Genome-wide transcriptome analysis of two maize inbred lines under drought stress during the seedling stage
  • organism-icon Zea mays
  • sample-icon 23 Downloadable Samples
  • Technology Badge Icon Affymetrix Maize Genome Array (maize)

Description

To understand the transcriptome changes during drought tolerance in maize, the drought-tolerant line Han21 and drought-sensitive line Ye478, which show substantial differences in drought tolerance at the seedling stage, were selected for this study. Using the GeneChip Maize Genome Arrays, we applied genome-wide gene expression analysis to the two genotypes under gradual drought stress and re-watering. We identified 2172 common regulated transcripts in both lines under drought stress, with 1084 common up-regulated transcripts and 1088 common down-regulated transcripts. Among the 2172 transcripts, 58 potential protein kinases and 117 potential transcription factors were identified. The potential components of the ABA signaling pathway were identified from the common regulated transcripts. We also identified 940 differentially regulated transcripts between the two lines. Among the 940 transcripts, the differential expression levels of 29 transporters and 15 cell wall-related transcripts may contribute to the different tolerances of the two lines. Additionally, we found that the drought-responsive genes in the tolerant Han21 line recovered more quickly when the seedlings were re-watered, and 311 transcripts in the tolerant Han21 line were exclusively up-regulated at the re-watering stage compared to the control and stress conditions. Our study provides a global characterization of two maize inbred lines during drought stress and re-watering and will be valuable for further study of the molecular mechanisms of drought tolerance in maize.

Transcription profiling by array of rice with chalky grain endosperm
  • organism-icon Oryza sativa
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Rice Genome Array (rice)

Description

A near-isogenic rice line CSSL50-1 with high chalkiness and Asominori (the parental line) with normal grain endosperm were used for comparative studies of rice grain endosperm chalkiness,transcriptome comparison of 15 DAF caryopses using Affymetrix rice GeneChip identified differential expressed genes between these two lines.

Expression data from infected (Xanthomonas oryzae pv. Oryzae (P10)) leaf in japonica rice (cv. Y73)
  • organism-icon Oryza sativa
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Rice Genome Array (rice)

Description

Previously, we successfully introduce the bacterial blight resistance trait from Oryza meyeriana into O. sativa using asymmetric somatic hybridization with O. meyeriana as the donor species. After years of breeding, a progeny named Y73 was generated with recurrent parent O. sativa L. ssp. japonica cv. Dalixiang, and it shows high resistance to broad-spectrum of bacterial blight pathogens Xanthomonas oryzae pv. Oryzae (Xoo). However, the resistance mechanism of Y73 is remain undiscovered. To provide insights into the high resistance phenotype of these plants, we examined the transcriptome response in leaves of Y73 to the bacterial blight infection in this study. Xoo inoculated and mock inoculated rice plants were grown in growth room and the global analysis of gene expression events in rice leaves at 24 hours post inoculation (hpi) were analyzed using Affymetrix Rice GeneChip microarrays.

Comparison of transcriptome profile between wild-type and Epi-df mutant plants
  • organism-icon Oryza sativa
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Rice Genome Array (rice)

Description

We identified and characterized a rice epigenetic mutant Epi-df which exhibits a dwarf stature and various floral defects that are inherited in a dominant fashion. We demonstrated that Epi-df participates in Polycomb repressive complex 2 (PRC2) mediated gene silencing. Epigenetic mutations results in ectopic expression of Epi-df and pleiotropic developmental defects in mutant plants. Moreover, ectopic expression of Epi-df leads to mis-regulated H3K27me3 and changed expression of hundreds of genes involved in a wide range of biological processes.

Transcriptional profile of Escherichia coli K12 strain JM109 under 200 mM glyphosate shock
  • organism-icon Escherichia coli
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix E. coli Genome 2.0 Array (ecoli2)

Description

Glyphosate (GLY) is an effective antimetabolite that acts against the shikimate pathway 5-enolpyruvylshikimate 3-phosphate (EPSP) synthase, However, little is known about the genome-scale transcriptional responses of bacteria after glyphosate shock. To investigate further the mechanisms by which E. coli response to a glyphosate shock, a DNA-based microarray was used for transcriptional analysis of E. coli exposed to 200 mM glyphosate.

Description

A1501 aroA is a gene derived from Pseudomonas stutzeri A1501, encoding a class II glyphosate-tolerant EPSP synthase. To understand the effect of class II EPSP synthase to E. coli under glyphosate shock, we constructed the class II EPSP synthase-expressing plasmid pUC-A1501. And pUC18 is the empty vector used as a control.

Gibberellin-induced gene expression in maize mesocotyl under deep-sowing condition
  • organism-icon Zea mays
  • sample-icon 6 Downloadable Samples
  • Technology Badge Icon Affymetrix Maize Genome Array (maize)

Description

In order to elucidate the molecular mechanism of gibberellin (GA)-induced mesocotyl elongation, gene expression profiling analyses were performed in a deep-sowing tolerant maize inbred line 3681-4. Gene expression studies combing Affymetrix GeneChip analysis and Real-time PCR were employed to determine the molecular mechanism underlying GA promotion of maize mesocotyl elongation. These studies showed that the GA receptor GID1, the transcriptional factor MYB, and the genes encoding DELLA protein DWRF8, kinases, Raf, LRR, RLCK, and involved in flavonoid biosynthesis, aminosugars metabolism, cell wall synthesis and modification, might play critical roles in maize mesocotyl elongation.
