TranscriptomicsUV Radiation gene profiling in Maize Genotypes with Varying Flavonoid Content
Microarray hybridization was used to assess acclimation responses to four UV regimes by near isogenic Zea mays lines varying in flavonoid content.

TranscriptomicsZea mays B73 stress treatments on UA 70mer oligo slides (Maize oligo array version 1.3 array A and B)
Maize seedling transcriptome responses to six abiotic perturbations (heat, cold, darkness, desiccation, salt, UV-B) and 2 controls were analyzed Keywords: comparitive transcriptome profiling Tissues were grown at Stanford University during the summer of 2005. RNA was extracted and purified, cDNA ge...

TranscriptomicsGene expression profiling of maize anther and pollen ontogeny
Global gene expression profiles of seven stages representing 29 days of anther development are analyzed using a 44K oligonucleotide array querying ~80% of maize protein-coding genes. Each anther stage expresses ~10,000 constitutive and ~10,000 or more transcripts restricted to one or a few stages. ...

TranscriptomicsMaize tumors caused by Ustilago maydis require organ-specific genes in host and pathogen
Two-organism transcriptome profiling of infected seedling, adult leaf, and tassel demonstrated that both the host and pathogen exhibit organ-specific expression programs. Phenotypic screening of U. maydis mutants deleted for suites of secreted protein genes and maize growth mutants demonstrated org...

TranscriptomicsTranscriptome profiling of maize anthers using genetic ablation to analyze pre-meiotic and tapetal cell types
Agilent oligonucleotide arrays were used to profile gene expression in dissected maize anthers of 3 types of male-sterile plants and their fertile siblings at four stages of development: after anther initiation, at the rapid mitotic proliferation stage, pre-meiosis, and meiotic prophase I. The male...

TranscriptomicsCornChip0-Maize Pilot GeneChip Array
To define the parameters necessary to design short oligo arrays for maize (Zea mays L.), a species with particularly high nucleotide (SNP) and insertion-deletion (indel) polymorphism frequencies, gene expression was analyzed in for four maize inbred lines using a custom Affymetrix DNA array. Statist...

TranscriptomicsPreliminary exploration of Oryza sativa small RNAs - Run 1 and 2
The small RNAs presented here were produced as a preliminary exploration of small RNAs in rice, and as such, various tissues and stress conditions were sampled. Small RNAs present in these samples were all mapped to the rice genome TIGR version 5. The total number of distinct mapped sequences are ...

TranscriptomicsEndogenous small RNAs of meristematic and a terminally differentiated tissue of rice.
To address the role of small regulatory RNAs in rice development, we generated a large data set of small RNAs from root apices (RoApx), shoot apices (ShApx), developing inflorescence (Infl) and mature leaf (Leaf). These tissues were chosen because they are expected to be rich in small RNAs and displ...

TranscriptomicsHypoxia triggers meiotic fate acquisition in maize
Evidence from confocal microscopic reconstruction of maize anther development in fertile, mac1 (excess germ cells) and msca1 (no germ cells) flowers indicates that the male germ line is multiclonal and uses the MAC1 protein to organize the somatic niche. Furthermore, we identified redox status as a ...

TranscriptomicsThe male sterility 8 mutation of maize disrupts the temporal progression of the transcriptome and results in the mis-regulation of metabolic functions
Phenotypes of maize male sterile 8 plants are small anthers, meiotic failure, shorter epidermal cells, and non-secreting tapetal cells. Excess callose accumulates around meiotic cells, which later abort. Thousands of transcriptome changes occur including ectopic activation of genes not expressed in...
