for resistance to the pyrimidine analogue 5-fluorouracil (5-FU) in the hope to better understand the metabolism of pyrimidine in Leishmania. Analysis of the 5-FU mutants by comparative genomic hybridization and whole genome sequencing revealed amplification and deletion events as well as point mutations in metabolic genes involved in either the uridine salvage, folate or dTMP biosynthesis pathways. In particular, a dhfr-ts containing amplicon was observed in two mutants and a deletion of part of chromosome 10 was detected in one mutant. Point mutations in uridine phosphorybosyl transferase (UPRT), thymidine kinase (TK) and uridine phosphorylase (UP) were also discovered. Transfection experiments confirmed that these molecular alterations were responsible for the 5-FU resistance phenotype. Transport studies revealed that one resistant mutant was defective for uracil and 5-FU import although the identity of the transporter remains elusive. This study provided further insights in pyrimidine metabolism in Leishmania and confirmed that multiple mutations can co-exist in a cell to lead to resistance. Each independent resistant mutant to 5-fluorouracil was hybridizated with the wild-type L. infantum 263 to 10 microarrays, each with three biological replicates (independent cultures).
