Project description:Analysis of whole genome bisulfite data for 3 maize inbred lines (B73, PH207, and W22) with data aligned to the corresponding genome for determination of methylation level (CG, CHG, and CHH) across 100bp windows of the maize genome.

Project description:This was a pilot project carried out by Dr Wojciech Majeran to determine the maize pollen proteome harvested from field-grown W22 (T43) plants in plots on the Musgrave Research Farm (Cornell CALS) in Aurora (NY). To enhance proteome coverage, the pollen were separated into soluble and membrane bound protein fractions, and separated by SDS-PAGE followed by in-gel digestion and shot-gun proteomics using a nanoLC-Orbitrap system.

Project description:The goal of the project is to produce a standard annotation of the loci producing small RNAs in the maize genome. To achieve this goal we produced small RNA libraries from four different maize tissues, which will allow the identification of tissue-specific small RNA expression. The availability of bilogical replicates for three of the four tissues analyzed will guarantee robustness in the small RNA genes identification process. sRNA profile of maize expanded leaf, wrapped leaf, pollen and embryo, collected from B73 wt plants grown under control conditions. Leaves and pollen samples are replicated three times, embryo one time.

Project description:Expression profiling analyses for eight maize inbreds reveals extensive transcriptional variation. Many genes exhibit presence-absence variation among the inbred lines. Experiment Overall Design: Affymetrix expression profiling was used to study gene expression in aerial tissue from 11-day seedlings of maize. Three biological replicates were performed for eight different inbred lines; B37, B73, B84, Mo17, Oh43, B14a, Wf9 and W22.

Project description:Expression profiling analyses for eight maize inbreds reveals extensive transcriptional variation. This is a companion dataset to an Affymetrix profiling experiment (GEO Series GSE10237). Keywords: Genotype comparison series Expression profiling was used to study gene expression in aerial tissue from 11-day seedlings of maize. Three biological replicates were performed for eight different inbred lines; B37, B73, B84, Mo17, Oh43, B14a, Wf9 and W22.

Project description:In this study, RNA-seq based comparative transcriptome analysis was used to study the genetic response of maize silk to pollen tube penetration and in comparison to the fungal invasion of Fusarium graminearum and Ustilago maydis. RNA-seq libraries of 8 tissues were generated from leaf, root, seed, pollen tube, silk, pollinated silk, infected silk with Fusarium and infected silk with Ustilago.

Project description:The goal of this work was to identify transcripts in maize endosperm that are regulated by water stress and the transcription factor Vp1 Keywords: stress response Plants were grown from F1 hybrid seed produced from inbreds W22 and ACR5855, where both inbred parents contributed mutant vp1-R alleles. Florets were fertilized with pollen from either homozygous vp1 pollen, thus creating vp1/vp1/vp1 mutant endosperms, or Vp1 pollen, thus creating Vp1/vp1/vp1 endosperms. Water stress treatment was imposed by withholding irrigation at 5 days after pollination; endosperms were sampled at 10 d after pollination. The study had 2 X 2 factorial design with two genotypes and two watering treatments; there were 6 biological replicates.

Project description:In this study, we sequenced four small RNA libraries derived from mature pollens, in vitro germinated pollens, mature silks and pollinated silks of maize, respectively. In total, 161 known miRNAs belonging to 27 families and 82 novel miRNAs were identified. Of them, miRNAs involved in pollen-silk (pistil) interactions were analyzed. On the male side, miRNA differentially expressed between mature and germinated pollen were identified, some of them participate in pollen germination and tube growth. On the female side, silk-expressed miRNAs respond to pollination were also responsive to stresses, especially drought and fungal invasion. Furthermore, GO analysis of target genes revealed that members related to anxin signal transduction and gene expressional regulation were overrepresented.The results indicated that during pollen-silk interactions, miRNAs-mediated auxin signal transduction plays important roles, and miRNAs took part in complex transcriptional regulating network. Examination of 4 different tissues of maize to provide novel information for understanding the post-transcriptional regulations of pollen-pistil interactions
